Those with retained springs...

[Michele]

...any failure/crack of the upper spring seat or retainer itself?

I'm having my retainers made,a 2 x discs up and 2 x bars down and 2 x bolts through...

I'm wondering if/when the spring stretches...what kind of strain does it put on the spring seat?
Anybody experienced failures of some kind in the long term?

[DK]

I have never had any troubles and i dont think the strain is all that much..
I only use a couple of hose clamps on the upper rears and only break them occasionly...

Michele - if you are worried it is pretty easy to work out the loads. What is your spring rate and how far do you expect the spring to stretch.

e.g. 150lb/in springs, and let's say you get an ABSOLUTE maximum of 2" stretch, then that would be a load of 300lbs (but I doubt you would ever get that much stretch).

Is it warm and sunny there?

Oh and btw - I will be back in europe soon - pm or email if you want to catch up.

The extension forces will be less than the compression forces, so don't worry, be happy.

You could always get one of these... http://www.x-eng.co.uk/X-Spring.asp?MID=57

[KiwiBacon]

Wouldn't your max extension force be the back half vehicle weight leveraged off the opposite side spring?
This would be shared by the spring (extension*rate as Isuzurover said) and the shock will take the rest (if it's topped out).

But yeah, always much less than maximum compression force.

I have bent the upper spring purch twice, it is now re-enforced

You had some crappy plates though Ash, besides the 10 winds of fencing wire is still working OK on your Rangie last I saw it in my shop a couple of weeks ago

Yes, but are they bent from the spring pulling or pushing on them???

Most I have seen are from people using longer springs that bottom out before the axle can hit the bump stops.

(in the meanwhile,in another galaxy...)

I got my retainers and fitted them this morning.

So far I managed to bend the lower bar while tightening the bolts...
...not bad,considering I have yet to test it out in the field...

2 inch stretch mine stretch 4 inches then bend the 5mm flat bar retainers
