Stern Solid Rear Diff Mount (Power Ring), B4/B5 Chassis

This insert is designed as an upgrade for the factory differential mount. It installs quickly and easily and helps prevent the common differential ";clunk"; associated with higher horsepower vehicles. For the Audi B4 (90 Quattro, RS2) chassis, and all Audi B5 (A4, S4, RS4) models. This Rear Differential Mount takes only 15-minutes to install.

It is designed to completely eliminate excessive rear differential movement and cure the dreaded "clunk" caused by aggressive shifting and/or acceleration. This is a must-have upgrade for race oriented vehicles looking or a completely solid front diff mount.

For best performance, use with our 034 mounts and Stern rear diff bushings for a complete, locked down drivetrain solution.

Great value! Installed in less than 40 minutes and I am no mechanic. The difference is noticeable- I installed with Stern rear diff bushings. Don't believe the rumors that there's increased noise, I have zero. My wife even likes it better. Review by Hector (Posted on 9/23/2009)
I was really impressed by the Stern Power Ring. It is worth $50 bucks. Gets rid of alot of the drive train movement. Almost gets rid of the "clunk", however i still get it once in awhile. Review by David (Posted on 9/5/2009)
