Product Details
The Riaction GT1 Coilovers for the 2014+ Infiniti Q50 3.7 AWD deliver a premium, adjustable suspension upgrade built for drivers who want more from their Q50 3.7 AWD than the factory setup can offer. These Infiniti Q50 3.7 AWD 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 Q50 3.7 AWD to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 2014+ Infiniti Q50 3.7 AWD are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
