Exactly What I Needed

My old hub was cracked, and this was an exact match for my 3.5K axle. The description was spot-on, and the quality is excellent. No complaints at all.

Solid Construction, Smooth Braking

Used these to upgrade an old boat trailer. The braking is noticeably smoother now. The heavy-duty feel of the iron drum is very reassuring. Worth the price.

Minor cosmetic scuff, excellent function

Received the item with a small scratch on the drum, likely from shipping, but it's only cosmetic. Performance-wise, it's perfect. Easy to install and the brakes work great.

Simple to install, great braking

Installation was a breeze. I had my old ones off and these on in about 30 minutes per side. Braking power is restored and feels much more confident now. Good product.

Well-made, but studs were a tight fit

The quality is there, no doubt. The only minor issue I had was getting the wheel onto the studs; they were very tight, but it worked out. Still a great value.
