Extended Billet Lifters Pair for Dyno Flathead Engines

Push the boundaries of your flathead's potential using the Extended Billet Lifters pair from Dyno. These precision-crafted components extend lash adjustments, allowing for advanced cam profiles that unlock deeper power bands in kart applications.

Unmatched advantages:

• Billet aluminum construction for lightweight strength and thermal stability
• Extended length optimizes rocker geometry for higher lift without binding
• Hardened surfaces minimize wear on cams and pushrods
• Sold as a matched pair for symmetric performance

The DEL (SKU: DEL) simplifies valvetrain tuning, keeping your engine compartment neat and adjustable on-site. Racers harnessing these lifters experience sharper valve events, translating to explosive acceleration from low speeds—ideal for technical circuits. This upgrade not only boosts horsepower but also extends component life, reducing the frequency of teardowns and enhancing overall race readiness. Integrate them into your build for a setup that responds instantly to your inputs, giving you the tools to outpace rivals consistently.

Feel the precision in every shift as these lifters elevate your flathead from stock to dominant.

Frequently Asked Questions

Q: Why should I upgrade to extended billet lifters for my flathead engine?

A: Extended billet lifters allow for the use of more aggressive cam profiles by providing the necessary length to maintain proper rocker geometry. This helps unlock higher lift potential and improves valve train stability, which is essential for competitive kart racing.

Q: Are these lifters compatible with stock valve springs?

A: While these lifters are designed for performance builds, they are typically used in conjunction with upgraded valve springs to prevent valve float at higher RPMs. Ensure your valve spring pressure is matched to your specific cam profile and lifter setup.

Q: Do I need to perform any special break-in procedures for these lifters?

A: Yes. Because these lifters feature hardened surfaces, it is critical to use a high-quality break-in oil with zinc additives (ZDDP) during the initial run-in period to ensure the lifter face and cam lobe properly mate and prevent premature wear.

Q: Can I use these lifters on a stock engine build?

A: These are designed for performance-oriented flathead engines. While they can physically fit, they are optimized for engines running advanced cam profiles where the extra length is required to correct rocker arm geometry.
