What is the main advantage of these XD-A pushrods?

The main advantage is their adjustable design, allowing you to set valve lash or rocker arm pre-load in precise .004" increments. They also offer a significant increase in bending stiffness for improved valvetrain stability.

Do these pushrods come with the necessary shims for adjustment?

This specific set, the 896808-16, is listed as 'w/o Shims' meaning it does not include the adjustment shims. A shim kit is available separately if you require finer tuning capabilities.

What type of rocker arms are these pushrods designed to be used with?

These XD-A pushrods are specifically designed to be used with non-adjustable style rocker arms. Their adjustable nature allows you to set the correct pre-load or lash when using these types of rockers.

Product Details

If you're working on an LS engine that needs precise valve lash or rocker arm pre-load adjustment, these COMP Cams XD-A pushrods are a smart choice. They fit a wide range of GM vehicles, including models like the Chevrolet Camaro, Cadillac CTS, and Chevrolet Silverado. These pushrods are designed to work with non-adjustable rocker arms, offering a unique way to dial in your engine's valvetrain settings accurately.

What sets these apart is their patent-pending design, which features a smaller inner section that slides into a larger outer section. This allows for length adjustments in very fine .004" increments, perfect for getting that exact pre-load or lash. They also boast a 90% increase in bending stiffness compared to standard pushrods, which helps maintain valvetrain stability, especially when paired with lightweight rocker arms. The adjustment range covers 7.950" to 8.182", making them versatile for many LS applications.

This set includes 16 pushrods, enough for a complete V8 engine. While they come without shims, a shim kit is available separately if you need even finer tuning. These are a well-built option for anyone looking to fine-tune their LS engine's valvetrain for optimal performance and reliability.
