This is a complete basic add-brakes kit for a single 3500 pound trailer axle using a 5 on 5 bolt pattern. The kit is designed for trailers that currently have no brakes and already have a welded brake mounting flange on the axle.

Fits many common 3500 pound axles from Dexter, AL-KO, AXIS, Quality, and similar manufacturers. Compatible with spring axles or torsion axles, EZ Lube or standard spindles.

Bolt Pattern Reference

This kit is for trailers with a 5 bolt, 5 inch bolt pattern.

Fitment Verification

• Axle rating: 3500 pound
• Backing plate bolt pattern: 2 7/8 inch center to center
• Axle tube outside diameter approximately 2 1/4 inches
• Brake flange welded to axle with four mounting holes

If your axle tube measures 2.75 inches, it is a larger capacity axle and requires a different kit. Smaller 1 5/8 inch axle tubes use smaller brake assemblies.
