These kits are designed for the Roll Play GMC Denali and Roll Play Chevy Silverad that have the gearbox pictured above. The modifications listed below will work with all of these vehicles so long as they started life as 12 volts and have the gearboxes shown above.
1. Stage I Kit - So your kid blew a motor and you want to spend just a little more to get a little more out of the car. The Stage I Kit is exactly that. You'll get a 10-15% speed gain with very little investment.
2. Stage III Kit, 18v Battery Conversion, Ride-On Speed Control - This combination will give you about 60% more speed and more run time, plus the durability of hardened steel first gears and is still pretty economical. To use the 18v Conversion Kit you'll need to switch your vehicle's connector to one of our Male Battery Connectors. Some folks start with just the 18v Conversion Kit, use that til the motors die, then do the Stage III upgrade. The optional Speed Control will give you a variable throttle and brake pedal system just like a real car. Plus no more wheel spin.
3. Stage IV Kit, 24v Battery Conversion, Ride-On Speed Control - Max it out! More then double the speed of your car with this combo. Make sure your child is ready for this much speed in an open car! To use the 24v Conversion Kit you'll need to switch your vehicle's connector to one of our Male Battery Connectors. The optional Speed Control will give you a variable throttle and brake pedal system just like a real car. Plus no more wheel spin.
We recommend a Brake Reduction Module with any speed upgrade unless you have hills to contend with or our Speed Control unit.
