Slightly difficult wiring hookup.

The wiring connection was a bit tight to access, but once everything was hooked up, the performance has been excellent. Brakes are strong and quiet.

Top-Notch Performance

I've been hauling a lot of heavy material for the past month, and these brakes have not let me down. They're reliable and handle the load with ease.

Well-built. Works as expected.

Installed this last week and have already put about 500 miles on the trailer. Everything is working great, no complaints.

Highly recommend.

Needed a quick replacement and this was in stock for pickup. The self-adjusting feature is a game-changer. No issues so far.

Easy Install, Great Fit

The pre-assembled unit made installation a breeze. It fit perfectly onto my Dexter axle. The 7-hole flange lined up without any issues.
