New Pro-Line Racing Rock-Tek Tire Weight System

Press Release From Pro-Line Racing:

Rock crawling has always been a fight against physics. The lower your center of gravity the more stable your rig stays. For years the approach was the same: add brass and accept the trade-offs. Static wheel weights spin at full RPM, piling on rotating mass, stressing the driveline, and dulling throttle response. Chassis weights sit too high to make a real difference, and knuckle weights add bulk without delivering the lowest possible CG. The industry has been stacking weight and hoping for the best.

Rock-Tek changes that completely.

Rock-Tek is the first magnetically locked, bearing-supported tire weight system that keeps mass planted at bottom-dead-center while the tire rotates around it. This keeps the weight effectively stationary relative to the chassis, maximizing CG reduction without the rotating mass penalty of traditional wheel weights. Instead of spinning dead mass, Rock-Tek controls weight dynamics to improve climbing stability and balance.

Rock-Tek is designed for standard 1.9" crawler tires with a 4.75"-4.9" outer diameter and integrates cleanly into serious crawler builds without adding external bulk or compromising scale appearance. The system is engineered to work with most standard 1.9" beadlock wheels and is fully compatible with Pro-Line 1.9" beadlock wheels and crawler tires. For best results and to confirm wheel clearance, users should reference the Rock-Tek engineering drawings and fitment guidelines prior to installation.

If you are serious about climbing performance, side-hill stability, and smarter weight tuning, Rock-Tek is the upgrade your crawler has been waiting for. This is not another brass ring. It is the most advanced crawler weight system ever developed.
