GM TH350 Transmission Gear Vendors Overdrive Kit - Up To 1000HP

Suit GM TH350 / Turbo 350 with 6 Inch Long Tailhousing

A Gear Vendors overdrive unit bolts on to your existing transmission and allows for an electronic toggle to switch between final drive ratios so that you can lower your rpm at higher speeds and save your engine and your wallet. This means the GearVendors Under/Overdrive basically pays for itself! Due to the phenomenal engineering and efficiency of the GearVendors Overdrive, they can handle up to 2,000hp and the loss in wheel horsepower is less than 1 per 400hp. Gear Vendors provides overdrive products to street cars, hotrods, race cars and pickup trucks up to 2000hp and pickups 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 0.78:1 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. The easy installation also contributes to its popularity, with some simple wiring, a bolt-on installation to your transmission and a shortened driveshaft being all that's required.
