Manley 73434 Billet Single Roller Timing Chain Set LS1 LS2 LS6 Gen III IV

The Manley 73434 is a Keyway Adjustable Billet Single Roller Timing Chain Set engineered for GM Gen III and Gen IV Small Block Chevrolet LS engines, including the LS1, LS2, and LS6. Designed for street performance and race applications, this timing set delivers precision cam timing control and long-lasting durability over factory components.

Key Features:

• Fully Machined Billet Steel Sprockets: Both the camshaft and crankshaft sprockets are CNC-machined from billet steel for maximum strength and dimensional accuracy
• Nine-Position Keyway Crankshaft Sprocket: Allows cam timing adjustments of 0°, ±2°, ±4°, ±6°, and ±8° for precise tuning
• Rolon Roller Chain: Pre-stretched, heat-treated roller chain with a heavy-duty large pin design and .250" diameter rollers for ultimate reliability and accuracy
• Induction-Hardened Billet Steel Gears: Provides exceptional wear resistance under high-load conditions
• Captive Torrington Thrust Bearing: Camshaft sprocket is machined to accept and include a captive Torrington thrust bearing for reduced friction
• No Timing Cover Modification Required: Direct-fit design installs without grinding or modifying the factory timing cover
• Single Roller Design: Ideal for street performance, mild forced induction, and naturally aspirated race builds

Important Note: This timing set is NOT recommended for applications with valve spring pressures exceeding 450 lbs. For higher spring pressure applications, consider Manley's double roller timing set.

The Manley 73434 is a proven upgrade over the factory LS timing chain, offering cam degreeing capability and improved valvetrain accuracy for any performance build on the Gen III/IV LS platform.
