Big Bore Scaler Shocks (4) for TRX-4M...








Overview


This a set of Big Bore Scaler Shocks, created particularly for the TRX-4M™. Take your TRX-4M™ to the next level of efficiency in Pro-Line Style! Much like our best-selling 1/10 variation, these miniature Big Bore Scaler Shocks function CNC machined Aluminum Shock Caps, Threaded Bodies, Bottom Caps, and Polished Steel Shock Shafts for included style and resilience over the stock shocks. A double O-ring seal on the primary shaft eliminates leaks and supplies a smooth, 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 loosen the leading cap and include silicone shock oil (20wt recommended) to fill the shock body. Replace the cap and compress the shock 3-4 times to fully lube the shock shaft. Now you're all set to begin your next small-scale adventure!


3 spring rates are included with these shocks: Green (Soft) for the front, Yellow (Medium) for the back, and optional Red springs (Hard) for much heavier bodies or just to tune to your specific conditions. It includes all hardware required to mount up to your TRX-4M™.  Do not lose out on the coolest looking and best performing mini shocks in the world, Get your own Pro-Line Big Bore Scaler Shocks today!
