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:

Complementing the heavy-duty size and capacity of 3" x 3" trailer hitches, the CURT Industrial Duty ball mount is a dependable extension of your truck. Its 3" x 3" shank is built with an I-beam shape, giving it greater strength for maximum towing capacity. It is constructed from solid, forged steel, making it even stronger for the toughest of towing jobs.

To make sure this heavy-duty ball mount can keep up with the hardest-working trucks, it is fully tested at the Detroit engineering facility. This allows the rating of this heavy-duty ball mount to 21,000 lbs. GTW and 2,800 lbs. TW.

CURT Industrial Duty ball mounts are also built to outlast the elements, featuring a highly durable carbide black powder coat finish, protecting the ball mount against rust, scratches and chipping. This particular ball mount also comes with a 1-1/4" trailer ball hole and a 2" rise and 4" drop to accommodate larger pickup trucks, helping the trailer to ride level with the road.
