What corrections needed for 40mm lift?

I just bought a second hand 2015 JLX Jimny. This is my first four wheel vehicle.

The previous owner had an OME 40mm lift installed with Kumho KL71 LT215/75R15 tires. Castor correction bushes were installed on the front, mud guards trimmed, and a 1" trim pack/bushing on the front springs were installed to make the Jimny level.

I've read of some modifications that others have done after lifting the Jimny to correct any issues, and I am wondering what I also need to do for mine. I've read of:

* Castor correction bushes in the rear
* Propeller shaft spacers
* Brake balance valve correction bracket
* Rear shock relocators
* Panhard rods
* Steering spacers (or is this only for body lifts?)
* Bump stops

I have no plans to do off-road driving with this yet. I am using the Jimny as my daily driver now.

On a 40mm lift you shouldn't need much castor correction if it drives ok.

Similarly the props shouldn't be an issue.

Being a 2015 it will have abs and therefore no brake biasing valve to worry about.

If it is fitted with a suitable quality kit the damper should be matched with the springs and won't need relocation mounts. This is open to interpretation as some people believe relocation has a significant positive role, others think it's totally unnecessary.

Panhards will only be needed if the lift has significantly pushed the axles to one side of the centre of the car. A little lift shouldn't be particularly noticeable.

Steering spacers are for body lifts

Longer bump stops are necessary if on full articulation either the wheels are catching the body or if the dampers are bottomed out before the bump stops are working.

Thank you for the very detailed response.

I don't think the 2015 JLX for the Philippine market has ABS installed. The previous owner is unsure if there is one. The ABS indicator doesn't light up when the ignition is ON. The brochure also specifies "N/A" for ABS.

Ah in that case look for a big spring attached to the back axle and the other end to a lever on a block with brake lines. There are kits that account for a lift available usually with a different lever or spring length.

Alternatively make a bracket that moves the axle end of the spring back to the normal operating ranges.

Ramon, you are correct that the 2015 Jimny (Philippine market) doesn't have ABS. I think they only came with ABS starting this year.

I am also in the Philippines and have a 2015 Jimny with OME springs and 215/75r15s. All I can say is that Lambert covered everything as well as it can be.

I started out with nothing & still have most of it left

On a 50mm lift you don't need castor correction, so you won't need it with a 40mm lift.

I am having trouble locating the LSPV. I also can't find any pictures of the location with the surrounding areas to help me locate it.

Did you also had front spacers installed to make your Jimny level?

I fitted a 2inch(40mm) suspension lift kit recently, and despite most saying a castor correction kit was required(bushes etc)..i found it unnecessary, i do have a steering damper fitted also, i think because of this possibly, i didnt find any wandering or vagueness on steering mentioned by a lot of people..In fact i found it drives better than before, also ride is improved.
Alot i thinbk depends on how your vehicle has been looked after generaally, if its been a high miler, a lot of other factors will come into play, basically general wear on drive/suspension components, fortunately when i did my mods, it was on a low mileage jimny, only 32000.
So, maybe this is why i havent experienced any of the hassles others had.
I fitted a black raptor 2inch lift, springs and shocks, although this in others opinions is a low budget kit, i find its performance very good for the money spent.
And it really does improve my jimny.,

My Jimny is also "young", only 25K mileage. I haven't installed a steering damper yet but I am thinking about it. We have really bad roads in the Philippines and it's sometimes terrifying to have a sudden steering kickback at 40km/h with scooters all around you.

I would suggest a steering damper is a really good addition, it does get rid of the vague feeling most jimny's have..it doesnt self centre so readily once fitted, but you soon automatically respond to that, took me a day or so to adjust to it, but you really will notice a big improvement, it feels like it should do..responsive, and not so skittish over road irregularities..

I disagree. Castor correction bushes should be included in the kit in my opinion.
The car is much better on the road with castor correction than without.
I think it drives awful without them.

depends of course on taste and what you prefer, but i like the car to self align after turns like it did before the lift.

Another thing is that most correction bushes for 2" lift does not correct the castor fully as they have too little correction.
