Dexter E-Z Flex Rubber Equalizer Assembly | 7-3/4" x 2-7/8" | 9/16" Holes

High-performance rubber-core equalizer designed to absorb road shock and reduce trailer "chucking" on triple-axle configurations.

Part Number: 013-144-03 7-3/4" Center-to-Center 1-3/4" Double-Eye Springs

Overview

This Dexter E-Z Flex equalizer is a heavy-duty steel replacement solution designed for triple-axle suspension systems. Featuring an internal rubber core to dampen vibration, it provides a smoother ride and protects cargo from road fatigue. It is a direct fit for existing E-Z Flex kits and maintains your trailer's original ride height while significantly upgrading shock absorption.

R&P Service Insight

Standard steel-on-steel equalizers transfer every road bump directly to the frame. The E-Z Flex system acts as a buffer between your axles.

  • Vibration Control: Rubber core absorbs shock that would otherwise rattle your trailer and cargo.
  • Direct Fit: Designed to replace worn equalizers in K71-653, 657, and 655 kits.
  • Wet Bolt Ready: 9/16" holes are perfectly sized for greasable wet bolts to ensure longevity.

R&P Knowledge Hub: Sizing & Geometry

Compatibility: Designed for triple-axle trailers equipped with 1-3/4" wide double-eye leaf springs.

Exact Measurements: Features a 7-3/4" center-to-center distance. 3-7/8" horizontal spacing (center to side) and 2-7/8" vertical offset.

Ride Height Integrity: Engineered to match the geometry of standard equalizers, ensuring no change in axle alignment or trailer stance.

Performance Insight: The bronze-finished steel body provides superior corrosion resistance against road salt and moisture compared to raw steel units.
