Introduction

Jimnys 3 were produced from 1998 to 2018, and there have been three front bumper models / editions on them:

1. 1st model bumper (1998-2006)
2. 2nd model bumper (2006-2012)
3. 3rd model bumper (2012-2018)

All of those are made of plastic.

Main characteristics of each bumper model / edition:

• The 1st model bumper is the smallest one (does not hang too low to the ground).
• The 3rd model bumper also is not bad.
• However, 2nd ed. bumper is overly large (hangs very low to the ground), and it significantly reduces the approach angle.
  • The risk of it hitting the ground is quite higher than with other two bumper models.

Problems with 2nd ed. front bumper

• The 2nd ed. front bumper is the most endangered point when off-roading, and it's easy to damage.
• Also, 2nd ed. bumper reduces the space around the front wheels, limiting the size to which the wheels can be increased (by using larger tyres).
  • With 2nd ed. bumper, the usual tyre size limit is 205 / 75 / R15 (and even that size sometimes makes a contact if the bumper is sagged).
  • On the other hand, with the 1st ed. bumper, even 215 / 75 / R15 is usually not a problem.

The 3rd ed. front bumper is also a bit restrictive in regards to the above issues, but not as much as the 2nd model front bumper.

Solution 1: Trimming the front bumper

• Trimming the lower part of a front bumper is the quickest and (seemingly) the simplest solution to increasing vehicle's approach angle and free space around front wheels.
• Because of all the mentioned problems with the 2nd model front bumper, many people trim the bottom half of the 2nd model front bumper, but it tends to look ugly.
• Also, if you trim a 2nd model or 3rd model front bumper, you would probably lose your front fog lamps (if you have them) and a place to hold the front license plate.

Alternative solution to trimming a front bumper is to replace it with something else.

Examples of trimmed 2nd model front bumpers

• Example 1 of trimmed 2nd model front bumper
• 

  License plate attached, but it hangs and could easily rip off.

• Example 2 of trimmed 2nd model front bumper
• 

  License plate kept indoors. This might not be legal everywhere.

• 

  Side view of the result.

• Notice that the resulting trimmed 2nd model front bumper (in both examples) is actually only slightly shallower than a stock (unmodified) 1st model front bumper.
• Some people trim the 1st model front bumper as well.
  • However, if you really need such high approach angles, then your vehicle is probably already so much modified that one more ugly trim does not matter for the aesthetics or fog lamp / license plate functionality.

Solution 2: Factory bumper model swap

Main idea

• If you have a 2nd model front bumper, and you find that it obstructs your vehicle's off-roading "potency" (or limits your intentions on using larger tyres), the best alternative is to buy a second-hand 1st model front bumper (1998-2006) from a scrap yard (or exchange it with another Jimny owner), paint it if needed, and install it instead of the 2nd model front bumper.
• You could even swap a 3rd model front bumper with a 1st model front bumper if you want some more clearance.
  • However, the difference is not so pronounced as with a change from 2nd model to 1st model front bumper.

• The mounts for attaching a bumper on the vehicle should be (almost) 100% compatible on any Jimny 3 from 1998 to 2018.
  • However, this has not been confirmed by someone yet.
• Replacing one model of a front bumper with another on the same vehicle should be legal (both are genuine parts), and it should not affect the operation of the airbag sensor(s).
  • But this is a theoretical assumption.

1st and 2nd model front bumper on the same vehicle

A side view of a 3rd model front bumper

• Here is a side-by-side comparison of 1st and 2nd model front bumper on the same vehicle.
• The body color differs in the left and right parts of the image because of different lightning conditions.
• The "before" (left) part of the image is with a 2nd model bumper.
• The "after" (right) part of the image is with a 1st model bumper.
• The side view picture of a 3rd model front bumper might not be directly comparable with these two on the left, because it was not taken from the exactly the same angle.

Example pictures of swapped bumpers

Pre-2013 and post-2013 Jimnys 3 have different front bonnet and grille (look at the pictures in the "Introduction" chapter):

• In pre-2013 Jimnys, the bonnet and grille are a single-piece and there are five plastic grille holes / grids in the bonnet itself
• In post-2013 Jimnys, the bonnet is shorter in the front, and there is a large fixed front grille between the front head lamps, reminiscent of a "Hummer-style" front grille.

