Product Details
Tri-Axle Trailer Suspension Rebuild Kit – 3" Wet Bolts – EQ-356 Equalizers
Part Number: SRK-3A-WB-356-BB
Complete rebuild kit for a triple axle trailer suspension (commonly used up to 21,000 lb GVW applications).
Designed for standard 1-3/4" wide eye-to-eye leaf springs. Not compatible with slipper spring configurations.
This configuration includes greasable wet bolts, which significantly extend suspension service life compared to dry bolt systems. Routine greasing reduces wear on bushings, straps, and equalizers.
