Pro-Line 6479-00 Rock-Tek Tires Weight System for 1.9" Crawler Wheels

Rock-Tek 1.9" Magnetic Tire Weight System for 1.9" Crawler Wheels (2)

Take your rock crawler's performance to the next level with the pro-line Rock-Tek Tire Weight System. Unlike traditional brass wheel weights that spin with the tire and increase rotating mass, the Rock-Tek system utilizes a revolutionary magnetically stabilized, bearing-supported design that keeps the weight positioned at the bottom of the tire for maximum center of gravity reduction and improved stability. 

Designed for serious trail drivers and competition crawlers, the Rock-Tek system helps improve climbing ability, side-hill stability, and overall vehicle balance while reducing driveline stress compared to conventional rotating wheel weights. The hidden internal design maintains a clean, scale appearance without adding bulky external brass components.

Compatible with most standard 1.9" beadlock crawler wheels and tires, this system is an ideal upgrade for popular platforms such as the Axial SCX10 III and Traxxas TRX-4.

Why Choose Rock-Tek?

Traditional wheel weights add rotating mass that can negatively affect acceleration, steering response, and driveline longevity. The Rock-Tek system keeps the weight effectively stationary relative to the chassis, delivering superior center-of-gravity reduction while maintaining responsive handling and improved crawling performance. Whether you're tackling technical rock sections, steep climbs, or off-camber obstacles, Rock-Tek gives your crawler the stability advantage needed to conquer tougher terrain.