The picture galleries below show how it looks like when a 1st and 2nd model front bumper are paired with a post-2013 Jimny, and also when a 3rd model front bumper is paired with a post-2013 Jimny.

Pre-2013 Jimny with 3rd model front bumper

It appears that it is not trivial to fit a 1st model front bumper to a Jimny 3 which originally had a 3rd model front bumper. Some parts of the chassis collide with the older bumper, and there are no mounting holes in the top of the old bumper for the center grille (between the head lamps).

However, the swap is still possible after some modifications, as shown in this Russian's report.

Suzuki Jimny 3, built between 2012 and 2018. It originally had a 3rd model front bumper. Now it has a 1st model front bumper.

Additional considerations

Front fog lamps

If you already have front fog lamps in your current/old front bumper, and want to continue having front fog lamps in the new front bumper, the possible solutions depend on which front bumper models you are swapping.

The wiki article "Front fog lamps" contains all the details about front fog lamps.

If replacing 1st model front bumper with 2nd model front bumper:

• By the way, why would you want to do this?
• Jimnys with factory installed 1st model front bumper used two types of front fog lamps:
  1. The older ones which do not have a bezel around them (P.N. 35500-74F50);
  2. The newer ones (P.N. 35500-63J00 or 35500-63J02 or 35500-63J04), which have a surrounding bezel as a separate part.
• If your current 1st model front bumper has the older fog lamp type installed, neither the current front fog lamps nor their carriers/brackets will be compatible with the new bumper.
  • In other words, you will have to obtain an entire new set of front fog lamps (including carriers) which match the new front bumper model.
    • At least you will be able to sell your old front fog lamps+carriers to someone with a 1st model front bumper.
• If your current 1st model front bumper has the newer fog lamp type installed, the current front fog lamps should be compatible with the new bumper, but the carriers will not.

If replacing 1st model front bumper with 3rd model front bumper:

• Jimnys with factory installed 1st model front bumper used two types of front fog lamps:
  1. The older ones which do not have a bezel around them (P.N. 35500-74F50);
  2. The newer ones (P.N. 35500-63J00 or 35500-63J02 or 35500-63J04), which have a surrounding bezel as a separate part.
• If your current 1st model front bumper has the older fog lamp type installed, neither the current front fog lamps nor their carriers/brackets will be compatible with the new bumper.
  • In other words, you will have to obtain an entire new set of front fog lamps which match the new front bumper model (but you do not need the carriers, as the 3rd model front bumper has them integrated).
    • At least you will be able to sell your old front fog lamps+carriers to someone with a 1st model front bumper.
• If your current 1st model front bumper has the newer fog lamp type installed, the current front fog lamps should be compatible with the new bumper, and your current carriers will remain surplus.

If replacing 2nd model front bumper with 1st model front bumper:

• Neither current front fog lamps nor their carriers/brackets will be compatible with the new bumper.
• In other words, you will have to obtain an entire new set of front fog lamps (including carriers) which match the new front bumper model.
  • At least you will be able to sell your old front fog lamps+carriers to someone with a 2nd model front bumper, or just the lamps to someone with a 3rd model front bumper.

If replacing 2nd model front bumper with 3rd model front bumper:

• The current front fog lamps will be fully compatible with the new bumper.
• As the 3rd model front bumper has integrated front fog lamp carriers/brackets, the current front fog lamp carriers from the 2nd model front bumper will become surplus.

If replacing 3rd model front bumper with 1st model front bumper:

• The current front fog lamps will not be compatible with the new bumper.
  • The current bumper has integrated carriers which are not separable anyway.
• In other words, you will have to obtain an entire new set of front fog lamps (including carriers) which match the new front bumper model.
  • At least you will be able to sell your old front fog lamps to someone with a 2nd or 3rd model front bumper.
    • However, your customer with 2nd model front bumper will need a pair of suitable brackets too, which you don't have for them.

If replacing 3rd model front bumper with 2nd model front bumper:

• By the way, why would you want to do this?
• The current front fog lamps will be fully compatible with the new front bumper.
• However, you will need to obtain a pair (left+right) of matching front fog lamp carriers for the 2nd model front bumper.

Additional notes:

• Front fog lamp wiring should be the same for all fog lamps.
• The possible incompatibility of front fog lamp carriers with a different bumper model might be remedied by modifying the carriers (perhaps by some small cutting and/or welding).

