Overview This listing includes two matching 13-139 trailer suspension equalizers for compatible tandem-axle slipper spring suspension service. Equalizers help the suspension articulate between the front and rear springs as the trailer moves over uneven roads, driveways, jobsite terrain, and loading areas. R&P Service Insight Equalizers are load-sharing suspension parts. When they wear, bend, crack, or no longer pivot correctly, the trailer can ride rough, wear tires unevenly, or place added stress on springs, hangers, and hardware. Pair Replacement: This listing includes two equalizers for matched side-to-side suspension service. Measurement Match: Stamped number alone is helpful, but dimensions and suspension layout still need to match. Hardware Check: Inspect bolts, nuts, bushings, hangers, spring eyes, and wear points during installation. R&P Knowledge Hub Compatibility: Reference data for this equalizer family identifies Dexter 013-139-03 / 01313903 style 10K GD equalizer applications with 38" axle spacing and 2.5" slipper springs. Vehicle / System Fit: Tandem-axle trailer slipper spring suspension where the original equalizer matches this style, stamped number, and measurement set. Installation Notes: Confirm axle spacing, spring width, hole sizes, hanger setup, center pivot layout, inside diameter, and suspension geometry before installation. Performance Insight: A correctly matched equalizer supports suspension articulation and helps distribute movement between the front and rear springs in a tandem-axle setup.
