    I messaged the owner Chris off of marketplace and we started talking torque converters. I didn't know him from Adam, however it quickly became apparent he knew his stuff and is the real deal. From prepurchase through post purchase the level of customer service has been impeccable. I highly recommend checking him out. I plan to buy another converter for a street/strip application very soon.

    Took a while for me to get in because Chris had quite a few customers ahead of me. He didn’t mind me checking in and seeing when he’d be ready. Once the work was done I was happy to put a BiltRite logo on the back of my truck. 48re transmissions are known to fail, especially when a Cummins motor is turned up. Chris is all about explaining where OEM parts fail, what causes them to wear out faster, and what he’s going to do to make sure they don’t. It’s where I’ll be taking my vehicles for life.

    I have used Builtrite for years. The shop takes care of my 2009 Dodge Ram 2500 4x4 6.7l automatic truck.


    I had the transfer case shear off the back of the trans housing at 75mph. Chris came through for me dealing with the insurance company and the truck back on the road. I have a long history with my truck and Builtrite has serviced for the past 200,000 miles.


    Builtrite has been great to work with and I trust there work. You don’t think about until your down the road at speed knowing your vechicle runs solid without problems.
