Stage 2 Suspension Upgrade Kit

The Mopar Suspension Upgrade Kit is a Stage 2 performance package that upgrades your vehicle to Super Track Pack specifications. This comprehensive kit replaces factory components with performance-tuned springs and Bilstein shock absorbers, resulting in improved handling and a ride height reduction of up to 0.5 inches depending on the specific vehicle configuration. The kit includes front and rear springs, front and rear shock absorbers, rear upper isolators, a rear top mount, front upper isolators, front jounce bumpers, and rear lower isolators. Compatibility is strictly limited to certain RWD vehicles and is not compatible with all trims. For Chrysler 300, it fits RWD and non-SRT models but does not fit vehicles with sales code SER. For Dodge Charger, it fits non-SRT vehicles but is not compatible with sales codes SMC or SER. It fits Challenger RWD models. Additionally, the kit is intended for 3.6L and 5.7L vehicles that are not already equipped with the Super Track Pack option, and it is not for Scat Pack models. Installation on 2008-2010 model years requires specific hardware modifications: you must shim the front shock opening using 14mm ID washers and install a longer M14 x 2 x 110mm bolt to accommodate the wider shock opening.
