Our Reviews

I took my wrangler to Diff Plus to diagnose some issues in my suspension and I kept hearing some noise when using 4×4 in the front. They quickly found the issue and sent me an estimate. One day later they had upgraded my front drive shaft with a beefy double U-joint shaft and fixed my front sway links. Not only did it fix the issue I had but now my jeep doesn’t have any noise, vibration or loose feeling. . I am very pleased with results and the fast friendly service I received.

Don’t overlook this small gem of family owned and operated business as Chris, Tara, and their team have really made this a great business for automotive needs. In addition to totally transforming the physical appearance of the business, they have added a great amount of knowledge, tools, and technology to help get vehicles properly diagnosed and back on the road at great rates.

Took our daughters car in for check engine light. They diagnosed the problem and repaired the issue in less than a few hours. They also checked the car out and made sure everything else was in good shape. I really liked that they use automation to get the estimate to you quickly with pictures and description of what the problem is. Great customer service. They will definitely be our go-to vehicle repair shop.
