Cloyes 9-3659X3 True Roller Timing Set - SBC LS1

This performance camshaft and sprocket kit offers infinite valve timing adjustability of up to +/- 6 degrees, allowing for maximum engine performance tuning. The one-piece camshaft sprocket design features a billet eccentric camshaft dowel bushing, ensuring precise and durable operation.

Both the billet steel sprockets are heat-treated for enhanced durability. The kit includes a TRUE Roller 0.250" Roller Diameter "Z" Chain, which is designed to reduce friction compared to standard high-performance chains. The "Z" Chain is approximately 33% stronger overall than the standard high-performance chain, thanks to its press-fit center link design that increases load distribution.

The links of the "Z" Chain are heat-treated and processed to maximize ultimate breaking strength while maintaining ductility for toughness. The chain is also pre-stressed to increase its fatigue life. Additionally, the kit includes a captured needle camshaft sprocket thrust bearing, which helps minimize block thrust surface friction.

The 3-piece sets are hand-matched to ensure the correct center distance and minimize runout, providing a precise and reliable installation. This performance camshaft and sprocket kit carries the part number 9-3659X3 and is designed for a specific vehicle application.

The package weight for this kit is 1.898 kilograms, and it serves as a direct replacement for the OEM part number 9-3659X3.

In summary, this high-performance camshaft and sprocket kit offers the following features:

• Infinite valve timing adjustability of +/- 6 degrees for maximum engine tuning
