METAL CENTER DIFFERENTIAL
All-metal EXB gear diffs give the KRATON 4S BLX Speed Monster Truck EXtreme Bash durability. An aluminum-cased center differential has also been added that provides the ultimate traction in any surface conditions.
MODULAR CHASSIS DESIGN
Separate, easily removable chassis modules for the power system, electronics and differential components make routine maintenance fast and simple.
OIL-FILLED SHOCKS
Long, aluminum-bodied, oil-filled shocks with silicone O-rings are mounted on high shock towers. These plus wide suspension arms give the KRATON 4S BLX the plush suspension travel needed to soak up bumps.
INCREASED DIRT PROTECTION
With dirt guards for the wishbones, outdrive protectors, and taller side guards all added for extra protection against the elements, the KRATON 4S BLX is more prepared than ever for high-speed, all-road blasting.
dBOOTS COPPERHEAD 2 LP TIRES
The dBoots COPPERHEAD 2 LP tires are vented to disperse water for improved durability.
