Want to tighten up the diff on your 2021+ G8X M3/M4 and help eliminate any extra diff movement on hard launches? We got you covered with our Billet diff inserts. They are machined from 6061-T6, and anodized black for a long-lasting finish. They install easily by removing the diff bolts one at a time, inserting the bushing, then retorquing each diff bolt. They are sold in pairs of 4.

Kit includes:

4 G8X Billet Diff bushing inserts
Please note: Slight increase in NVH may be noticed from this product as it stiffens up the rear end, and removes some of the sound dampening of the rubber bushings
