05-10 LX Platform Rear Sway Bar Bushing Kit

The 05-10 LX Platform Rear Sway Bar Bushing Kit (Part #4-1139-BL) is a direct replacement suspension component engineered for 2005–2010 Chrysler 300C, Dodge Challenger, and Dodge Charger models. This kit restores lateral stability in the rear suspension by replacing worn or degraded bushings that connect the sway bar to the chassis, a critical interface for cornering stiffness and body roll control.

The kit features a 0.688-inch bar diameter with polyurethane and steel construction, finished in black with cadmium plating for corrosion resistance. Greasable design allows field maintenance without complete disassembly, extending service life in harsh driving conditions. Polyurethane material offers better longevity and vibration isolation compared to original rubber bushings, particularly in performance or heavy-duty driving scenarios where suspension articulation is frequent.

This kit is essential for owners addressing suspension wear, improving handling response, or completing a rear suspension rebuild. Worn sway bar bushings manifest as increased understeer, reduced cornering precision, and clunking sounds during lateral suspension movement. The 05-10 LX platform rear sway bar bushing kit fits the full-size Chrysler LX lineup, making it a direct bolt-in replacement for OEM components in that generation range.

Rear sway bar bushings experience constant flexing and compression, making them susceptible to cracking and hardening over time. Upgrading to polyurethane improves durability while maintaining suspension geometry accuracy. This rear sway bar bushing kit delivers the geometry and compliance tuning critical for LX platform owners seeking reliable, street-proven suspension performance.
