Replaced clutch and rear main seal. Exellent repair. Truck has never ran so smooth taking off and backing is so precise now. Not jumping anymore. Would definitely recomnend. Pricing was fair.

Excellent service. The manager is amazing, took my truck in on a Saturday, they fixed my differential and some broken bolts. I'm so thankful and I got to make my delivery 900 miles away. Highly recommend, great job!!
