Rubber Sub-Frame Bushings?

67 Camaro

Did quite a bit of search topic reading on this

Checking off another "to do" item. Current sub frame bushings are original and I want rubber one to replace them.

Looking at OER bushing & bolt kits

Is there another rubber kit that is better quality rubber??

Re: Rubber Sub-Frame Bushings?

I did mine some years ago....at around 5-10 years were shot. Ended up going DSE solid aluminum....I would suggest aluminum OR poly mounts

Re: Rubber Sub-Frame Bushings?

Given the original rubbers have lasted 52 years, granted they are cracked and flatter than when new, they certainly were still good after "5-10" years of use and frankly even at 52 years old are still in tack but obviously have succumbed to age and are flatter and harder than when new

I am familiar with Poly mounts but prefer rubber which is what I have replaced them with on my other car and after 10 years they are still good with no signs of cracking

Given these cars are "fair weather" garaged cars and the 67 was a CA & AZ car its whole life is likely why they have lasted as long as they have

Was looking for those who put rubber in and if any other brand than OER offers any better rubber quality. Not saying OER is inferior, just asking if there is other options for rubber that people have used

Re: Rubber Sub-Frame Bushings?

I installed a set of OER rubber bushings from Classic Industries about 18 years ago. They're still holding up well on my garaged CA car.

Re: Rubber Sub-Frame Bushings?

I bought ones that were GM Restoration parts around 6 years ago. No issues with them and they come with a lifetime warranty. I think I found them on sale on Ebay.

Re: Rubber Sub-Frame Bushings?

Like Doug, I used alum bushings and never looked back. I did leave the rad support rubber.
Suggestion: when bolting together, use plenty of antiseize on the threads for future movement.

Roger, IIRC I bought mine from Camaro Central. I think they were CHQ (Classic Headquarters).

I like poly or better yet delrin bushings.

My 5-10 year old ones that replaced the 40 or so year old ones looked as bad as the ones they replaced and you could break off chunks. (Not 100% sure if OER or ?)
Car is a "fair weather" car, might see 1000 miles a year, and kept in a garage.
When jacking the front up, the fender gap would open up at the rocker and touch at the top door corners.....not good.


DSE aluminum solids... problem gone.

Re: Rubber Sub-Frame Bushings?

What is the TQ for Body bushing bolts:

Radiator Support?
Middle sub frame?
Rear sub frame?

This is found in your Chassis Service manual.

Thanks...after looking through sections 2,3, 11 & Specifications I must have missed it. Could not find anything for sub-frame TQ specs

That's the first place I looked...and yes it appears well hidden. "my" Chassis Service Manual, for section 2 (Frames) is only 4 pages long (163-166) and has zero TQ 411 for anything

Perhaps I don't have the right Chassis Service Manual (one on right in pic)
