Alloy or Teflon

[brad3000]

G,day All,the past few weeks iv been doing a bit more research on the whole suspension thing,im going 2 inch springs and a 2 inch body lift.iv had my disco up on the forklift at work having a real good look at whats got to be done for the body lift,alot of the lift blocks you buy in the kits are Alloy or steel,but cost alot to buy,i cut some 2 inch (long) x 70mm (round) solid teflon blocks at work and they were FREE....do you think teflon will be ok for the job????,its such a hard type of plastic and took some time to cut all the 10 blocks,i thought it would be fine,but the opinion of all you guys has always really helped me, cheers Brad

teflons not teflon, just like steels aint steels.


teflon comes in different grades when you purchase it as a bar stock item.

if the manufacturers spec indicates that its a non deforming heat and oil resistant version your laughing.

BUT without looking for hours at the RTA site I think its illegal in NSW anyway.
I believe must be steel or aluminium.

most of the poly blocks I have seen have a crush tube through the centre to increase its strength.

I wouldnt be using any straight poly blocks without the crush tube. Others say that ally/steel blocks can 'feel' a bit hard, depends on how you mount them I suppose

FYI

yeah, I dont know.

The only thing I can think of is of they remove the original rubber mounts and just use the steel spacers. Then you probably would get some 'harshness' as the body wouldnt have any give to the chassis.

I dont know why you would do that, but some may :(

Double ????
The lift blocks are spacers only to reposition the body Vs the chassis. they still have the rubber body mounts installed on them so the result should be identical.
Look at the last Pajero with chassis. They lifted it compared to the previous model by adding steel spacers.
If I were adding spacers I think I would use steel and weld them to the old mounts. That is what Bitsa****ty did.
I know the bloke with the yellow 2door from Narrabeen who had 4 inch spacers had to weld side braces onto the chassis outriggers before the engineer would pass it. Thats why I do not think Teflon is suitable . The side thrust could cause teflon to compress side to side and this may bend/fatigue the through bolt.

Teflon, regardless suffers from Cold Flow...

Industrial Nylons would be OK for small lifts.. Eg Ertalon 6PLA or Ertalon 6XAU...

But never a PTFE regardless of whether it be Virgin, Bronze, Carbon etc..


BTW - You must have a nice boss to let you cut up about a $1000.00 dollars worth of PTFE rod :cool:
