The SuperPro forward pinion differential mount bushing kit for 2011 Chrysler 300 (and shared Charger/Challenger platforms) upgrades the factory forward differential mounting points that wear under heavy loads. It provides a firmer mounting of the rear differential to increase traction, reduce cabin impacts and control differential movement during throttle changes. The kit extends service life and is backed by SuperPro's lifetime warranty for long‑term durability.
