Meet "Shorty":
A Showcase of What We Can Do

One of our most talked-about builds is a 2005 Dodge Ram 2500 we lovingly nicknamed “Shorty.” When it first rolled into our shop, it was barely running, fresh off airport duty and ready for the scrap yard. But we saw its potential.

Unlock Your Vehicle's Potential – Custom Performance Upgrades at Wind River Auto & Diesel.

Over three months, our team completely rebuilt Shorty from the ground up. We converted it into a short bed, overhauled the engine, lowered the suspension eight inches, repainted the frame, added custom wheels, and wrapped the body in a one-of-a-kind design.

Shorty took Best in Show at the Desert Diesel Nationals in Phoenix, AZ. This was a huge honor that showcases just how far we can take a diesel performance build. It’s a fully functional, streetable truck with dealership-level refinement—built in our own Riverton shop, by our own hands.
