Customer Service Guarantee
GEAR VENDORS makes the highest quality, most expensive overdrive you can buy. We back that with customer service and warranties you do not commonly find in business today. Call us at the factory and you will talk to real enthusiasts that know drivetrains. Our factory people will ask you the details of your vehicle and its use and then recommend our product only if it is going to be exactly what you expected and give you great benefits in your application (which is exactly why we can give a money back guarantee). These factory reps can give you the details of installation and use and send you photos, diagrams, and brochures for free. If you are installing yourself we will ship product direct to you with full factory support. If you would like to have one of GEAR VENDORS 500 nationwide dealers install the product - we will make sure to communicate with the local dealer and get your exact product in his hands for the install day. All or products come with a money back guarantee and a 2 year unlimited mileage warranty (except diesel manual truck and commercial applications see warranty for details). Last but not least — we do not show pictures of racing and then deny your warranty if you race (hard to believe so many companies do just that). All GEAR VENDORS warranties cover you on the street and at the track

Gear Vendor

GEAR VENDORS has been manufacturing overdrives for 27 years. We have been reducing fuel emissions on the most powerful and fuel consuming gas and diesel vehicles for nearly 3 decades before Green House gas emissions became the buzzword they are today. GEAR VENDORS equipped vehicles are responsible for reducing emissions nearly 25% in the average application compared to the non-equipped stock counterpart. With nearly 75,000 units in service we are reducing tons of emissions per day. Whether your purchase of our product is for a brand new diesel truck or a 1960's muscle car it is nice to know this performance product can substantially benefit the planet and our countries oil dependency.

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.
