About Us

Mike Nappi purchased Rocky Mountain Backroad 4x4 in 2005. He took this shop to the next level in custom fabrication, building a Ultra 4 car in 2010. Completing the 2013 King of the Hammers with that vehicle. Finishing was a big accomplishment, both for the business and Mike Nappi. Rocky Mountain Backroad 4x4 is known for its unique builds and not being afraid to try new things.

We have built many ground up race trucks, tube chassis, race cars as well as work trucks, trailers and snowcats. We also offer CNC Plasma Cutting for those custom parts you may need. Since 2005 we have been building dodge truck bumpers and custom bumpers for just about anything. Our best seller seems to be 4th generation (2010-current gas and Cummins models) Dodge 1500, 2500 and 3500 rear bumpers for $1,250. Check out the pics.
