Rollmaster LS3/L99 SINGLE BOLT Double-Roller Adjustable Timing Set - 4X Cam Gear

This double-roller timing-chain set is a perfect complement to our high-performance camshafts and other LS3/L92 engine components. It offers greatly enhanced strength and accuracy compared with the stock piece and even allows for timing adjustments (advance or retard) of up to 8 degrees. The set contains an adjustable, nine-keyway nitrated crankshaft sprocket; a double-row chain; a nitrated camshaft sprocket; two oil-pump-spacer plates; detailed instructions; and all necessary installation hardware.  It will also include a Torrington bearing that MUST be installed behind the upper timing sprocket!

This timing set is designed with a 4X cam signal which is compatible with a 58X crank reluctor!

**NOTE** WILL NOT WORK ON FACTORY DRY-SUMP SYSTEMS!
