Want to tighten up the diff on your 2021+ G8X M3/M4, A9X Supra, G42 2 Series, or G2X BMW and help eliminate any extra diff movement on hard launches? We got you covered with our Rear Billet diff insert kit. This is pressed into the factory bushing and fills the voids in the bushing. This keeps the stock bushing ride compliance but removes any unwanted movement. These are sold as a kit. To install remove the rear diff bushing, use the stock bolt in press the bushing in, and then replace it with the new bolt washer, and lock nut!
Kit includes:
- One Billet Bushing insert
- Two 46mm Hardened Steel Washers
- One 12.9 M14 Bolt
- One M14 Lock nut
THIS KIT MAY REQUIRE LOWERING OF THE SUBFRAME TO GET THE STOCK BOLT OUT, AND THE NEW ONE IN
Please note: A 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
