Traxxas Complete High Stall Gear Clutch

I bought this to achieve lower gearing for my Stampede for use as a trail truck. 12t/83t is lower than 9t/54t. The quality is poor. It's a basic slipper and the spur mount is plastic and not "flat". The spur wobbles too much to get good gear mesh. If for some reason you want 48P gearing on a Traxxas 4x4, don't buy this, just get a different spur and drill it to fit the stock slipper.
