2017+ Kia Stinger Traction Plus Ultra Coilovers

Engineered for the Kia Stinger, the Riaction Traction Plus Ultra (TPU) Coilover System is designed to maximize stability, traction, and control on a heavier, performance-oriented chassis. This system improves rear-end response, enhances braking composure, and delivers more consistent traction during aggressive cornering and acceleration.

At the core of the TPU system is a digressive piston design, providing strong low-speed damping for sharper turn-in and improved roll control, while maintaining composure as suspension velocity increases. This results in more predictable weight transfer, greater high-speed stability, and increased driver confidence during spirited driving and track use.

Built for drivers who demand precision and durability, the TPU system incorporates reinforced components and advanced materials to handle repeated high-load conditions without compromise.
