Replace your timing chain with a Speedway Tru-Gear gear drive. Unlike timing chains, a gear drive doesn't stretch, so your cam timing stays more accurate. We builds these drives with dual idler gears, making them more stable than single idler gear drives. A Tru Gear gear drive is as easy to install as a timing chain and will fit under your stock timing chain cover.
