Smooth, Even Engagement

No grabbing, no noise—just smooth, progressive braking. The tested magnet makes a difference. You can feel the quality when it activates.

Bought 6 for My Fleet – Huge Savings

Ordered with the 20% discount—saved over $90. All six installed cleanly on Lippert axles. Consistent performance across all trailers.

Conant Bradd
Reliable and Consistently Built

I’ve now installed four of these. Every one tested strong and adjusted easily. The corrosion-resistant coating is a big upgrade over older models.

Slight Drag After Adjustment

Adjusted the star wheel per spec, but had minor drag at first. Took 10–15 miles to seat properly. Now operates smoothly. Still a great unit.

Solid Braking with No Fuss

Using it on a flatbed hauler. Manual adjust works flawlessly—just pop the plug and tweak. No electrical gremlins or dragging. Exactly what I needed.
