Product Details
The Riaction GT1 Coilovers for the 2007-2019 Lexus LS460 deliver a premium, adjustable suspension upgrade built for drivers who want more from their LS460 than the factory setup can offer. These Lexus LS460 coilovers are engineered to pair street comfort with canyon and track capability, giving you the stance, handling, and adjustability you've been chasing without compromising daily driveability.
Every GT1 set features a monotube damper with 32 levels of damping adjustment, so you can tune ride quality to match the road, the weather, or your driving mood. Full-length ride-height adjustment separates preload from ride height — meaning you can drop the LS460 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 2007-2019 Lexus LS460 are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
