Charger Challenger 300 Driveshaft Center Support Bearing Carrier Upgrade

The Driveshaft Carrier the LX and LD Platform Should Have Come With

The JXB Performance CHR02A0 is a billet aluminum driveshaft center support bearing carrier upgrade for the 2005-2014 Dodge Charger, Challenger, and Magnum plus the 2006-2014 Chrysler 300. The CHR02A0 replaces the factory rubber-mounted carrier that holds the driveshaft in place with only enough strength to move off-center under approximately 20 pounds of force. Under high-torque launches, aggressive shifts, and repeated load-cycling, the OEM rubber bushing allows the driveshaft to deflect off-axis, contributing to driveline vibration, clunking, and accelerated bearing wear. Over time the stock rubber dries out and cracks, typically within 5 to 10 years even on well-maintained cars, and when it fails the center bearing loses proper alignment entirely. The CHR02A0 solves this with a precision-machined aluminum carrier and custom polyurethane isolator bushings that keep the driveshaft locked on center under any load. Two bushing durometers are available: Street for a quieter daily-driver experience and Track for maximum rigidity with no-compromise driveline performance. Both options are interchangeable on the same carrier, so owners can switch between them as their use case changes. The CHR02A0 is a direct bolt-on replacement requiring no modifications, using vehicle-specific hardware with published torque specifications for a clean, repeatable install.

Key Features

• Precision-machined billet aluminum carrier replaces the factory rubber-molded plastic unit
• Custom polyurethane isolator bushings available in Street (soft/quieter) and Track (hard/louder) durometers
• Street bushing absorbs most driveline NVH; a light hum may be present at certain speeds
• Track bushing provides maximum driveline rigidity with minimal compliance; increased cabin noise expected
• Both bushing options are interchangeable on the same carrier so you can swap without buying a new unit
• Prevents driveshaft off-center deflection under high torque, launches, and aggressive throttle transitions
• Eliminates common driveshaft clunk, shudder, and vibration caused by a worn or collapsed OEM bushing
• Direct bolt-on installation; no modifications or special tools required
• Made in the United States
• Fits 2005-2014 LX and LD generation Charger, Challenger, Magnum, and Chrysler 300

Frequently Asked Questions

The Street bushing is a softer durometer polyurethane that isolates most driveline NVH from the cabin. A faint soft hum may be audible at certain speeds, but most drivers will not notice it with windows up or any exhaust installed. The Track bushing is a stiffer durometer for maximum driveshaft rigidity with zero compliance. It can introduce significant cabin noise and is intended for dedicated track or drag applications where performance takes priority over comfort. Both bushings fit the same carrier and can be swapped at any time.

No. This carrier is engineered specifically for the pre-facelift 2005-2014 LX and LD generation driveshaft architecture. The 2015 and newer facelift generation uses a different driveshaft and carrier geometry. JXB Performance makes a separate part, CHR01A0, for the 2015+ generation. Both variants are available as options on this listing.

In many cases, yes. Driveshaft clunking and vibration on these platforms is frequently caused by a collapsed or cracked OEM center support bearing bushing that allows the driveshaft to move off-axis under load. This upgrade eliminates that bushing compliance entirely. If the center bearing itself has failed or the driveshaft has other damage, those components will need to be addressed separately.

Yes. The Dodge Magnum (2005-2008) uses the same LX-platform driveshaft architecture as the Charger and Challenger from that era. All Magnum trims including SE, SXT, R/T, and SRT8 are a direct fit.

This carrier covers the 2005-2014 generation, which includes SRT8 variants on that platform. For 2015+ Hellcat, Scat Pack, Redeye, and Jailbreak models, use the CHR01A0 variant listed here. Both are designed to handle the torque output of these engines and are commonly installed on high-horsepower builds.

Torque the two bolts that hold the carrier halves together to 20 Nm. Torque the bolts that attach the carrier assembly to the vehicle to 14 Nm. Blue or red thread locker is recommended on all bolts to prevent loosening from driveline vibration.

Not necessarily. This is a carrier upgrade; it does not include the bearing itself. If the center support bearing is in good condition, it presses into the new JXB carrier. If the bearing is worn, noisy, or has play, it should be replaced at the same time before installing the new carrier.

Most experienced DIY installers complete this job in under an hour with the vehicle on jack stands. No specialized tools are required beyond standard hand tools and a torque wrench. A lift makes the job easier but is not required.

With the Street bushing installed, most drivers experience minimal or no increase in cabin noise. A faint soft hum may be present at specific RPM or speed ranges, particularly with the windows down or on a very quiet exhaust. With the Track bushing, cabin noise can be substantially higher and is not recommended for daily street use.

Yes, it is a direct bolt-on replacement. It uses the same mounting points as the factory carrier with no cutting, drilling, or bracket fabrication required. The kit includes all necessary hardware and installs with standard tools.

Installation Notes

1. Safely lift and support the vehicle on jack stands at the recommended lift points.
2. Support the driveshaft before unbolting the center support carrier to prevent stress on the front and rear CV joints.
3. Remove the two bolts securing the OEM center support bearing carrier to the vehicle tunnel.
4. Lower the carrier assembly and press out the center support bearing from the OEM carrier.
5. Inspect the center support bearing for wear, play, or noise; replace if needed before continuing.
6. Press the center support bearing into the new JXB Performance carrier using a suitable press or bearing installation tool.
7. Install the polyurethane bushing set into the carrier halves per the included instructions.
8. Assemble the two carrier halves around the bearing and torque the carrier half bolts to 20 Nm with blue or red thread locker applied.
9. Position the assembled carrier in the vehicle tunnel and torque the mounting bolts to 14 Nm with thread locker applied.
10. Reinstall the driveshaft support and lower the vehicle.
11. Road test and verify smooth, vibration-free operation through a full range of acceleration and deceleration.
