Bring sharper response and controlled weight transfer to your 1989-1994 Nissan Silvia S13 with Riaction Traction Plus Ultra coilovers. Designed for lightweight rear-wheel-drive platforms, the TPU system enhances front-end grip, improves transitional stability, and delivers more predictable rear traction during aggressive cornering and throttle input.

Traction Plus Ultra is built around our new digressive piston design, engineered to provide firm low-speed damping for improved roll resistance and steering precision while maintaining compliance as suspension speed increases. On the S13 chassis, this translates into quicker response during rapid direction changes and greater confidence when driving at the limit.

Each kit features a nickel-coated shock body for corrosion resistance and long-term durability. The hex screw preload collar locking system ensures secure spring preload under repeated hard driving. Signature orange coating on non-MacPherson components adds both protection and a distinctive performance appearance, while pillowball upper mounts are included where applicable to maximize steering accuracy and suspension articulation.

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