Chassis and Suspension: Chassis and suspension components are molded from Team Losi's extra-rigid Stiffezell composite material to withstand the punishment of off-road racing's toughest tracks.
Tweak Resistant Construction: The unique interlocking construction and hi-tech materials used make an almost tweak-free chassis for consistent razor sharp handling.
Sealed, Single-belt Drivetrain: Delivering all the remarkable performance of 4WD, but with the maintenance simplicity of a 2WD system, the XXX-4's advanced single-belt drivetrain provides outstanding acceleration and runtime.
High efficiency Slipper Clutch: The ingenious adjustable slipper clutch absorbs impacts and protects the drive train while maintaining forward drive and acceleration on the roughest tracks.
Ball Bearings Throughout: Precision ball bearings on all the wheels and at critical rotational points in the drivetrain minimize friction for higher speeds and longer run times.
Easy-Access Differentials: The XXX-4's easy-access differentials drastically reduce maintenance time to that of most 2WD cars.
Exclusive XXX Off-Road Suspension: Hard-anodized, oil-filled shocks and Losi's Stiffezel suspension arms and shock towers give the XXX-4 superior handling on any track surface.
Specially Designed Drive Belt: At the heart of the XXX-4's drivetrain is a heavy-duty belt designed specifically to withstand the rigors of the most competitive off-road racing environment.
