Show original supplier description

The Factory CH3RB is a rear suspension conversion kit designed as a permanent solution for 2005-2016 Chrysler 300 RWD vehicles experiencing issues with their factory "self-leveling" rear suspension. When age and mileage cause these high-cost factory units to wear out, the rear of the vehicle may sit too low, leading to a rough ride, especially when loaded with cargo or passengers. Other reported problems include a bouncy ride on uneven surfaces and unexplained noises from the rear suspension. This kit replaces the worn-out air suspension components with premium steel coil springs capable of handling the load, paired with custom-tuned shock absorbers. This combination aims to restore a smooth and level ride quality, utilizing Strutmasters' patented Glide Ride Technology. The kit is designed for a perfect fit and easy installation, with an included manual and videos to guide the process in 8 simple steps. It is compatible with the OEM numbers 5181546AH, 5181546AD, 5181546AE, 5181546AF, 5181546AG, 5181545AH, 5181545AD, 5181545AE, 5181545AF, and 5181545AG. The product comes with a 1-year warranty on shocks, struts, and springs, and Strutmasters offers hassle-free returns within 30 days.
