Product Description

The RS-R Ti2000 Down Sus Lowering Springs (Part T550TW) are precision-engineered suspension springs designed for the Toyota Sienna with front-wheel drive from 2011 through 2020. Crafted using a titanium composite alloy (Ti2000), these springs help reduce unsprung weight while lowering the vehicle's ride height to improve stance, handling, and responsiveness. The moderate drop - approximately 25-30 mm at the front and 30-35 mm at the rear - reduces fender-to-wheel gap for a more aggressive look without sacrificing everyday ride comfort.

RS-R's Down Sus design takes into consideration factory suspension geometry, shock damping, and spring rates to deliver a balanced driving experience that enhances cornering confidence and road feel. The titanium alloy construction improves spring response and durability while maintaining compatibility with OEM shock absorbers and mount points. These springs are ideal for Sienna owners who want a refined lowered stance and improved handling characteristics for street driving and daily use.
