These kits are designed for the Kid Trax Brand Dodge Ram Dually, Dodge Charger, Roll Play GMC Denali, Roll Play Chevy Silverado, and Kid Trax Fire Trucks 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. This kit is also capable of 18 volts if you find you need more speed later.
2. Stage II Kit and 18v Battery Conversion - 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 24v 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 II upgrade.
3. Stage IV Kit and 24v Battery Conversion - 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.
We recommend a Brake Reduction Module with any speed upgrade unless you have hills to contend with.
Light it up! These cars look HOT with lighting added and it's not hard. Use your imagination selecting colors and placement! Go to the Lighting Kits section to see more options!
