Z1's full differential kit includes everything you need to upgrade and update your rear driveline. If you are going to remove the differential it only makes sense to do it once.

With the Z1 kit you have new differential bushings, a High Capacity Z1 Differential Cover, and the best oil on the market. We even include a tube of ultra gray so that you have everything but the tools to complete the job.

When the stock rear differential bushing fails you start to experiance wheel hop under hard acceleration. This also puts excessive strain on the driveshaft U-Joints, and axle shafts. By upgrading to the urethane bushings you stiffen up the rear end to handle harder launches and smoother shifts. Plus with the upgraded fluid you don't have to worry about oil breakdown at higher temperatures.

Don't skimp out; do the entire kit with Z1.

*This kit can not be used on G35 models equipped with 4 Wheel Steering.
