The Edelbrock Accu-Drive camshaft gear drive kit replaces a stock timing chain with a precision gear drive system.
The gear drive can be easily installed. Just replace the stock crank and camshaft sprockets with Accu-drive gears and slip in the idler assembly.
The Accu-Drive gear drive system transmits power from the crankshaft gear to a full floating main idler which drives the camshaft gear.
A unique feature of the Edelbrock Accu-Drive system is the ability of the main idler gear to float to an optimum position between the crankshaft and camshaft gears, assuring absolutely equal load sharing between the crankshaft and the camshaft gears.
The gears are made from billet SAE-1144 steel with induction hardened teeth. Gear teeth are shaved for precision operation.
The set features hardened and ground idler pins from billet steel.
Provides accurate timing with no chain stretch.
Allows multiple cam timing adjustments for optimum performance.
Compatible with all standard camshafts.
Smooth cam rotation for precise valve timing.
