Good part, good price!
Good quality and great price! Inventory for my service truck. Shipping seems to be a gamble with any brake chamber. Never know if it'll be complete or missing all the hardware. So far it's worth the gamble because I don't return, I just replace whatever is missing.

Best Price Around
My husband works on road tractors for a living, so he is always installing brake chambers. We order them through Amazon and keep them in stock, because all the parts stores charge an arm and a leg for the same quality chamber.

Bad quality of material
I ordered 3 of this break chambers a month ago and right after the arrive. I start installing them into a trailer when I finish installing the chambers. I noticed that I needed to do something else on one of them so I start removing it and by my surprise When I was removing the knots that hold in place the chambers into the trailer the threads on the bolt get damaged really bad and since I was removing it with my impact gun it broke really easy.. bad quality on iron
