- Spring Type: Built for 2" wide slipper spring suspension setups.
- Center Mount: Equalizer suspends from the center hanger using a 7/8" grease bolt.
- Best Practice: Verify existing equalizer length, bolt-hole diameters, retainer hardware, and hanger spacing before ordering.
R&P Knowledge Hub
Compatibility: Designed for trailer suspension systems using 2" wide slipper springs and EQ-13 style 13" equalizers.

Installation Notes: Confirm center bolt size, spring-eye bolt size, retainer hardware, equalizer length, and hanger spacing before installation.

Brand & Fitment Note
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.
R&P Repair Insight
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.
- Check the Hangers: Look for cracks, wallowed holes, or bent hanger brackets.
- Check the Springs: Confirm spring width and inspect the spring ends for wear.
- Check the Hardware: Replace worn bolts, nuts, retainers, and bushings instead of reusing damaged parts.
