Product Details

The Riaction GT1 Coilovers for the 1998-2005 Lexus GS300 deliver a premium, adjustable suspension upgrade built for drivers who want more from their GS300 than the factory setup can offer. These Lexus GS300 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 GS300 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 1998-2005 Lexus GS300 are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.

GT1 Series Technology

  • 32-level damping adjustment (1-Way)

  • SAE9254 cold-wound linear main springs
  • Multi-thickness valving shims for consistent damping
  • Polyurethane oil seals and 7.5W suspension fluid
  • Low-gas-pressure design for improved compliance
  • Fully rebuildable — built to be serviced, not replaced
