Product Description

The RS-R Down Sus Lowering Springs (Part T284D) are engineered specifically for the 2001-2006 Lexus LS430 (UCF30/31) with rear-wheel drive. These springs deliver a mild drop that improves the vehicle's stance and handling while maintaining a comfortable ride quality. Designed around the factory suspension geometry and spring rates, the RS-R Down Sus set enhances grip through corners and reduces body roll without compromising daily driving comfort.

Drop height varies slightly between early and later model years, with the 2001-2003 LS430s dropping more aggressively compared to 2004-2006 models. RS-R's precision-wound springs and corrosion-resistant powder-coated finish ensure long-lasting performance while fitting directly to OEM shock absorbers and mounting points. These springs are ideal for LS430 owners looking to refine their sedan's look and improve road manners without sacrificing smooth ride characteristics.
