Pro-Line Rock-Tek Tire Weight System Overview
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.

Maximum CG Per Gram
Rock-Tek positions weight at bottom-dead-center inside the tire, delivering the greatest center-of-gravity reduction per gram added compared to traditional chassis, axle, or static wheel weights.
Reduced Rotating Mass
A bearing-supported internal design allows the mass to remain effectively non-rotational relative to the chassis, minimizing rotational inertia and reducing driveline strain compared to fully rotating brass systems.
Magnetic Bottom-Dead-Center Control
Magnetic coupling keeps the weight stabilized at bottom-dead-center during climbs and side hills for maximum stability. The kit includes mounting hardware for SCX10 III and TRX-4 front knuckles and can be easily adapted to many other crawler platforms. Rock-Tek can also be run without the magnet, allowing the weight to free-spin and self-position with gravity, while still outperforming traditional fixed brass weight setups.
Tunable Performance
With a 208g base assembly and optional addition of two 54g brass weights (PRO647902), Rock-Tek allows precise performance tuning for competition or advanced trail builds. The system can operate with magnetic coupling engaged to stabilize the weight at bottom-dead-center, or without the external magnets for free-spin operation while still maintaining most of its low-CG performance advantage. This gives drivers the flexibility to tune how the system behaves based on terrain, driving style, and setup preference.
Hidden, Scale-Correct Integration
Fully contained inside standard 1.9″ beadlock wheels, Rock-Tek preserves clean axle and knuckle aesthetics without altering track width or adding external brass clutter.
