Z1 Motorsports Solid Differential Bushing Set

starstarstarstarstar 5/5 - (2 Reviews)
Fits models: 350Z / 370Z / G35 / G37 / Q60 2014-2016

Product Description

The large stock rubber fluid filled bushing in the rear subframe of 350Z, G35, 370Z, & G37 models is prone to failure. It is common to see evidence of the silicone fluid leaking out of the busted bushing characterized by black stains on the subframe below the bushing. The stock rear bushing is soft to isolate drivetrain vibrations, however performance is compromised especially after the bushing fails resulting in excessive differential movement reducing torque transfer and eventually causing a thud or knocking noise between shifts. The stock rear bushing is part of the rear subframe assembly and not available for purchase separately.

In addition to the rear bushing, there are smaller bushings in the front mount ears of the differential to secure it to the subframe assembly. The front bushings are not as prone to failure but can wear out due to excessive play after failure of the rear bushing. When these bushings wear out, the differential twists under load which can result in wheel hop, increased chassis vibration, damage to the rear differential cover, and excessive axle wear.

After several years of research, installing and comparing other solutions on the market, Z1 is now proud to offer a couple replacement solutions for rear differential bushings that we believe deliver the best in fitment and performance. Our aluminum differential bushing kit is intended for the hardcore enthusiast who is willing to compromise some drivetrain noise and vibration for maximum performance and the ultimate in torque transfer and control. We also offer Z1 Urethane Rear differential Bushings.

Z1 Motorsports differential bushings aren't just a repair item, they're an essential upgrade for enthusiasts from daily drivers to the weekend track warrior. Z1 bushings are engineered to provide the user with a product that fits like OEM at a fraction of the price while maintaining the highest level of performance. The end result is a car that is more pleasurable to drive with precise shifts and predictable control.  

Includes:

  • (1) Rear Differential Bushing
  • (2) Front Differential Bushing - Top (Diff Nose)
  • (2) Front Differential Bushings - Rear (Diff Nose)
  • (1) Differential bushing Installation Tool (Optional)

These solid bushings are great.! I love them c: I have had them on my G35 for a few monthe now. It made the car a lot more responsive by tightening up everything around the diff. The do chatter a bit, but f#@$ it race car lol. Honestly it's not theat bad though. I can live with it. I think most people could also if you really care about performance. I mostly have music on all the time as I drive so honestly I never hear it.

I've had the solid mounts for several months and has reduced the wheelhop in my 350z. These solid bushing do cause a mild increase in the drivetrain noise, but I'm went with this option since my 350z is a non daily driver. I strongly recommend these solid bushings for anyone who is a hardcore car enthusiasts like me and looking for that instant torque transfer.
