Tighten Up a Sloppy Rear Sway Bar Mount
The factory rear sway bar mount bushings on the Challenger and Charger wear out and allow the bar to shift under load, softening rear roll control and introducing clunks over bumps. This Whiteline W23331 rear sway bar mount bushing kit is sized for an 18mm bar and uses internal bore knurling with grease retention lips to keep the mount tight and consistently lubricated.
