Try our gear ratio and rollout calculator to find the right pinion and spur for your car, whether it's Team Associated, Tamiya, Traxxas, or any other make. Enter your car's internal drive ratio to see the final drive ratio (FDR), and see the percentage change in gearing you'll get from a new pinion and spur.
the gear charts designates a gear ratio that will not fit in the vehicle. Gear fitment will also depend on the motor brand.
Understanding your vehicle’s gear ratio is a powerful tool when making changes at the track or around the backyard. Whether you’re aiming for longer run times or to set a land speed record against your friends, knowing what to change and busting out some simple math makes it easy to see how gearing works.
Calculate your ratio, your final drive ratio (FDR), and rollout, and see exactly how much of a difference a gear change will make.
Use the following calculator to determine the gear ratio of your radio control vehicle. The gear ratio calculator uses 2 combinations of gears to output an overall drive ratio. The first set is the main gear set which is generally starting at the motor or nitro engine.
