I would like to change all my suspension bushings and sway bar bushings over to 1le. Does any body know the GM part numbers?
thanks

The 1LE 36 mm front and 24 mm rear bushings are as follows: 14094389 and 10037104. The poly end links are 10221779.

Cool thanks for the info. How about the front and rear control arm bushings? Do 1LE's have diferent ones then the WS6. If so, can I get those part numbers to.

I believe the LCA bushings were, like the sway bar bushings, a higher durometer rubber, but beyond that, I can't be of help.

As far as I can tell, thirdgen 1LE's used most of the same suspension components as the WS6 cars, which your car already has. That being said and assumed try, GM does not sell just the bushings for the LCA's seperately, they only sell the assembled arm. Try 10164151 for the rear LCA, it's a fourthgen part # but is a direct bolt in to the thirdgen. SLP sells them cheaper than GM does.

Thanks 98_1le, I have those control arm now on order. My next question is what about the front control arms. Did they use the WS6 front control arm bushings in the 1LE?

The swaybar bushings are not always 36mm front and 24mm rear for the WS6, as stated in the sales books. I actually measured mine and they are 34mm front and 23mm rear. What might be the GM part numbers for these? Another question is, what's the actual size of the 1LE bars?

The hollow 1LE front stabilzer bar is 36 mm--GM part # 14094344. The rear is 24 mm, GM part # 10035033. These were on some, but not all, Camaros from 89-92 and on some, but not all, Firebirds, 86-92. I'm afraid I have no part #s for the smaller bars.

I just measured my front bar, where the bushings are, with a caliper. It measures 1.41" or 36mm. I guess I'll order the 36mm bushing p/n you gave above. I also found out there was never a 23mm rear bar on a third gen. I bet if I pull down that bar it will measure 24mm. Thanks
