Takes of play in original differential bushing

Installed this in a 2005 GTO. It slipped right into place. I installed this along with the whiteline rear sub-frame bushings.
Great Value

The install is difficult without a press but once installed the insert is nice and snug. I had to get creative with my floor jack and truck frame rail to get the insert in. The biggest difference I've noticed is my on/off throttle response. Before the insert I used to get a clunk in the driveline which is now almost completely gone when getting on/off the gas at cruising speeds.
Good upgrade for the price!

You can either get this, or the Harrop diff cover for about $570 and still receive about 60-70% of the performance benefit. Definitely tightened up the rear and a good buy from a good company.

A little hard to install, but well worth it.
