The Accu-Drive® camshaft gear drive kit is a great replacement for a stock timing chain with a precision gear drive system. The gear drive is easy to install. Slipping in the idler assembly after replacing the stock crank and camshaft sprockets with Accu- Drive® gears is simple. The majority of Accu-Drives can be installed without modifications to the engine block, but some adaptation may be needed for the front cover and axles.
The Accu-Drive® gear drive system sends power to a full-floating main idler from the crankshaft gear; the idler in turn sends power to the camshaft gear. The Edelbrock Accu-Drive® system has the unique characteristic of the main idler gear being able to float to the best position in between the crankshaft gear and the camshaft gear, which ensures an absolute equal load distribution between the crankshaft gear and the camshaft gear. Both gears are crafted from billet SAE-1144 steel and have induction-hardened teeth. The gear teeth are then shaved for the highest level of precision. The set is designed with hardened and ground idler pins, also crafted from billet steel.
