There is nothing integral to the design of our Poly Differential bushings that causes a variance of NVH from part to part. So you can not take this as "there MAY be some noise." I am only saying that because customer opinions vary, we are keeping our current kit, which is a great product and has the best performance, and also offering a softer durometer option for customers. Thats all.

cool thanks!

Have you seen increased torque off the line with the 4.10 rear? I am thinking about getting a bunch of mods and that is the first thing that I was recommended to do before I put in the supercharger and other HP boosters. Is it worth the upgrade, or is the 3.45 good enough with the increased HP?

Approximately 2 weeks.

So did you isolate the cause of the noise to be your pinion lash setting?

if you're getting a supercharger, I'd stick with the 3.45's...traction will too much of a bitch with 4.10s + boost.

I agree completely. It's hard enough to get traction with the 3.45's and my Vortech.

Just received the Pontiac G8 bushings they are exact outside diameter,as you can see in the pictures the isolators appear to be a little less forgiving with movement compared to the stock bushings,I will get back soon with pictures on how I stiffen them up.

i think pedders makes inserts for the factory bushings to help stiffen them up

The inserts i believe are for the sub frame bushings not the diff bushings,But I could be wrong.

So BUMBLEB, are you saying that the factory G8 bushings appear stiffer than the factory Camaro bushings? That would make them an inexpensive upgrade for people who are not interested in a poly bushing if you are correct.

Yes most defiantly as you can see they defiantly look stiffer I dont know if you can tell by the pictures as you can see the old one out of the camaro their is allot more gap between the cavities and side wall.I will have some pics later today on how I will stiffen them up.

How very intriguing. I love learnig things like this.

I used aluminum 1/4 dowel on the sides and after i install bushings in differential I will then drive the 3/8 dowel top and bottom,This should work perfect,Great sound dampening and nice and stiff.
