Riaction Coilovers
GT-1 : Linear
The GT-1 Linear is our most popular coilover system, engineered for drivers who want reliable handling with on-the-fly tuning. Featuring a height-adjustable body and 32 levels of rebound damping, this setup lets you fine-tune ride comfort and response with ease.
Linear valving provides predictable, consistent feedback — ideal for daily driving, spirited canyon runs, and occasional track days.
GT-2 : Linear 2-way
The GT-2 Linear 2-Way Coilover Kit builds on the proven GT-1 platform, offering the same height-adjustable body and rebound control, with the added benefit of compression adjustability via external reservoirs. This dual-adjustable setup provides deeper tuning flexibility for those who demand precision on the track.
The external reservoirs also increase fluid capacity and improve thermal stability, reducing heat fade during aggressive driving. While built with motorsports in mind, the GT-2 remains street-friendly for drivers who want maximum control in all environments.
GP-1 : Digressive
The GP-1 Digressive Coilover offers superior low-speed control compared to a linear-valved system. With digressive damping, resistance increases quickly with shaft speed to a pre-set threshold — then tapers off, maintaining consistent control at higher speeds. This results in a comfortable ride during normal driving, while still effectively managing body motion during spirited driving or quick transitions.
Engineered for drivers who want refined ride quality without sacrificing performance, the GP-1 is an excellent choice for street use, canyon carving, and occasional track days.
GP-2 : Digressive 2-Way
The GP-2 Digressive 2-Way Coilover Kit takes the core characteristics of the GP-1 — including its height-adjustable body and rebound damping — and adds independent compression adjustment via external reservoirs. This dual-adjustable setup allows for deeper tuning flexibility while maintaining the comfort and control that digressive valving is known for.
The external reservoirs increase fluid volume and improve heat dissipation, ensuring more consistent performance under demanding conditions. This system provides sharper driver feedback and greater chassis stability by improving weight transfer control — ideal for those who want the most from their suspension on the street, through canyons, or on the track.
