What is the purpose of the three keyways on the crankshaft sprocket?

The three keyways on the crankshaft sprocket allow you to adjust the engine's timing by -4, 0, or +4 degrees. This provides flexibility for tuning your engine's performance.

What is the function of the Torrington thrust bearing or brass wear shim?

The Torrington thrust bearing or brass wear shim on the camshaft sprocket helps manage thrust loads. This ensures smooth operation and contributes to the longevity of the timing set.

What makes this a 'roller' timing chain kit?

This kit features a roller chain with .250" diameter rollers. Roller chains are generally more durable and can handle higher loads compared to silent or flat-faced chains.

About this part

Product Details

This kit gives you a fully machined steel crankshaft sprocket with three keyways, allowing you to set your timing at -4, 0, or +4 degrees. You also get a cast camshaft sprocket that comes with a Torrington thrust bearing or a brass wear shim, depending on the specific application. The roller chain itself is built with .250" diameter rollers for durability.

The steel crankshaft sprocket is machined for accuracy, giving you options to dial in your engine's timing precisely. This is especially helpful when you're building or tuning a performance Big Block Chevrolet engine and need to fine-tune valve events for optimal power delivery. The camshaft sprocket uses a Torrington bearing or a brass shim to manage thrust loads, ensuring smooth operation and longevity.

For Chevrolet applications, this kit specifically includes a brass wear shim or a captive Torrington bearing to help manage the forces within the timing set.
