Designed to sit between the spring and spring seat at one or both ends for off the shelf springs with coil ID of 2.25/2.5 Inches or 60mm

Reduces shock shaft distortion caused by each end of the spring twisting & moving into compression unevenly compressing against the spring seats.

The bearings allow the spring to move unhindered & allows ride height adjustment to be performed easier if the spring is preloaded at full droop/extension

Purchased as a set. Each set has one thrust/needle roller bearing and two flat thrust washers.

Requires occasional maintenance if not fitted into an enclosed spring seat.
