This listing is for one R&P Carriages EQ-13 equalizer rebuild kit containing two 13" slipper spring equalizers with matching bolts, nuts, retainer hardware, and nylon bushings. These equalizers connect 2" wide slipper leaf springs on tandem- or triple-axle trailers, allowing controlled suspension movement between axles to help distribute load and absorb road shock.
Equalizers are wear-point suspension parts. Replacing the equalizers and related hardware together helps restore proper movement through the suspension system.
Compatibility: Designed for trailer suspension systems using 2" wide slipper springs and EQ-13 style 13" equalizers.
Trailer Suspension Fit: Commonly used on tandem- and triple-axle slipper spring trailers.
Installation Notes: Confirm center bolt size, spring-eye bolt size, retainer hardware, equalizer length, and hanger spacing before installation.
Performance Insight: A properly matched equalizer allows the suspension to articulate between axles, helping reduce harsh impact transfer through the trailer frame.
Selling Brand: R&P Carriages bundled trailer suspension kit.
Application Reference: 13" equalizer rebuild kit for 2" wide slipper spring suspension systems.
What This Includes: Two equalizers, grease bolts, lock nuts, equalizer bolts, spring retainer bolts, retainer nuts, and nylon bushings.
Before Ordering: Match your existing equalizer length, spring width, center bolt size, side bolt size, and retainer hardware to the measurements shown below.
Worn equalizers, elongated bolt holes, seized bolts, missing retainer hardware, and deteriorated bushings can create sloppy suspension movement, uneven axle loading, and extra stress through the trailer frame. Inspect both sides of the suspension before replacing individual parts.
