Gear Vendors

GEAR VENDORS provides overdrive product to racing cars and trucks up to 2000hp and trucks towing heavy RV's up to 25,000lbs gcvw. Whether you are trying to move a couple tons up a steep incline or moving just a couple thousand down the track — the fastest way is with the right gearing. Add the benefits of a final overdrive ratio to reduce engine rpm and increase fuel mileage by typically 20-28% and you have a product that is the single biggest innovation you can bolt to your car or truck. With fuel costs high the overdrive can pay for itself in mileage and engine wear reductions. That makes the driving pleasure of overdrive, and performance improvements free — and then the vehicle is also worth more when/if you ever sell it with the GEAR VENDORS. In the long run it just doesn't cost you anything to own a GEAR VENDORS UNDER/OVERDRIVE™. For an in-depth discussion on which vehicles can expect these mileage gains see our "common questions" section on the web site.

Gear Vendors Under/Overdrive Torque (times) RPM (divided by 5252) = Horsepower (this can be expressed) Tq X RPM / 5252 = HP. GEAR VENDORS is one of few products that can work both sides of this equation for real performance gains as well as consistent fuel consumption reductions. Gears are multipliers of torque and our Ratio Splitting capability allows you to shift to a gear with more mechanical advantage than the next stock gear in automatic transmissions and wide ratio manuals. This also means engine rpm drops about half what it did without the GEAR VENDORS and so rpm is sustained - higher torque and rpm on shift = more HP. And then shift to an overdrive final and reduce both rpm and torque to reduce the manufacture of HP when steady cruising to improve fuel mileage and decrease wear on the engine and engine driven accessories.
