Guys do the polybush set(Yellow ones IRONMAN) that fits the RR 86 and up(Vogue SE) will it also fit the 1983 RR Carby. Are the mounts similar?
I am assuming it is and there is a set I am looking to buy.

Also how to do you compare the IRONMAN(yellow) to POLYBUSH(Red)
I ran Ironman poly s on my disco for 4 years+ no problems

Will poly s improve road stability?

Poly bushes are a bad idea for coilers - rubber bushes are best.

Though from what I have seen, the colours - from softest to hardest, are:
Blue, yellow, orange, red, black. But I have no idea if this is a uniform standard and suspect not.

Dont do it ! When i got my first rangie 11 years ago i thought the urethane (poly) were a good idea, well i pulled those suckers out as fast as i could, as hard as it was,as they were seized in place. Onl good place for them is in the panhard rod as they are more oil resistant and give a more positive steering feel.

I had polys on my disco and never busted one...

You mean to stick to the original rubber ones??

Is anyone running Sam's bushings....How long are they lasting

stick to the rubber bushes unles your only onroad use.

The Holey bushes from Sam are great for flex.
Mine are probably at the stage where most people would replace them (they dont hold the diff castor very well anymore) but ill keep running them (cause i not to fussed).
I got mine fitted about 9 months ago (wild guess) and have been out a shitload of times, easy average one day a week and sum full solid days offroad (80% of the time i am in my 4by its offroad).

At another wild guess i have done about 4000ks on them (i only ever drive my car to ormeau or the shops down the road).

hope that helps.

What makes the poly s unsuitable for off-roading??
I have always felt when used them in my disco that they offered much better road stability....

For added front flex is anyone supplying a hinged radius arm ?

they too stiff for offroad and flog out quick

if you search for the hindged radius arm you will find that they are not very friendly on side slopes. i wouldnt reccomend them at all.

Jay,
poly are sort of ok on the axle end of links.

DO NOT fit on chassy end as the bushe has very limited life.

fixed bush with the link moving stretches bush and poly does not like it for long, and also the transfer to much shock load into the mounts not good.

the only place where I've found urethane to work was using 'Super Pro' bushes on the chassis end of the lower rear trailing arms.
These ones are cleverely designed with a circumferal(sp?) groove and actually allow more flex than the OE rubber one, without the rear steer slop of the factory bush. Fulcrum/Super Pro are pretty particular about the durometer of their bushes as well.

Urethane just doesn't work where it has to rotate. As Grimace said, it flogs out really quickly. Ask anyone who's fitted polyurethane bushes in leaf spring eyes and shackles (I have on a Jeep). I went back to rubber extremely quickly as it worked better and lasted much longer.

Rangies and polybushes don't mix IMO.

Like all have mentioned, they work in very few places, but I hate them with a passion. I have them fitted to my friont shocks ATM and since it's such a shit of a job to do, I have left them in there for the time being.

Stick with rubber, you can't go wrong.

How much does a full set of rubber standard bushings cost compare to a poly ?
i can get a set of IRONMAN poly for $128 US here in Lebanon as a vendor has a set he wants to get rid of not very people in Lebanon run Rovers for off-roading (you see more TOY and Jeeps and stock Rover...)
