FJ40 clearence

[Short45]

Hi all i have a small issue with my cut down FJ40 .
The rear tyres hit the cab when flexing.
My question is what have people found to be the best sollution for relocating the rear diff back.

Any help / advice would be great.

longer springs. What years is your shorty? This will determine if it has small spring mount eyes or large ones and in turn what springs to use. Typically if it is small eye mounts use FJ55 rear springs. If it has large eye mounts use either front 75 series or rear 60 series springs. You will need to flip the rear hanger if you use 60 series springs (they are longer than front 75 series). Whichever ones you use you should customise the leaf pack to suite your vehicle. Moving the rear axle back will also require tailshaft lengthening. You may also need brake line lengthening and longer shocks.

There was a website I found once with a lot of information about this swap, I think it was an Australian 4x4 forum and it even had a search function.

Luckily for you I bookmarked it, here.

I redrilled the spring perches to move the rear diff back 37.5mm. I didnt bother with longer brake lines and driveshaft modifications, although a 40mm driveshaft spacer will bring the slip joint roughly back to where it should be.. Can be done in an hour and costs nothing.

This is how it was completed originaly but now has 35's and has sagged a little.
Thanks for the info will look @my options .
The car started as a 1978 FJ40.

Thanks Chris

if it is a 78 model it will have the small spring eyes. I have a set of rear 55 series springs if you like. Car looks very neat and tidy.
