VT VX VY VZ Commodore LS1 Rollmaster Performance Timing Chain Set Twin Dual Row

The Rollmaster range of timing sets are known throughout the industry for their light weight, strength, billet steel construction, and 100% CNC machined surfaces, providing reduced wear and improved accuracy.

Both the crank and camshaft sprockets are built from billet steel, and the sets have 9 keyways on the crankshaft sprocket at 2-degree increments. The relationship from crank keyway to camshaft sprocket timing is 2:1, meaning that the amount of advance or retard at the camshaft is in one-degree increments; 1, 2, 3 or 4 degrees. Multiple keyways are a solid fixture and will not move or work loose like offset dowels.

This Red series Rollmaster timing chain set comes standard with a one-piece pro-series German IWIS full roller double row timing chain.
