In a slipper spring suspension system, the equalizer links adjacent springs and pivots on a central bolt. When one axle encounters uneven terrain, the equalizer rotates and transfers load to the adjacent axle, helping maintain tire contact and balanced suspension loading.
Greaseable center bolts allow lubrication of the pivot point which significantly increases suspension component life. Always confirm axle spacing, spring width, and pivot bolt diameter before ordering replacement equalizers.
