  • Quality parts, pay extra for the timken!
Style: Pro-Kit
Honestly very pleased. Opened up the package when I got them to verify no missing pieces. Installed a month later and it went flawless. Time consuming but quality parts and brake in went well!!

  • Fit perfect on my Bambi Airstream and is easy to install
Don't bother replacing individual wheel bearings, brake shoes or drums. It will take way longer to do that than just install this assembly so everything is new. Remove tire. Mark 2 power wires and clip near OEM crimps. Remove axle nut but leave drum in place. Remove 4 nuts from back of brake assembly and remove. Install new plate assembly in reverse order using new crimps for wires. Grease and assemble new bearings into drum. Install drum assemblies onto axles. ... show more

  • Made in China
Style: 1-Pack
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. ... show more

  • Works fantastic
Style: 1-Pack
My stock brakes were let’s say less than adequate. I used these to add additional brakes to my trailer . I went local first spending double the money. After receiving these to my surprise they were better than what I bought from the local expert at double the cost. If you’re on the fence pull the trigger. At first you need to remember there is a break in period . I put mine on drive from south Florida to Tennessee by mile 200 I was backing down from 7 to 4 on my brake gain. I drive a 2023 gmc 2500 . When we got to the pass coming out of nc to tenn I was grateful we had the extra brakes . Trailer is a 7500 lb rated trailer 3500 lb axles . These went on and fitment was perfect. In short sadly the local guy will miss the replacement sale I’m going with these next time . ... show more

  • Great hub assembly
Style: 2-Pack
The hub, backing plate, brake, and bearing assembly arrived a day before it was scheduled and was exactly what I needed. Replaced all 4 hubs on my 2016 Forest River Grey Wolf 26DBH and they worked perfectly. That and I didn't have to mess with the brakes at all. Cut the 2 wires to the backing plate and bolt the new backing plate with the brakes already installed right on. Saved a ton of time and cuss words! ... show more

  • Wheel bolt pattern size
Style: 1-Pack
The item needs the consumer to be aware that the wheel bolt pattern must be measured correctly before ordering. Their is a steep price to return
