Review: OEM quality. Positions clearly labeled. Self adjusting. - Work great! Uses Lucas red grease. Straight forward, but a bit messy, install. OEM replacement. One seal got smushed in shipping, even with heavy duty boxing, but supplier sent extras ASAP. Does not include wire splices/connectors. Don’t forget the break-in process, before hitting the open road. Love the self adjusting upgrade.
Review: Great quality, all mounting hardqware is included and these were a snap to install. - These were a breeze to install on my 10' Hallmark enclosed trailer. Popped off the old hubs, installed the backing plate, greased and installed the new bearings in the drums and mounted the drums on the spindle. All parts look to be of good quality and everything needed to install was included in the hardware kit, minus the wiring on the trailer. I'll add that adding the wiring to the trailer took longer than mounting these on the trailer axle.

### ⭐⭐⭐⭐⭐ Made in China
*by R***. on July 13, 2023*

So, the item is 100% as described. Fit well. And performance is well enough. I have a very heavy built 12 ft 3500lbs trailer and needed a solution to save my truck brakes. Apparently not all states require trailer brakes on smaller trailers and on top of saving my brakes I wanted to be compliant across the board. The only exception I have is everything is China. Which is fine considering we shoot ourselves in our own foot by killing these types of manufacturing jobs in the US. I dont have too many concerns with the product, however the bearings feel ultra cheap. And I feel that despite how well they are packed, I will see a failure with them sooner rather than later. Which I may just make a small upgrade to better ones sooner rather than later. And honestly, I have only put a hundred miles or so on this set up, so I still have some adjustments to make since I'd say it's safe to say the shoes are seated. But I will definitely check bearing play as well. It is nice having that piece of mind knowing what you're pulling is helping slow things down. I would recommend this product, its a great price, but I would caution about the cheap bearings and races. I think that would be a well worthwhile upgrade. Especially when you start pricing this stuff compared to the axle manufacturers. They want 200 per side just for baking plates and drums.
