ProLine Rock-Tek Tire Weight System

I tried running brass weights, magnets, and ball bearings inside my tires… and it completely changed how my crawler behaves on the rocks. The Pro-Line Racing Rock Tech system promises lower center of gravity and better climbing stability—but does it actually deliver in the real world?

In this video, I install it, break down how the magnetic system works, and test it back-to-back on the same lines—with and without the magnets engaged. The results weren’t exactly what I expected, especially when it came to traction vs tire flex.
