Bell Raceworks 350Z G35 Differential Cover Brace

The Bell Raceworks 370Z / G37 Rear Differential Brace provides additional support of the differential in your Z or G, maintaining rigidity as you use and abuse your car.

The R200 rear differential in your G37 or 370Z is mounted to the subframe with a single stud. For most this is sufficient however hard clutch kicks, hard launches, and hard shifts from sporty driving all put tremendous strain on the single stud somtimes leading to faliure. The Bell Raceworks Differential Brace provides additional support using a hole already drilled in the inside of the rear subframe. The additional support reduces strain on the differential cover and stud while simultaneously aiding in the reduction of wheel hop and driveline slop. Made specifically to fit the Z1 High Capacity Differential Cover, this brace bolts directly to the rear differential with supplied hardware. 

Installation of this brace may require partial removal of the rear differential. Included hardware will be installed in the cavity above the inside of the RH (passenger) spring bucket, we've found the best method of installing this hardware is by using a ratcheting wrench with a swivel head. This method is easiest if the brace is loosly mounted to the rear differential first, and tightened on the subframe side LAST.

Installation Note: Because this brace is mounted directly to the subframe and differential, users with stock differential bushings or urethane differential bushings (like the Z1 Urethane Rear Differential Bushings) may notice additional NVH. (Noise, Vibration, Harshness)
