The large stock rubber fluid-filled bushing in the rear subframe of the 2023+ Z, 350Z, G35, 370Z, & G37 models is prone to failure. It is common to see evidence of 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 the 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 replacement solutions for rear differential bushings that deliver the best in fitment and performance. Due to some problems we have experienced with other products we have specified a high-temperature urethane formulation to prevent the bushing from deterioration under extreme heat often experienced on the track. The Z1 bushing is the optimal length to fill the hole in the rear subframe in order to provide the most contact area while not protruding out the ends. Our bushing includes a press-in steel sleeve that locks the urethane securely in place without the need to remove the existing stock steel sleeve from the original bushing. We also offer a Z1 solid aluminum rear differential bushing set for enthusiasts willing to trade some drivetrain noise and vibration for torque transfer and control.
Z1 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.
