Understanding what adds and subtracts Performance from a vehicle is what truly inspired this product!

At the heart of well-balanced performance is correct gearing. With the limited amount of significant performance-producing products out there, gears and Nitrous Oxide Systems are the two friendliest bolt-ons and, believed to be the best "bang for the buck" and "time spent on installation".

Roadrage Gears are specifically designed for Chrysler, Dodge and Plymouth FRT Drive cars equipped with what was    originally called the 604 Automatic Overdrive and renamed 41TE....and possibly something else since. They are found in a multitude of cars...PT Cruiser, Stealth, Neon, Avenger, Mini Vans etc.

These gears can be changed out in 20-30 minutes with practice, however, it is advised to spend more time on the first installation to familiarize yourself with the procedures paying close attention to the few, but important, details involved.

The customer can install these gears for the race track and remove them for normal operation. The bi-product of using the gears is that they will NOT affect gas mileage in town but will on the highway. MPH reading will most often read in the area     of 10 mph fast and these gears do ad a touch of gear-drive noise.

Instructions and website photos are for your reference only....Alternative Installations?? Have a transmission shop install the gears or recruit an experienced transmission mechanic to help.

Roadrage Gears wants everyone to be safe and have fun! The gap of few good bolt-on performance parts are limited and gears help to "bridge the gap". Your final ratio can be easily checked but most commonly range from 4.40 - 4.70 to 1 final.
