Traxxas TRX-4 Chevrolet K10

Experience classic square-body styling combined with the raw, unstoppable crawling performance of a specialized trail rig.

The Traxxas TRX-4 1979 Chevrolet K10 takes the legendary, award-winning platform and strips it down to its purest trail-crawling essence. Built on an extended version of the performance-focused TRX-4 Sport chassis, this rig ditches the shifting servos and unlocking differentials to shed weight and complexity. Instead, it relies on a rock-solid single-speed transmission and full-time spool-locked axles. It’s a leaner, low-CG machine engineered for unmatched reliability and low-end torque when you're picking your way through highly technical rock gardens.

Topping off this hardcore crawling chassis is an incredibly detailed, officially licensed 1979 Chevy K10 body. It features a rugged clipless mounting system that preserves its stunning scale lines—including a highly detailed two-tone grille, chrome bumpers, and side trim—while allowing for lightning-fast battery swaps. Sitting on a longer 336mm wheelbase for superior climbing stability, it uses standard 1.9-inch Canyon Trail tires for maximum grip without the elevated center of gravity found on lifted models.

Why You'll Love It

• Single-Speed Transmission: Geared specifically for low-end torque, removing the two-speed mechanism drops unnecessary weight and keeps the center of gravity low.
• Spool-Locked Axles: Full-time locked front and rear spools ensure all four wheels are clawing for traction 100% of the time, pulling you over the toughest obstacles without hesitation.
• Clipless Scale Body: Enjoy the pristine, highly detailed classic truck aesthetics without ugly body clips ruining the look, plus benefit from snap-and-go battery access.
• 13.23" Extended Wheelbase: The longer 336mm chassis footprint drastically improves steep incline stability, keeping the front tires planted when attacking vertical climbs.
