JXB Performance - Subaru Impreza/WRX/STI 3rd/4th/5th/6th Gen Driveshaft Center Support Bearing Carrier Upgrade (SUB01A0)

The JXB Performance carrier upgrade eliminates drivetrain slop and maintains proper driveshaft alignment under load. By securing the center support bearing without needing to remove the driveshaft, it improves throttle response, provides crisper shifts, and allows for quicker launches without added vibration. The Problem The stock Subaru/Saab center support bearing carrier is supported by thin rubber that allows the driveshaft to deflect under heavy load. This deflection creates "slop" in the drivetrain, sags over time, and causes unwanted misalignment, making the car feel less responsive. The Solution The JXB Performance Driveshaft Carrier Upgrade clamps directly around your existing unserviceable bearing. Its two-piece, hinged design means you do not need to remove or disassemble the driveshaft to install it. Key Benefits Improved Drivability: Experience more direct throttle response, firmer shifts, and smoother low-speed on/off throttle transitions. No Added NVH: Built-in isolation dampers minimize noise, vibration, and harshness (NVH) so your daily drive remains quiet and comfortable. Maintained Alignment: Keeps the driveshaft securely centered to prevent premature wear on the bearing and carrier. Customizable Feel: Swap between street and track bushings depending on your driving style (Track bushings offer a more rigid connection).
