These work great. If you're looking for brakes for your 3500 lb axle these are most likely the correct ones.

Comes with set of pads.

Product was as expected. Packaging was a concern with box busting out and susceptibility to damages. Inspection found none. A few bolts were started cross threaded that could have damaged the threads. Operation has shown no issues and functions as expected. As stated this come with a set of pads so no need to order separate set as recommended by Amazon.
