Front struts actually wind up the coilover spring with steering action. This can make steering feel very heavy as the spring fights to re-center the steering.These spring seat bearings are installed between the upper perch and the spring. Needle bearings prevent the coil windup, and lighten the steering feel.

For maximum performance, use them on rear coilovers too. Coil springs rotate slightly when compressed.

Seat bearings relieve the compression windup, preventing the spring from bowing or binding. They allow spring perches to rotate easily for adjustment.

• Sold as a kit of two bearings and four thrust rings
