Excellent product! My F-250 now stops on a dime even with 37" tires

Excellent product!
My F-250 now stops on a dime even with 37" tires. The 8-piston American-made B8-Barbarian big brake kit delivers strong, confident braking right out of the box. Superb quality and a perfect direct fit. Very glad I went with these, worth every penny. Thank you!👊🏽😉🇺🇲

Replaced old pads with new pads

Hi guys. Just got around to replacing the disk brake pads on my front & rear rotors on the 1965 Mustang. The rears took a little research to determine how to retract the piston. The fronts were easy peasy! I contacted your customer service, and the rep was very helpful.

I installed this in the gravel drivewayof my home with just me doing it. Took me a good while but that being said it was not bad. Most issues i had were the fact i was working on a 25 year old vehicle. The instructions were very detailed, parts fit perfectly and my Durango stops so much better. If you have any mechanical inclination you can do this. I am hooked and will for sure use them again. Thank you for providing this old Durango owner a new lease on stopping.

Thank you so much for taking the time to share your experience and for trusting SSBC-USA with your Durango build. Hearing that you tackled this install in your own driveway—especially on a 25-year-old vehicle—makes this review even more meaningful. We know projects like that can come with a few surprises, so we’re glad our instructions were clear and that everything fit the way it should. Most importantly, we’re thrilled to hear the stopping performance made such a difference. Enjoy the renewed confidence behind the wheel, and we truly appreciate your support. Welcome to the SSBC-USA family!
