Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

  • Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
  • Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
  • For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
  • Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
  • Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
  • After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
  • If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

Yes. This is a self-adjusting electric brake assembly, which automatically maintains proper brake shoe clearance during normal operation. This reduces maintenance and helps provide consistent braking performance.

Product Overview: 

Designed for tandem and multi-axle trailer suspension systems, this triangular equalizer connects compatible 1-3/4" wide double-eye leaf springs to help balance suspension movement between adjacent axles.

Its tall triangular configuration allows the equalizer to pivot as the leaf springs respond to changing road conditions, helping distribute suspension loads and accommodate axle articulation.

With a nominal 6" length and a 9/16" center mounting hole, the EQ-310 is suitable for compatible trailer suspension repairs and replacement applications. Verify the existing equalizer dimensions, mounting hole spacing, and spring configuration before ordering.
