Introduction

If your vehicle already has a towbar, you are probably settled, but you might still find some interesting information in this article.

Having a towbar installed provides several benefits, apart from the obvious role to tow a trailer.

Terminology

• A tow bar is a transversely-mounted rail (typically hollow, but made of thick metal), which is mounted on vehicle's rear chassis rails (in factory-made mounting points on the chassis rails).
• A tow neck is a short pipe or plate which is welded or bolted on to the center of the towbar, and protrudes orthogonally to the towbar itself
• A tow ball is a non-hollow metal ball onto which you actually clamp the towed or carried object.

Notes on terms

• Sometimes the term "towbar" is applied to the entire assembly (tow bar + tow neck + tow ball), but sometimes it means strictly only the tow bar itself. It depends on the context.
• Tow neck can be die-cast as a single piece together with the tow ball, or be a separate piece.
• Tow ball dimensions are defined by international standards.
• Sometimes the term "towball" is applied to the entire "tow ball + tow neck" assembly (especially if they are die-cast as single piece).

Types of towbars

There are several different general designs of towbars for Jimnys.

They depend both on the region of the world and on the era when they were made (remember, Jimnys have been in production since 1998).

The design differences concern primarily the design of the tow neck section.

Some towbars (primarily very old ones) use fixed tow necks - they are welded to the towbar.

Most newer towbars use detachable tow necks (tow neck can be disconnected from the towbar). The methods of (de)attaching the tow neck vary significantly (from having to use tools and spanners to having some various convenient "click-on" or "push-in" systems). This depends on the manufacturer.

The length of the tow neck varies significantly depending on the model of the towbar, and this plays an important utility and safety role. Some tow necks are even significantly longer than the spare tyre. Read more about this below.

Benefits, issues and risks

Benefits

1. You can tow a trailer (obviously).
2. You can carry a bicycle carrier.
3. You can carry a cargo box - typical use is to transport hunting dog(s).
4. Towbar weights approx 15 - 20 kg, so it adds beneficial weight on Jimny's rear axle, slightly decreasing vehicle's tendency to slide in bends and to wheel slip in 2WD mode on wet tarmac.
5. When offroading, if you exceed vehicle's departure angle, the towbar is most likely to impact the ground before the rear bumper or other vulnerable body parts. It is much better to hit the towbar than anything else in the rear. Towbars can take a beating.
6. You can weld on a pair DIY "recovery" points between the towbar and vehicle's rear left and right factory tow points. When combined, those should provide good anchorage. Then you can attach shackles on those points for recovering the stuck vehicle.
7. Having a towbar fitted makes your vehicle appear more serious (if that turns you on).

There are no technical disadvantages of having a towbar, except possibly a minuscule increase of fuel consumption because of added weight.

Legal issues

In some regions of the world, like some European Union countries, there could be various legal restrictions on using the towbars.

1. You might not be permitted to have a tow neck + tow ball attached to the towbar when you are not towing a trailer or carrying a bicycle carrier (that is why detachable tow neck designs primarily exist).
2. It might pose a legal issue if the tow neck + tow ball protrudes further than the spare tyre.
3. Installing a towbar on a vehicle "afterwards" (after the vehicle was sold as new from a saloon without the towbar) might require some vehicle recertification in some countries, even if it is a OEM towbar.
4. UK specific rule: Standard towbars (including those supplied by Suzuki!) can be illegal as the tow ball obscures the number plate. A lot of MOT inspectors let this go, but enforcement is getting more widespread now.

Tow hitch

This is a typical tow hitch sold in the UK. The towball should not be left in place in normal driving as it obscures the number plate.

Risks

1. If a vehicle rams you from behind while your tow neck is fitted, that vehicle might sustain nasty damage to its front end, especially if your tow neck is longer than the width of your spare tyre.
2. If you reverse in a parking lot for example with the tow neck fitted, you need to be more careful not to hit another vehicle with it.

Warning: NEVER attach a rope or strap to a tow ball or tow neck when recovering a stuck vehicle or when someone is recovering your stuck vehicle !!! Although it might seem like a logical attachment point when recovering, tow balls and tow necks are not designed to endure shock loads which can be enormous when recovering a stuck vehicle. If a tow ball or tow neck breaks off under load, it becomes a lethal flying missile. Broken off tow balls have destroyed other vehicles and killed people in spectacular manners! You certainly do not want to participate in such a spectacle!

Buying a towbar

The best place to buy a towbar would be from a dead Jimny in a vehicle junkyard.

You can of course buy a new OEM towbar from Suzuki, but expect a very high price.

There are many aftermarket manufacturers of towbars, and some of them make the models for Jimny. An example is Westfalia.

Manufacturing a custom towbar

In certain regions of the world, there are workshops which manufacture custom towbars. It is usually some generic design adopted to a particular vehicle. They usually also supply some certificate along with the manufactured towbar.

If you can not obtain a genuine or afermarked made towbar which was specifically made for Jimny, taking your vehicle to such a workshop to have this "generic" towbar customized for it might also be a practical solution.

Using bicycle carriers or cargo boxes

Bicycle carriers

The wiki article Bicycle carriers contains everything about choosing and using bicycle carriers on a Jimny, including towbar mounted ones.

Cargo boxes

The wiki article Cargo space expansion and management contains a dedicated chapter about towbar mounted cargo boxes and dog boxes.

Common remarks

Beware that the load limit for most towbars is in the range of 50 - 75 kg! You must count in the weight of a bicycle carrier or cargo box together with the bicycles or cargo when doing the weight calculation.

Note: Using towbar mounted bicycle carriers or cargo boxes can have legal restrictions in some countries. Examples could be mandatory additional license plates and brake + turn lights on those objects, or issues of animal treatment if transporting hunting dogs, etc. These all are non-Jimny related generic issues which you need to explore on your own.

Wiring issues

If you do not intend to tow a trailer, or are not required to have additional brake+turn lights on towbar mounted cargo boxes or bicycle carriers, then you do not need to install wiring for the towbar electrical socket.

If you have to install wiring for the towbar, there are several solutions available.

Suzuki did not install wiring for the towbar in Jimnys which did not have factory-fitted towbars.

You can buy OEM towbar wiring kit from Suzuki. The exact details on part numbers are not yet investigated, but the price is certainly high.

Alternative is to install custom wiring, but this is best left to be done by professional vehicle electricians. Exact details and user experiences on this matter should be added into this article by other wiki members.
