Losi Lasernut: The Perfect Rock Crawler

Rock crawling is off-road driving at its most extreme. It uses specialized vehicles that can be as-is or heavily modified to go around obstacles. Driving heavily customized four-wheel-drive trucks, Jeeps, and "buggies" through challenging terrain is what rock crawling usually entails. Boulders, mountain foothills, rock heaps, and mountain routes are examples of places where you can drive.

A vehicle must be driven slowly, precisely, and with a lot of torque when traversing rock, which is produced by a lot of gear reductions. Rock crawlers frequently drive insurmountable barriers up, down, and across.

If you’d like a rock crawling adventure without the risk, The Losi Lasernut U4 RC is perfect for you.

The Losi Lasernut U4 is an off-road 1/10 scale buggy with four wheels that are made to handle the demands of U4RC Rock Racing.

Modeled after the excellent full-size U4 buggy created by Armada Engineering and purchased by Lasernut Racing, this buggy has three fluid-filled differentials, a fully independent long-travel suspension, aluminum shocks, a special rear sway bar, and body hinge system, and a unique rear sway bar and body hinge system.
