But you own a 130 so it could happen any way

only if the durometer of the bush is greater than an OE rubber one.
The design of the bush has a lot to do with it too. If you look at the photos check out the circumferential groove in one of them. That one goes on the back side of the radius arm/chassis mount. It allows more flex in the bush.
The lower rear trailing arm/chassis mount bush from Super Pro also has a similar design on both sides of the mount, allowing more flex and less stress on the chassis mount than an OE rubber one.

Gday rick

Mate im in the same process those bushes look like supa pros am i right if so were bouts did ya get em as this looks like what i should use all round as my rear links at the diff dont last long as the std rubber jobbies flog out quick also my swaybar bushes are a 12 monthly change over so might be beta doin the whole truck in polly like disco white has done and just keep the rubber in the shocks which im about to change anyways

I saw them up at Supercheap this afternoon. No doubt they'll be able to get in the correct ones. I bought my shock ones from 4WD1 in Castle Hill - they post.

I have used the red type years ago and never agian but then there was literally only 1 or 2 brands to choose from. Looks like the softer type may actually work without destroying the ride or your suspension components.
After i decided to the poly's from my rangie it was an oxy and grinder job to actually get the f$ckers out.

colour means nothing, it just depends on what colour they tip into the mix when they mould them.

Yep been there done that there a bastard to get back out

Back in the late 80's dad and i fitted polly to his stage 1 one of his mates had turned up some polly bushes from yellow polly and it was friggin hard as we had to make up a special puller to fit them and do then in 2 bits one each side and those f@rkers are still in there and just as good as the day they were fitted these are the best shackel pin bushes ive ever seen
