WHY GEAR VENDORS?
Drag Week™ is a battle of attrition. Not only do competitors need to run quick and consistent times throughout the week, they need to drive their cars from track to track along a predetermined route unaided by chase or support vehicles. Obviously, race engines generally don’t make good street engines, and the majority of the failures on Drag Week™ occur on the drive between the tracks.
The high compression ratios, big-lift cams, and high valve spring pressures that are essential for a high-horsepower race engine are the antithesis of an engine that needs to idle at traffic lights. Valvetrain failures are one of the most common breakdowns on Drag Week™. One way to remedy this is to slow the valvetrain down by means of lower-ratio rocker arms.
Another way is to slow the engine down completely with an overdrive transmission. Running down the highway at 2,000 rpm is much easier on the valvetrain than at 3,500 or more without overdrive. However, there are no factory transmissions that will stand up to the abuse of the 3,000+ lb-ft of torque some of the fast-class cars are making, and that’s why a Gear Vendors Overdrive becomes crucial. With it, you can reduce the direct-drive high gear of your two- or three-speed race transmission by nearly 25 percent. Gear Vendors has been a long-running sponsor for Drag Week™, and the effectiveness of its product is reflected in the number of top competitors using it. We thank Dodge, Gear Vendors, Rockett Brand Racing Fuel, and all our sponsors for their continued support of Drag Week™.
