2014+ Infiniti Q50 3.7 Traction Plus Ultra Coilovers

Bring sharper handling and composed chassis control to your 2014+ Infiniti Q50 3.7 with Riaction Traction Plus Ultra coilovers. Designed for rear-wheel-drive sport sedans, the TPU system improves braking stability, reduces body roll during cornering, and delivers more predictable traction under acceleration.

Traction Plus Ultra is engineered around our new digressive piston design, calibrated to provide firm low-speed damping for stronger roll resistance and improved steering clarity while maintaining compliance as suspension velocity increases. On the Q50 3.7 platform, this results in flatter cornering, improved mid-corner stability, and more consistent weight transfer during spirited driving.

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 load cycles. 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.
