2015+ Ford Mustang S550 6th Gen Traction Plus Ultra Coilovers

Take command of the chassis dynamics in your 2015+ Ford Mustang S550 6th Gen with Riaction Traction Plus Ultra coilovers. Designed for modern rear-wheel-drive performance platforms with independent rear suspension, the TPU system improves braking stability, reduces excessive body roll, and delivers more controlled rear traction under acceleration.

Traction Plus Ultra is engineered around our new digressive piston design, providing firm low-speed damping for stronger roll resistance and improved steering precision while maintaining composure as suspension velocity increases. On the S550 platform, this results in flatter cornering, improved mid-corner balance, and greater confidence during aggressive throttle application.

Each kit features a nickel-coated shock body for corrosion resistance and long-term durability. The hex screw preload collar locking system secures spring preload under repeated high-load driving. Signature orange-coated non-MacPherson components add protection 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.
