Scale and Trail® Crawler

Lifted Off-Road Adventure

Traxxas elevates scale adventure with the lifted TRX-4® Chevrolet® K10 High Trail Edition. Thanks to its factory-installed Long Arm Lift Kit and oversize tires, the highly detailed K10 replica body stands over an inch taller than our standard TRX-4. The K10’s extended wheelbase further enhances the TRX-4’s already legendary off-road capability for even more fun on the trail. The TRX-4 High Trail Edition is the perfect vehicle for the driver who wants it all: extreme all-terrain capability, stunning scale looks, and Traxxas-Tough durability.

TRX-4 High Trail Edition K10
High Trail Edition

High Trail Edition

The factory-installed Long Arm Lift Kit raises K10 High Trail Edition over an inch taller for superior ground clearance. Large 2.2” mag wheels and Canyon Trail tires tame even the most technical trails to extend your scale adventures farther than ever before

Extended Wheelbase

Extended 336mm Wheelbase

K10’s steel frame rails extend the wheelbase out to 336mm to capture the pickup’s real-world proportions perfectly. A longer wheelbase also translates into greater climbing stability and a smoother, more stable ride over rough terrain.

Clipless Body Mounting

Clipless Body Mounting

K10’s clipless body holds tight on the trail but releases in just seconds to access the chassis. This hidden latching system adds a new level of convenience and scale realism to the TRX-4 by removing traditional body clips which can interrupt the body’s clean lines.
