Tighten up your Gen 3 HEMI drivetrain with the JXB Performance Driveshaft Center Support Bearing Carrier Upgrade CHR01A0. The factory center support uses a thin rubber section to isolate noise and vibration, but that soft construction also allows the center bearing to move away from its ideal position when the drivetrain is loaded. As the factory rubber ages, it can sag, crack, and deteriorate, further affecting driveshaft alignment and introducing unwanted movement during launches, shifts, and quick throttle inputs. JXB’s upgraded carrier holds the bearing securely in position, helping maintain driveshaft alignment and deliver more direct torque transfer.

The improvement becomes especially valuable on high-output Gen 3 HEMI applications. Whether you’re driving a naturally aspirated Scat Pack or putting significantly more power through a modified Hellcat, movement in the driveshaft carrier can make the drivetrain feel less precise. By reducing that movement, the JXB carrier can provide more direct throttle response, firmer shifts, more immediate launches, and smoother low-speed throttle transitions. It may also reduce vibration caused by driveshaft misalignment or deterioration of the original rubber support.

JXB offers the carrier with Street and Track bushing options. Both are significantly stiffer than the factory support, but the Track bushings are approximately twice the stiffness of the Street version. Street bushings are recommended for most street-driven cars because they provide increased drivetrain control while offering greater isolation from noise, vibration, and harshness. Track bushings are intended for enthusiasts who prioritize maximum support, while the available “Both” option lets you experiment with Street, Track, or mixed bushing combinations.

Installation is simplified by JXB’s two-piece carrier design. The driveshaft itself does not need to be removed or disassembled because the new carrier clamps around the existing OEM center bearing. The original carrier must be cut away, so installation does require a cutting tool along with access to the center bearing area. Depending on the vehicle, exhaust components, heat shields, braces, or splash shields may also need to be removed or lowered for access.

Fitment covers 2015-2023 Dodge Charger, Dodge Challenger, and Chrysler 300 models, including RWD and AWD configurations, V6 and V8 engines, automatic and manual transmissions, and all trim levels. That broad compatibility makes CHR01A0 useful for everything from factory street cars to modified Gen 3 HEMI performance builds. For owners looking to address an aging factory carrier or strengthen the drivetrain before adding more power, the JXB Performance carrier provides a purpose-built solution without requiring driveshaft disassembly.
