2003-2008 Nissan 350Z Z33 Traction Plus Ultra Coilovers

Enhance the balance and control of your 2003-2008 Nissan 350Z Z33 with Riaction Traction Plus Ultra coilovers. Designed for rear-wheel-drive performance platforms, the TPU system improves braking stability, sharpens front-end response, and delivers more predictable rear traction during aggressive cornering and throttle application.

Traction Plus Ultra is built around our new digressive piston design, engineered to provide strong low-speed damping for improved roll control and chassis stability while maintaining composure as suspension speed increases. On the Z33 platform, this translates into better weight transfer management, improved confidence during high-speed transitions, and more consistent grip under load.

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 during repeated hard driving. Signature orange-coated non-MacPherson components add durability and a distinctive performance finish, while pillowball upper mounts are included where applicable to maximize steering precision and suspension articulation.

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