Product Description

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.

Includes your choice of the following:
Z1 Urethane, Whiteline, Z1 Solid, or SPL Front and Rear Differential Bushings
3 Liters of Red Line or Motul 75w90 or Motul 75w140 Differential Fluid
Z1 High Capacity Differential Cover with Mounting Stud and Breather Tube
1 Tube Ultra Gray Silicone

Still hearing little clunking noises but I’m sure that’s in my end. Other than that the driving experience was enhanced so it feels and drives great! Only issue I ever had with this kit was that I couldn’t get the rear diff bushing housing out I needed to use a torch and a big impact gun even with the removal tool so yeah but after that it was totally worth it! Definitely do recommend this but be ready to struggle with the old bushing on the subframe

Great kit! Fitment was tight & took a while to install. May require slight modification if running the Shockwave exhaust.

Car feels much more planted on the road. You can really feel the tires dig in under acceleration. Turn in feels sharper as well as corner exit when getting on throttle. Definitely pair with the subframe collars and brace to really up the handling response. Can't wait to start adding some power now.

Great quality. ***FYI*** If you are running a Greddy single exit exhaust you WILL have to cut down the fins on the right side of the diff cover to get clearance!

I just installed this kit with the Z1 urethane differential bushings and let me say WOW what a difference, in the way the cars power feels planted to the ground with a drive system and no more jerky/shaky low speed low gear parking lot drives anymore. Thank you Z1!! I highly recommend the urethane diff bushings from Z1.

Couldn’t be happier with my z1 rear diff kit on my G37x sedan! Went with whiteline bushings, also the bell raceworks diff brace now fits the finned covers! Not running a cooler, performed very well on track and daily driving. Must have when I did vlsd swap!

Recently installed this kit with the Z1 urathane bushings and motul oil. The bushings made a huge difference! Even from when the factory bushing was good the Z1 bushing is so much better. Practically eliminated wheel hop and totally holds better through corners. I'm very happy with the kit! Not an easy install due to taking off the old one but after you get it out the new bushing fits in easy. The high capacity cover looks awesome as well and has is perfect fit with stock exhaust.

Z1 differential cover is a real treat for my RWD ride it improve performance from oem factory cover. The bushings from ES are not the best but do the trick. Price on the complete kit is on point. Big savings if where to buy separate. In the future and when the bushings go bad I will buy Z1 bushing kit that blue color is something else. I do recommend this kit to anyone who drives a z or a g as they need to be replaced when needed.
