Product Details
Tandem Axle Suspension Rebuild Kit — R83 Equalizers + Wet Bolts + Bronze Bushings (3.125" Strap)
Part Number: SRK-TA-WB-BB-R83-3125
This complete tandem-axle suspension rebuild kit is built around the EQ-R83 straight equalizer, a proven 8" double-eye equalizer used on thousands of medium-duty utility, cargo, equipment, and landscape trailers. The kit includes wet bolts, bronze bushings, 3.125" heavy-duty shackle straps, flange nuts, and hardware to refresh both equalizers and all leaf-spring eye connections. Designed for trailers with 1.75" double-eye leaf springs and standard 9/16" suspension hardware.
The R83 equalizer features a 3/4" center bolt hole and 9/16" side bolt holes, making it compatible with common Dexter, Lippert, and Rockwell hanger layouts. This kit is ideal when shackles are worn, bushings are elongated, or the suspension has excessive play.

This kit replaces all wearable connection points between your equalizers, leaf springs, and frame hangers. If your trailer exhibits uneven tire wear, noisy suspension, excessive play, or visible wear on shackles and bushings, this rebuild kit restores correct suspension geometry and reduces metal-on-metal wear.
Professional installation is recommended. Always torque suspension hardware to manufacturer specifications and verify hanger spacing during reassembly.
