Enhance stability and precision in your 2009-2021 Nissan 370Z Z34 with Riaction Traction Plus Ultra coilovers. Designed for the wider, more rigid Z34 chassis, the TPU system improves braking composure, sharpens turn-in response, and delivers more controlled rear traction during aggressive cornering and acceleration.

At the core of Traction Plus Ultra is our new digressive piston design, engineered to provide strong low-speed damping for improved roll control and steering accuracy while maintaining composure as suspension velocity increases. On the Z34 platform, this translates into more consistent weight transfer, greater high-speed stability, and improved driver confidence during spirited driving or track sessions.

Each kit features a nickel-coated shock body for superior corrosion resistance and long-term durability. The hex screw preload collar locking system ensures secure spring preload under repeated hard use. Signature orange-coated non-MacPherson components add durability and a distinctive performance finish, while pillowball upper mounts are included where applicable to maximize suspension articulation and steering feedback.

Every Traction Plus Ultra system is backed by our 2-year factory warranty.
