Product Description

The RS-R T552W is a Down Sus lowering spring set for the 2021-2026 Toyota Sienna Hybrid in both AWD and FWD configurations. RS-R engineers each Down Sus spring around the specific vehicle's OEM suspension geometry, shock dampening curve, and factory ride height -- the result is a bolt-in set that lowers the Sienna approximately 1.0" to 1.6" depending on drivetrain and axle, while retaining full compatibility with the stock shock absorbers.

The front spring rate of 3.78 kg/mm and rear rate of 4.42 kg/mm are calibrated for the Sienna's weight and suspension travel, providing a firmer but compliant spring rate that reduces body roll and improves handling response without the harshness of a race-spec compound. AWD and FWD rear drop figures differ due to the different weight distribution and axle loading of each drivetrain -- AWD drops slightly less at the rear (1.0" to 1.2") versus FWD (1.4" to 1.6"). Authentic RS-R product made in Japan. Backed by a 3-year / 36,000-mile warranty.
