These bushings firm up the rear differential subframe with respect to the chassis of the car, reducing or eliminating the dreaded rear diff thump on hard acceleration. The polyurethane Kartboy pieces insert into the stock bushings to make a firmer connection of the subframe to the chassis. The result is better control of the rear differential and rear suspension under cornering, acceleration, and braking.
Available in two different hardnesses -- Comfort is firm but not brutal, while Race is pretty darned hard.

Easy enough to install. Did the Turn In Concepts diff support bushings in Race/Hard material at the same time. Definitely reduced some drivetrain clunk and slop, and did increase NVH as warned, but mostly as a higher pitched gear whine around 60-65 mph. I’m not upset or terribly surprised, but would probably do the softer “comfort” material if I were to do it again, as this is my daily that only occasionally sees track use.

Had a knocking noise coming from the rear of my car, found a worn bushing and replaced with the kartboy rear diff outrigger bushing and the knocking is gone. Quick and easy install, I do recommend using some heat to get the three bolts out holding in the bushing especially if rusty.
