Donovan Hemi 392/417 Gear Drive Assm.

*** IN STOCK SHIPS TODAY *** RBS is proud to bring the racers this Donovan 392/417 Hemi gear drive. For the racer that has always wanted to build an iron '92 or a nitro cackling Donovan 417 here is one of the main parts to make the project happen.

This gear drive starts off with a heat treated cast alum. cover that is machined to exact tolerances giving the motor it's best chance for accurate cam timing. The gear set includes a dual keyway crank gear, a idler gear that has a high speed precision ball bearing and a cam gear that uses a eleven hole vernier to dial in cam timing. The gear drive includes a mounting hardware kit, detailed installation instructions as well as a billet cam cover that you can attach a pump extension to. The cam hub uses a .375" hex shaft to drive the fuel pump.

Gear drive is set up to be used on a cast iron block, Donovan cast aluminum or billet engine blocks or any other aftermarket engine block that uses a traditional 392 gear drive pattern. All gears are made from heat treated steel and the cover uses a gasket or a thin coat of silicone for a superior seal to the engine block.

RBS can also supply pump extensions per the customers needs when ordering the gear drive at an additional cost.
