Everything worked out after modifying the ebrake cable. It's worked out fantastic and wish I had done the conversion sooner!

I'm hoping to edit this review soon. Delivery was pretty good only a day later than expected. Everything seemed to fit fine although the brake lines needed to be modified. The only standing issue right now is the ebrake cable is apparently too short, so it's not ready for the road yet. I'm considering options before road test. Again, I hope to edit this soon and make it a five star across the board.

Hi Gary, thank you for your detailed feedback! We're glad the delivery was timely and that most parts fit well. We appreciate your efforts to resolve the ebrake cable issue and look forward to hearing about your road test. Feel free to update your review when you're ready. Safe driving!

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!
