Product Details

Features

  • Ball-milled polished aluminum timing tab for a distinctive, machined look

Description

Get precise, easy-to-read timing mark alignment with this ball-milled polished aluminum timing tab, sized for 6"–7" diameter harmonic balancers on Chevy Small Block and GM 90° V6 applications. The ball-milled style gives it a distinctive, machined look, while the adjustable design lets you fine-tune pointer position for accurate timing checks. Mounting hardware is included.

Important: this tab is not compatible with 4.3L V6 engines equipped with a balance shaft — verify your engine's configuration before ordering. Confirm your harmonic balancer diameter falls within the 6"–7" range, since timing pointers are balancer-diameter specific.
