Carbon Offroad Progressive Rate Coilover Coil Springs

Carbon Offroad’s professionally engineered progressive rate coil springs are designed in Australia to improve ride quality over factory springs on your 4x4. Built to handle additional accessory loads, they maintain a comfortable and controlled driving experience both on and off-road.

These springs are specifically designed to work with the Carbon MT2.0 strut range, delivering improved handling, increased suspension travel, and enhanced articulation.

Why Choose Carbon Coil Springs?

Carbon’s goal was to create a suspension system that offers on-road comfort while supporting additional load capacity and improving vehicle handling. Off-road, the progressive rate design enhances performance and articulation across rough terrain.

Driving comfort never felt so good.

Manufactured using specially formulated spring steel, these coils resist fatigue and sagging over time. A durable powder-coated finish provides long-lasting protection against harsh conditions.

The progressive rate design allows the springs to absorb large impacts efficiently, reducing force transfer to the chassis while maintaining smooth and consistent flex under load.

Upgrade your 4WD with Carbon Progressive Rate Coil Springs for superior ride quality and performance.
