Watch Insane Colorado Prerunner Build Take Shape

By -

LS7-powered Colorado Prerunner is a 730 hp off-road weapon.

There comes a time when we all become a little bored with our stock rides. Generally, that’s when you start to purchase one or two aftermarket parts at a time. Sometimes things spiral into a complete transformation. But rarely does it result in something like this – an LS7 powered Colorado Prerunner constructed from a bone stock truck.

Indeed, this insane off road weapon began life as nothing more than an unassuming, 2015 mid-size truck. Shortly after taking delivery of the shiny Colorado, the guys at Roadster Shop in Mundelein, Illinois proceeded to rip it apart. Armed with a concept drawing and a slew of aftermarket parts, they completely transformed the little truck into something absolutely amazing.

The original engine won’t cut it in the desert, so now a dry sump, 730 hp LS7 lives under the hood. Backing up that fire breathing beast? A built 4L80E transmission and 9″ Currie full floater rear end. The suspension was built in house and features a full 22″ of travel up front and 27″ in the rear. It utilizes goodies like 4130 front arms, spindles, and trailing arms, along with Fox racing shocks.

Brakes have been upgraded as well, with huge 6 pot Wilwood pistons at all four corners. A set of Ultra 103 wheels, wrapped with 37×12.5R17 BF Goodrich Baja T/A KR rubber, covers them up. Like the suspension, Roadster Shop custom fabbed the wide body in house, and it simply looks incredible. The entire build is a testament to the quality of Roadster Shop’s work. And it’s well worth 13 minutes of your life watching it transform in this DIY Garage video.
