Thread: Poly bushes

IMO - Use OE bushes, not poly.

I'd much rather replace worn out rubber bushes than replace stress fractured suspension components.

years ago we used to run poly bushes on a fleet of Landcruisers in central australia. they improved the handling of the truck quite a bit, but passed a lot of stress on to the rest of the chassis and bodywork. The Cruisers started to crack in various spots, but that brilliant 4.2 never let us down. ( the stiff after market suspension didn't help )
I only use original rubber bushes on my trucks, some of my customers run polybushes blue, which are ok and easy to fit.

so we are talking the lower trailing arm, chassis end ?

If so, check out Super Pro's (made by Fulcrum) bush. Not cheap, but IMHO a far better design than OE. I've been using them for 4 or 5 years now and no problem. The design reduces the pounding out that the OE rubber one experiences and allows better articulation. A win-win.

and again I say, depends on the bush, depends on the durometer (hardness).

Poly bushes have been in my radius arms for at least the last 100,000km.
Still haven't worn out but they do increase the front roll stiffness a lot.

I put them in the panhard maybe 30,000km ago. No issues there.

I am going to use a swear word here but 10 years or so ago I worked for Toyota and I remember knocking back warranty claims on 80 series with Poly Bushes. They were too stiff and the end result was cracked diff housings.
Well thats what the engineers said at the time

Rubber = Good

anything else = rubbish

dont argue with me, if you want to use rubbish its fine

Landcruisers will crack on central Australian roads no matter what suspension they use.
