Traxxas TRX4 1972 K5 Blazer High Trail

The 1972 Chevrolet® K5 Blazer gets the full High Trail treatment with a big, lifted stance and beautifully detailed body. The factory-installed Long Arm Lift Kit boosts the Blazer’s ground clearance by more than an inch with larger 2.2″ wheels and tires to conquer the roughest terrain. K5 Blazer High Trail Edition delivers more of what you crave—extreme all-terrain capability, stunning scale looks, and Traxxas-Tough™ durability.

HIGH TRAIL EDITION
Large 2.2″ chrome mag wheels and Canyon Trail tires tame even the most technical trails to extend your scale adventures farther than ever before. The factory-installed Long Arm Lift Kit raises K5 Blazer over an inch taller for superior ground clearance.

DETAILED REPLICA BODY
The TRX-4 K5 Blazer faithfully reproduces one of the most iconic Chevy trucks to ever hit the trail. Bright chrome accents contrast the high-gloss paint for an unmistakable look. The injection-molded grille, side mirrors, and simulated wood trim give K5 Blazer uncompromising scale presence.

CLIPLESS BODY MOUNTING
The clipless body’s hidden latching system gives K5 Blazer High Trail Edition clean, flowing lines for new level of scale realism and convenience. On the trail, K5 Blazer’s clipless body holds tight when you need it, but releases in just seconds to access the chassis.
