The LIMITLESS street basher excels on all roads, in all conditions: on loose gravel, asphalt, or short grass, and in the sun, rain, or even ice. It's bash-hardened and fully customizable, allowing you to tune the aerodynamic balance just how you want it.

In addition to the low drag LIMITLESS body, which comes already trimmed and decaled, we've included front and rear wings that can be customized to tailor the downforce to your preference. To further enhance the aerodynamics, the chassis design includes a front splitter to balance downforce distribution and a rear diffuser that increases downforce and grip, enabling you to corner faster and with confidence.

DESIGNED FAST, DESIGNED TOUGH — underneath the aerodynamically engineered body is a 3mm anodized aluminum chassis with a center brace for maximum strength. The heavy-duty 4X4 drivetrain features durable steel drive shafts plus all-metal diff outdrives and gearbox internals. The diff module can be removed by taking out just four bolts, making maintenance as speedy as the LIMITLESS roller itself. A sliding mount makes motor access quick and easy, too.

Big bore oil-filled shocks on black-anodized front and rear shock towers keep the dBoots Hoons all-road tires firmly planted for maximum traction. The tires are mounted on speed wheels with extra-durable hubs.
