What is the benefit of the adjustable timing on the crankshaft sprocket?

The steel crankshaft sprocket has three keyways allowing for -4, 0, or +4 degrees of timing adjustment. This lets you fine-tune your engine's valve timing for improved performance based on your specific build and driving needs.

What is the purpose of the Torrington bearing or brass wear shim?

The Torrington thrust bearing or brass wear shim is used with the camshaft sprocket to manage chain tension and reduce friction. This helps ensure smooth operation and minimizes wear on the sprocket and chain.

What makes a double roller timing chain different from a stock chain?

A double roller timing chain, like the one in this kit with .250-inch diameter rollers, is generally stronger and more durable than a stock single roller chain. This makes it better suited for performance applications where increased stress is placed on the timing components.

About this part

Product Details

This Manley Race Roller Timing Chain Kit uses a fully machined steel crankshaft sprocket that offers three different timing settings: -4, 0, or +4 degrees. This adjustability lets you fine-tune your engine's timing for optimal performance, whether you're looking for a slight advance or retard from stock. The kit includes a cast camshaft sprocket, and depending on the specific application, it either comes with a Torrington thrust bearing or a brass wear shim to manage chain tension and reduce friction.

At its heart is a durable double roller chain, built with .250-inch diameter rollers. This design is known for its strength and longevity, especially in performance applications where stock timing chains might stretch or fail prematurely. For Chevrolet Big Block applications, Manley includes either a brass wear shim or a captive Torrington bearing to ensure smooth operation and reduce wear on the camshaft sprocket. This kit is a solid option for anyone rebuilding or upgrading their Big Block Chevy's valvetrain.
