Self-Adjusting Works Like a Charm

No more manual star-wheel tweaks. Brakes stay tight and responsive even after weeks of heavy hauling. Huge time saver.

Works Perfectly but Mounting Bolts Not Included

Note to buyers: you’ll need to source 7-flange bolts separately. Other than that, fit and finish are excellent—spun freely on install.

Easy Install for DIYers

Even if you’re not a pro, the two-wire hookup is simple. Took me under 45 minutes per side. Brakes adjusted themselves within two uses.

Excellent Value at 20% Off

Bought six for a full axle upgrade. Quality is consistent across all units. The corrosion-resistant coating is a nice touch for wet climates.

Strong, Reliable Braking on My 10K Trailer

Installed on a tandem axle flatbed. The self-adjust feature works perfectly—no dragging or uneven wear after hundreds of miles.
