Longer springs needed was created by X88RED
Hello all!

Hoping you can all help me out/ point me in the right direction:

I have 4" Rough Country shocks fitted, shock re locators front and rear (front ones add 1.5" and rear ones add 2" to the shock length I believe) and also 2" body lift. I do not want to change this set up.

My issue is that at full flex my springs dislocate and come loose. I have fitted clamps front and rear but obviously the springs are not long enough for my set up and come loose at the top still!

When measuring the length of the springs on the car (when the car is just sitting normally) they measure about 280mm. Not sure if these were rough country springs..

Does anyone know where I can buy longer springs from? and what length would you suggest?

Thank you!

Redmond

www.coilsprings.co.uk/ will make up what you want. They supply a lot of the "generic" springs you see in the various lift kit offerings for the Jimny so already have the specs on record

If nothing else their website is worth reading for the humour on the pages :)

Hi Redmond ;)

As I said in my reply to your email, mine were sourced from another vehicle, after some internet research, and bought them off eBay, they are wound thicker (15mm rather than the diesel 14mm springs) and are suitable for the renowned weight of my Jimny ;)

www.bigjimny.com/index.php/forum?view=to...8&id=53695&start=948

I was worried they'd be too thick and unforgiving, but I'm happy with them for the height and weight of my Jimny -



I haven't said (publically) what they are off, as I believe they might be too stiff for lighter Jimnys, so I don't want to recommend them for others to find they don't suit there own Jimnys... But they do suit my application...

What springs do you have on it at the moment Redmond?

With +4" shocks and all of those shock extenders I'm not surprised your springs are dislocating.

If you already have lifting springs you might just want to get shorter shocks or do away with the shock extenders. I understand the issues with rear shock bottom bolts snapping and premature bush wear but castor correction resolved that for me.

If you have over a 2" lift, do you have castor correction?

I don't see why you shouldn't tell what these springs are off. It's not a matter of recommending them for jimnys in general. But sure would be nice if those with heavily modified jimnys knew there were other options than just springs from jimnybits. Then people can decide for themselves what spring to choose.

Thanks for the input guys! Will research things a bit more..

Kirkynut - I believe the springs are the ones that came with the 4" rough country kit originally although don't quote me for that as they were fitted by the previous owner. I have castor corrected radius arms fitted already which are for 4" lift, I know it is the shock extenders causing the issue but if I can make it work I would like to do so. Especially if it as easy as buying some longer springs that are better suited!

I am swaying towards buying the same springs as Dave tbh - he has 4" suspension lift, shock re locators like me. Only thing is my Jimny will be slightly lighter and I have 2" body lift so it is a bit of a gamble! But then again the ones Dave uses are thicker than most springs on offer so should provide decent support I have also contacted coilsprings.co.uk but waiting on them to get back to me and they will work out a fair bit more.

I personally would just buy some more Rough Country shocks that are suitable for 2" lift and you'll have the right length combo then. The front shock extenders could just come off so you only need new rear shocks.

I have to ask.
Why do you insist on using these shock relocators?

From what I understand better performance off road and less stress on bushes.. also reduces breakage of the axle mount by reducing the forces applied to it - especially on lifted Jimny's like mine. A few people I know run them and get along well with them so thought I would do the same I guess!

It's all just rubbish from those making money selling them.

The stress reduced on the mounts by these relocators is nothing compared with the forces on them from the certical movements of the shocks.

How would it affect offroad performance?
Best case a waste of money. Worst case shock damage due to bottoming out.

Don't believe everything you hear. I know some Jimny owners like to add all sorts of guards, brackets and relocators and what not to their Jimny. But in reality. Most of it is just excessive weight and a waste of money.

If you really want to spend a few bucks making something better. Then it is to make entirely new lower shock mounts on the axles. Especially the front axle.

For comparison i took this pic when changing to the current Zanfi springs (courtesy of TomDK).

The orange one is the trailmaster +2" petrol spring, Green is Zanfi +3" diesel spring (both are fronts).



Mine has a total of +6.5" now, which is made up of the Zanfi springs, 1.5" spring spacers and 2" body. This combination works really well for me, apart from i still have the +2" trailmaster shocks (with Tom's favourite shock brackets/spacer things). Ideally I will remove the shock spacer things when i find some shocks i like and will fit (currently thinking Koni on front and AVO on rear, all adjustable).

Just PM Dave and find out what they are. You can always add some weight to calm it down :laugh:

Just as an addition, I have a 3" lift with castor correction arms and standard shock mounts front and back. I don't get off road these days but I used to all the time with the current set up and nothing broke.

So if you can ditch the shock extenders as Tom suggests, you'll not really be any different to me as your castor arms are for your lift.

Dave's photo shows you don't need them to have flex and I could dig out photos of mine flexing too.

So there's your cheapest and easiest fix.

If you're worried about your rear lower shock bolts shearing, drill through the axle mount on the bottom where the bolt screws in and get a longer bolt and a nyloc nut for it. Martin used to sell them in the Big Jimny shop. You'll need a very good drill bit and some patience mind!
