Product Details
These RS-R Super Down Sus springs fit the 2001-2006 Lexus LS430 (UCF30/UFC31).
RS-R Super Down Sus springs for the UCF30/UFC31 LS430 give a lower drop than the Down Sus and keep a daily ride. The progressive-rate coils close up the fender gap, drop the center of gravity and tighten body roll through corners, while RS-R’s vehicle-specific rate tuning keeps the ride compliant on rough pavement.
The Super Down Sus is RS-R’s progressive-rate Down Sus spring with a lower drop. Every set is cold-wound in Osaka, Japan to a vehicle-specific rate so the car stays daily-capable at the lower ride height. Covered by RS-R’s 3-year / 50,000 km spring-fatigue warranty.
