We dedicated years of research and development to make our dual idler gear portals unlike anything you™ve ever seen before. Adding a second gear in the portal box spreads the force over twice as much surface area for better, more reliable torque transfer. But these aren™t any old dual idler gears. We use precision CNC grinding to ensure a perfect fit. We use industry-leading 9310 steel alloy for quality and durability too. They™re the strongest gear set you can get. Pick Your Gear Reduction We let you choose your gear reduction to customize your ride down to the smallest detail. A 15% gear reduction is perfect for adding strength for the occasional mud pit while preserving your rig™s top speed. If you want to add huge tires, a 30% gear reduction will help you get the power you need to keep those monsters turning. No matter how you ride, we™ve got the perfect gear reduction for your Pro R.
