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.

Q1 Will this brake fit my trailer?

This brake assembly fits most standard 7,000 lb trailer axles that use 12" × 2" electric brakes with a 5-bolt mounting flange. Please verify your axle rating and brake dimensions before ordering. If you're unsure, send us your axle tag or hub information and we'll help confirm compatibility.

Q2 Does it fit Dexter or Lippert axles?

Yes. It is compatible with many standard Dexter, Lippert, Rockwell American, AL-KO, and other 7,000 lb trailer axles that use a standard 12" × 2" brake assembly. Always verify your axle specifications before purchasing.

Q3 Is this a self-adjusting brake?

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:

Severe road vibrations and heavy payloads place immense shear stress on trailer double-eye leaf spring pivot points. When original shackle links suffer from corrosion or mechanical wear, they compromise the tracking of your entire leaf spring assembly.

Engineered for heavy-haul reliability, this 3-3/4" flat shackle link connects the spring eye directly to the equalizer or rear hanger with absolute precision. The exact 2-5/8" center-to-center hole spacing ensures proper load distribution and prevents leaf spring binding.

Built from solid 1/4" structural steel, this raw link won't stretch or deform under high-stress cornering loads. The unpainted raw finish is ideal for fabricators who require a clean surface for direct welding or custom protective plating, making it a reliable standard for utility, flatbed, or equipment trailers.
