GEN 3 Hemi VVT Lift Spring .650in 09-Up

The GEN 3 Hemi VVT Lift Spring .650in 09-Up from Brian Tooley Racing is designed for serious Hemi engine builders who require precise valve train control and reliability during high-RPM operation. This lift spring is specifically engineered for 2009 and newer generation three Hemi engines that feature variable valve timing (VVT) technology, making it suitable for street, strip, and competition applications.

With a lift specification of .650 inches, this spring is optimized to manage valve train geometry at higher lift profiles than stock, ensuring consistent valve control across the RPM range while accommodating the dynamics of the VVT system. The engineering behind these lift springs is critical for preventing valve float, especially at elevated boost levels or with aggressive cam timing, allowing for optimal combustion sealing.

Engine builders and installers working on 2009-and-newer Hemi platforms will appreciate the OEM-style fitment and compatibility with factory valve train components, which eliminates the need for costly machine work or additional modifications. This makes the GEN 3 Hemi VVT Lift Spring an excellent choice for those looking to enhance performance without compromising reliability.
