Product Description

The RS-R Down Sus Springs (Part T278D) are precision-engineered lowering springs designed for the 2010-2015 Lexus RX350 with all-wheel drive. These springs reduce the vehicle's ride height by roughly 25-30 mm (about 1.0"-1.2") at both front and rear to create a more aggressive stance while preserving ride comfort. Built with consideration for the factory suspension geometry and spring rates, they seamlessly integrate with OEM shocks and mounting components to improve handling and reduce body roll without harsh ride quality.

Finished in a durable powder coat to resist corrosion and wear, the RS-R Down Sus Springs enhance both appearance and performance for Lexus RX350 owners who want a lowered look and improved dynamics on street driving. Backed by a manufacturer warranty, these springs offer a balanced upgrade that enhances confidence in cornering while maintaining everyday drivability.
