05-10 LX Platform Differ ential Kit Bushings

The 05-10 LX Platform Differential Kit Bushings from Prothane are engineered polyurethane replacement components designed to eliminate the compliance and deterioration found in factory rubber differential housing mounts. As a mechanic, you know that OEM differential bushings degrade over time, introducing unwanted movement and noise into the drivetrain—especially under hard acceleration or cornering loads. These bushings restore rigidity to the differential mounting points, reducing deflection and improving power transfer consistency across 2005–2010 Chrysler 300C, Dodge Challenger, and Dodge Charger platforms.

Prothane's polyurethane construction combines durability with controlled flex, offering superior performance over both aged rubber and overly rigid solid mounts. The black polyurethane material resists UV degradation and maintains elasticity across a wide temperature range, while the cadmium-plated steel components resist corrosion in underbody environments. This kit-based approach ensures a complete bushing set for the differential housing, eliminating the need to source multiple individual components. The compact 6.2 x 4.1 x 6.3-inch package weighs just 1.8 lbs, making installation straightforward for anyone with basic suspension and drivetrain experience.

Enthusiasts running modified 300C, Challenger, or Charger builds benefit most from this upgrade, as polyurethane bushings significantly reduce axle hop and wheel hop during aggressive launches or track use. Street drivers will notice tighter, more predictable handling and a noticeable reduction in clunking or rattling from the rear axle assembly. Installation requires basic hand tools and takes approximately 1–2 hours, with no welding or fabrication needed. Compatibility is confirmed for 2008–2014 Chrysler 300C, Dodge Challenger, and Dodge Charger models on the LX platform, making this an essential upgrade for any serious modification or restoration project on these chassis.
