Re:Are heavy duty rear springs available or are......

I don't know if they make Jimny springs or if they will make you a one off set. They are here just in case nothing else pops up.

They may just make cart springs, but could be worth a call.

I can vouch for Jones' springs being exxcellent - they made the springs for my vintage MG - they were very easy to deal with and the turn around time was very reasonable

I think your easiest solutions have been provided by Dave with either Jimny Bits diesel front springs on the rear or just add poly spring spacers to your current springs.

I think I'd try the spring spacers to start with due to their low cost. Obviously you are not increasing the spring rate so I'm assuming that you're happy with how it drives now but just want to correct the height.

I think first of all I'll try and fit a set of standard front springs that I have spare on the rear and take it from there. The standard brake hose at the back will be a bit tight though during fitting (it was a squeeze fitting a standard rear spring in) so ill need to investigate if i can create a bit of slack on the brake line or if i can get in with spring compressors.

that might be enough to support the rear better. and so long as the car looks and feels level then that might be it, if not i'll look into upgrading the front with diesel springs.

I do remember reading one of Dave's daily drive builds on here where he fitted front springs to the rear i think (standard shocks with shock re-locators) and different stuff to the front (vitara rear shocks on the front with springs and spacers?) but id need to go for a search, It peeked my interest when he posted it a while back.

Thanks again folks

Blimey, yeah, if you already have some front springs, stick them in. You've got nothing to lose!

There's plenty of room for spring compressors.

Just remove the clips that hold your brake pipes
One on the axle and other on chassis rail up the side of petrol tank
I fitted +2" springs this way

Well, I gave fitting a spare set of front springs I have to the rear of my Jimny a go.

Here is a bit of a break down on what I found/done.

To start with,
Standard spring lengths, by my unscientific measure methods.

Fronts 340mm
Rear right 290mm
Rear left 273mm







The car still has all my usual stuff in the boot, and a 2nd battery behind the drivers seat to power my Yaesu 2m radio, tow bar is fitted along with my full steel JimnyBits roof rack and is on 205/75/15 general grabbers.

Before heights from ground to top of arch
Rear right 715mm
Rear left 735mm
Front left 745mm
Front right 740mm
Ground to bottom of towbar hitch 265mm












I then jacked up the car via the tow bar to have the suspension at full length with the tyres still on the ground, 395mm




Front spring remain unchanged,
Rear springs swapped out for a 2nd sets of fronts.


After heights from ground to top of arch
Rear right 755mm
Rear left 775mm
Front left 760mm
Front right 740mm
Ground to bottom of towbar hitch 310mm












And an after measurement where I jacked up the car again via the tow bar to have the suspension at full length with the tyres still on the ground, 395mm



If I get a chance I’ll remeasure tomorrow to see if the after measurements have settled any after driving and I’ll update them. First impressions are positive, car now sits better at the rear, there is space between the rear bump stops and the axle (before it was a finger width away, but I forgot to take this measurement).
There still is room for the suspension to extend.


All measurements are indicators and are a few mm’s out going by the photos but this info might be of use to someone.

Thanks for the help and info that you guys provided, if this doesn’t work out in the longer term then I’ll look into the other springs suggested.

Thanks again for all the info.

Tony.
