As part of our commitment to ongoing product improvement, we recently made a number of changes to our popular high-performance LS1 oil pump. Unlike earlier iterations (and most competitors' units), these new pumps are ported on both the inlet and outlet sides. This helps keep oil temperatures down, increasing engine-component longevity and reducing power-robbing oil shear.

Each pump is fully disassembled at our facility, after which its individual components are inspected and cleaned in a heated, dual-frequency ultrasonic cleaner. Finally, our expert technicians pre-lube all critical assembly points with a leak-resistant moly lubricant and reassemble the pieces to GM blueprint specs. The completed pumps feature a corrosion-resistant coating and bear a unique serial number corresponding to their batch, build date, and assembly tech. No other LS1 oil pump offers this combination of features-at any price!

Notes: Strongly recommended for use with our head-and-cam packages or with any other high-performance LS1/LS6 application. An ideal complement to our Double Roller LS1 Timing Chain(#55000).

Timing Chain, 1997-03 LS1/LS6 Double-Roller

This double-roller timing-chain set is a perfect complement to our high-performance camshafts and other LS1/LS6 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. Compatible with all 1997-03 "Gen III" engines (LS1/LS6, 4.8L, 5.3L, 6.0L).
