Product Details
Silvers NEOMAX coilovers for the 2001-2011 Lexus SC430 RWD (UZZ40) are the flagship coilovers in the Silvers lineup, delivering premium suspension performance with simple one-way adjustability. Built for drivers who want comfort, control, and reliability, these coilovers are the ideal upgrade for both street and spirited driving.
The NEOMAX 1-Way features 24 levels of rebound/compression adjustment combined into a single easy-to-use system. This allows precise tuning of ride quality and handling response without unnecessary complexity. The mono-tube shock design with a 44mm piston ensures consistent damping, excellent heat dissipation, and resistance to shock fade during aggressive driving.
These coilovers are fully ride height adjustable through the lower mount, allowing you to lower or raise your vehicle without affecting shock travel or preload. Adjusting ride height not only gives you control over stance and appearance but also improves handling by lowering the center of gravity, reducing body roll, and sharpening cornering response.
Constructed from high-strength carbon steel with cold-bent SAE9254 springs, these performance coilovers are built for durability and stability. With lightweight aluminum top mounts, pillowball or camber plate options, and a fully rebuildable design, Silvers coilovers deliver long-term value. Backed by an industry-leading 5-year limited warranty on hard parts and 2 years on consumables, the NEOMAX series stands as one of the most trusted coilover systems available.