Inner front wheel arches

• Inner front wheel arches (black plastic arches) have different length for different bumper models.
  • Your current ones will either be too short with the new bumper, or you will have to shorten them (depending on what you are replacing with what).
• If you are swapping a 2nd model front bumper with a 3rd model or 1st model front bumper (or a 3rd model front bumper with a 1st model front bumper), your old inner front wheel arches will be too long for the new bumper.
  • The simplest remedy is to trim the front bottom part of the inner wheel arches.
    • However, it would be more advisable to buy the matching front inner wheel arches together with the new front bumper.
    • This leaves your old front inner wheel arches intact for future use or for selling.
• On the other hand, if you are (for some impractical reason) replacing your 1st model front bumper with a 2nd model or 3rd model front bumper (or a 3rd model front bumper with a 2nd model front bumper), then you will have to buy the matching front inner wheel arches, because your old ones will be too short.

Front nudge bar (bull bar)

• If your vehicle currently has a metal front nudge bar (bull bar) installed, it probably will not be compatible with a different bumper model.
• If you are swapping a 2nd model front bumper with a 3rd model or 1st model front bumper (or a 3rd model front bumper with a 1st model front bumper), the old nudge bar will fit without any collisions, but its bottom will be too low compared with the bottom of the new bumper.
• On the other hand, if you are (for some impractical reason) replacing your 1st model front bumper with a 2nd model or 3rd model front bumper (or a 3rd model front bumper with a 2nd model front bumper), the bottom of the old nudge bar will most probably collide with the bottom of the new front bumper, because the new front bumper hangs lower towards the ground.

Front nudge bars severely restrict vehicle's approach angle, so they should preferably be removed altogether if the vehicle is used in off road duty. Read more in the wiki article "Bull bar (nudge bar)".

Restrictions with DDiS Jimnys

It has been confirmed that replacing a 2nd model front bumper with a 1st model front bumper is not practical on DDiS (diesel) Jimnys with 63kW (intercooled) K9K 266 engine.

• The problem is that the engine intercooler sits low right up front, just above the right fog lamp.
• If you try to replace the factory-installed 2nd model front bumper with the 1st model front bumper, you will have to discard the right fog lamp (if you have fog lamps).
  • You will also have to leave open the right fog lamp hole in the 1st model bumper, in order to feed the intercooler with air.
    • Even that hole might not be sufficient to feed it with enough air.
  • You should also install some grid in the right fog lamp hole, to prevent an object going through the hole and puncturing the intercooler.
• Alternatively, you could dislocate the intercooler, but the free space in the engine bay is very scarce, and moving the intercooler is an expensive modification on itself.

  The intercooler in all its beauty

Replacing a 2nd model front bumper with a 3rd model front bumper on a DDiS Jimny with 63kW (intercooled) K9K engine would also probably incur the same above issues, but this combination has not yet been tried in practice.

Solution 3: Heavy-duty metal "off roader" ("winch") front bumper

Another alternative to all these factory bumper model swaps or trimmings is to buy an aftermarket heavy-duty metal "off roader" front bumper (also called a "winch bumper").

Advantages of a heavy-duty metal front bumper:

• Prominent looks;
• Takes a beating off road;
• Typically increases the approach angle;
• It can also be used as a mount for driving lamps, winch, high lift jack, machine gun, a statue from the front of a ship, etc.
• You have a right to declare one gear as "ramming speed";

However, metal front bumpers have the following disadvantages:

• They might not be legal in certain regions;
• They increase the weight of the front of the car, possibly sagging the front suspension and increasing its wear;
• They might restrict airflow to the engine cooling system, and to the intercooler (if fitted);
• If they stick too far out to the front, they might actually reduce the approach angle;
• Most metal front bumpers will adversely affect the operation of the airbag sensor(s);
• Most metal front bumpers will adversely impact the fate of anything that collides with them;

If you have a traffic accident while driving a vehicle which has an illegal front bumper fitted (no matter if the accident is your fault or not), you could face severe government penalties + lawsuits from other participants in the accident (for example, from a pedestrian or a child's furious parents whose bones your fancy bumper broke)!

Front bull bars (nudge bars)

These are accessory items which are (technically) not directly related to front bumpers.

Therefore, they have their dedicated wiki article: "Bull bar (nudge bar)".
