Available in hydraulic roller and flat tappet applications, COMP Cams® Thumpr™ GK-Kits add a new level of “performance sound” to your Chevy or Ford engine

After all of that hard work you’ve put into your car or truck, you expect it to be the envy of all at the local cruise-in or car show. What better way to get that than with that ground pounding sound from the pipes and that unmistakable whining from a gear drive? They’ll hear you before they see you with the new COMP Cams® Thumpr™ GK-Kit! When the time comes to prove you have the horsepower to back up the sound, rest assured your Thumpr™ Cam will deliver.

COMP Cams® Thumpr™ GK-Kits are available for any Thumpr™ Chevy or Ford application and include the Thumpr™ Cam of your choice, along with the appropriate gear drive and carefully matched lifters. Each gear drive uses precision-machined and heat-treated billet steel gears to ensure the ultimate in durability and timing accuracy. Each kit features a 3 keyway crank sprocket which allows up to 4 degree of advance or retard.
