2010 Coleworx Buggy - Screamin’ Blue

There are those who love it and those who hate it, but rock bouncing is undeniably one of the most exciting forms of 4-wheeling to watch. Rock bouncing rigs are purpose-built machines designed to launch up hills and rocks while holding the throttle wide open, jumping and bouncing to the top in spectacular fashion. In order to handle this full-throttle, no-fear driving style, rock bouncing rigs need to be tough. Tough in this case means components like 14-bolt axles with 40-spline axleshafts and a transfer case originally designed for a monster truck.

“Everything you need, nothing you don’t”

Bobby Tanner’s Coleworx buggy, Screamin’ Blue, is one of the original bouncers that started the bouncing revolution. Built by ColeWorx in Tennessee in 2010, it has seen more than its fair share of abuse over the years. This ColeWorx rig has competed in two seasons of the Southern Rock Racing Series, not to mention tons of hardcore wheeling.

With Bobby, rock bouncing is a family affair. His daughter Shelby and sons Ethan and Jordan are all involved in off-roading and have their own rock bouncing rigs. If you’ve ever seen a rock bouncing video on YouTube, you’ve probably seen someone from the Tanner family!

With the high horsepower and violent driving style, the tires and wheels have to be tough. The tire of choice for rock bouncing is the 43-inch Super Swamper SX sticky. These are mounted on a set of 17 inch Raceline forged double beadlocks. Generally, these rigs will run 15-20 psi in their tires to avoid “pinch flats” when running into big rocks at speed.
