Gear Drive Set for Chevrolet V8 396 402 427 454 502 Accu-Drive ED7891


Edelbrock Accu-Drive gear drive replaces stock timing 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 gears are made from billet steel with induction hardened teeth.

A unique feature of the 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 both gears.

Accu-Drive gear drives won’t stretch or wear out the way timing chains will. They also provide up to eight degrees of cam-timing adjustment in two-degree increments and have offset bushings for easy cam indexing.
