Pro-Line TRX-4M Big Bore Scaler Shocks (4)
Shocks Overview:
This a set of Big Bore Scaler Shocks, designed specifically for the TRX-4M. Take your TRX-4M to the next level of performance in Pro-Line Style! Just like Pro-Line's best-selling 1/10 version, these miniature Big Bore Scaler Shocks feature CNC machined Aluminum Shock Caps, threaded bodies, bottom caps, and polished steel shock shafts for added style and durability over the stock shocks. In addition, the double O-ring seal on the main shaft eliminates leaks and provides a smooth and low-friction shock action!
The Big Bore Shocks come pre-assembled in a set of 4 with all mounting hardware included. All you need to do is unscrew the top cap and add silicone shock oil to fill the shock body and experience the supreme damping action! Three spring rates are included with these shocks, Green (Soft) for the front, Yellow (Medium) for the rear, and optional Red springs (Hard) for heavier bodies or a tuning option. Get your own Pro-Line Big Bore Scaler shocks and elevate your TRX-4M performance and crawling abilities!
