The Riaction GT1 Coilovers for the 2000-2005 Mitsubishi Eclipse D53A deliver a premium, adjustable suspension upgrade built for drivers who want more from their Eclipse D53A than the factory setup can offer. These Mitsubishi Eclipse 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. Whether you track your D53A Eclipse on weekends or log daily miles, this D53A coilover kit dials in ride height and damping to match how you actually use the car.
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 Eclipse D53A to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 2000-2005 Mitsubishi Eclipse are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
