Brutal, Ok, I can see that, as they are much harder rubber and 2 tons of car is going up and down in a small space. Even if the bushing is round, most of the weight will be at the top. Do you assemble with any kind of grease of silicone coating?

Wayne,

I just looked at the written instructions included in the poly shock mount kit from Welsh Enterprises. Here are the full instructions:


1. Remove old shock mount assembly from your XK8.

2. Using a 3/16-inch drill bit, drill out the rivets of the shock plate, and remove the old rubber bushings.

3. Prepare shock plates by removing any old material stuck to them, and clean the surface thoroughly.

4. Lubricate shock plates with a silicone-based lubricant (important that it is NOT petroleum-based).

5. Place both small urethane bushings in the center of the mount.

6. Place shock plate on top of the bushings.

7. Install new washers and bolts, making sure to tighten evenly until bushings are compressed.

8. When compressed, install new rivets.

9. Remove nuts and washers.

10. Install large urethane bushing and shock mount top cover.

11. Re-install shock mount assembly on your XK8.

 

Jon, That's the way I see it. I'm just seeing is something can be done to make it even better.
Brutal is not a fan, but I do believe they will outlast us, well me anyway.

Thanks Jon for providing the printed instructions. We used a Silicone Spray vs a Paste. Most poly bushing kits come with a package of lube to use on install. Wire brush on table grinder will clean the plates and the center metal cyl. that slips over the shock shaft.. I've used Poly Bushings on my off-road 75 Bronco (owned 10-12 yrs) and over 120K miles on my modified MGB ( owned 12 yrs). Nary a problem with deterioration.
