Product Description

The RS-R T183D Down SUS Lowering Springs offer a refined balance of stance, comfort, and performance for 2019-2025 Lexus ES350 models. By lowering ride height roughly 1.2-1.4 inches in front and 1.0-1.2 inches in rear, these springs lower the center of gravity, improving cornering stability and reducing body roll -- giving a more planted, responsive driving feel without sacrificing everyday comfort.

Constructed from high-tensile spring steel with a corrosion-resistant powder coating, the T183D set is engineered specifically for ES350 suspension geometry. The progressive-rate design ensures a firm but compliant ride under normal driving, while remaining capable of maintaining comfort over rough roads. Installation is straightforward -- with no major suspension modifications required -- and the included spring set covers all four corners for a complete lowering upgrade.
