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.
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 336mm Wheelbase
K10’s steel frame rails extend the wheelbase out to 336 mm 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
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.

Molded Scale Details
K10 High Trail Edition features beautiful precision-molded details for a whole new level of scale realism. The authentic chrome wheels, side mirrors, and windshield wipers provide the perfect scale touches.
Factory-Installed Long Arm Lift Kit
The Traxxas Long Arm Lift Kit includes extended GTS aluminum shocks, longer links and rod ends, extended driveshafts and T-Lock cables, and a new servo mount. The lift kit works as one coherent system not only to raise the truck, but also to maintain TRX-4’s carefully tuned suspension geometry.
Clipless Convenience
K10’s heavy-duty clipless body mounts integrate into its rugged inner fenders to form a vice-like grip. When it’s time to release the body, simply reach under the fender and pull the tabs. It’s that easy.
Heavy-Duty Frame Rails
A thick 1.5 mm steel ladder frame with molded cross members provides exceptional torsional rigidity to resist even the worst chassis twisting articulation. This extremely rigid backbone lets the suspension do the work it was designed to do. You’ll feel the difference on trails where the elimination of chassis flex allows for precise wheel placement when navigating technical terrain.
Chrome-Finish Differential Covers
Classic style meets modern technology underneath the K10 pickup with realistic mirror chrome differential covers. These polished details take the scale look of the front and rear portal axles to the next level.
Raised Center Driveshafts and Suspension Links
TRX-4’s radical portal axle design raises the driveshafts higher to improve axle geometry and reduce driveshaft angles. Higher driveshafts and suspension links pass over obstacles to avoid high-centering your truck and reduce overall grinding wear.
High/Low Transmission
Why carry your crawler down the trail when you can drive? K10 features a high speed gear to get you to your next crawling challenge quickly. When you get there, flip the rocker switch on your transmitter to engage low range and conquer tough terrain with exceptional torque.
Molded Inner Fenders and Floor Pans
Tough inner fenders mount directly to the frame and shock towers to provide substantial look and feel to K10. Molded floor pans integrate into the fenders to keep rocks, mud, and twigs out of the chassis.
Titan 21T 550 Motor
Torque rules the trail! TRX-4’s massive Titan 21T motor pumps out huge torque to get you up and over anything that gets in the way. An integrated cooling fan keeps temperatures down for extended run times.
2.2″ Canyon Trail Tires
K10 High Trail Edition rides on oversize Canyon Trail tires for additional ground clearance and rock-crawling performance. The ultra-soft S1-compound rubber and aggressive lug pattern delivers unmatched grip and rugged climbing action.
Extended-Length 110 mm GTS Shocks
K10’s extra-long 110 mm GTS coil-over shocks are oil-filled to smooth out even the roughest trails. These silver-anodized aluminum shocks deliver silky-smooth damping and feature threaded bodies for easy ride height adjustment. The convincing scale realism looks great and they perform even better with an O-ring cap seal and dual X-ring shaft seals.
Torque Twist Eliminated
On conventional rigs with the limited gear reduction in the differentials, motor torque is applied to the frame to the point of twisting you right off the rocks. TRX-4’s portal axle design reduces the gear ratio at the wheels, virtually eliminating torque twist through the chassis.
T-Lock™ Remote Locking Differentials
Traxxas gives you complete control over the front and rear differentials to suit your driving needs. Leave the differentials unlocked for relaxed driving on the trail. When the trail gets technical, lock the front and rear differentials, or just the front differential, for superior pull and grip over extreme terrain. Sleeved micro cables control the differential action for scale appearance, without limiting the huge suspension articulation.
Waterproof Metal Gear Servo
A full-metal gear digital servo gives you the durability and steering authority you need to confidently and reliably power through tough challenges.
