Brian Crower Nissan VK56DE Single Spring & Titanium Retainer Kit

Brian Crower is well-known for making high-performance engine components, and this Single Spring & Titanium Retainer Kit for the Nissan VK56DE engine is a prime example of their work. If you're rebuilding or modifying your VK56DE, especially for higher RPMs or more aggressive camshafts, this kit is designed to handle the increased demands. It's built to work with a range of Infiniti and Nissan vehicles, including popular models like the Armada, Titan, and QX56.

This kit includes single valve springs and lightweight titanium retainers. The single spring design simplifies setup compared to dual or triple springs, making it a practical choice for many builds. The titanium retainers are significantly lighter than stock steel retainers, which reduces the overall mass the valvetrain has to move. This lower mass helps prevent valve float at higher engine speeds, allowing your engine to rev more freely and safely. The springs themselves are made from strong, durable materials to ensure they hold their intended tension over time and under stress.

When installing this kit, it's important to ensure your camshafts are compatible with the spring pressures. Brian Crower designs these springs to work with a variety of aftermarket camshafts, but always check the specifications for both components to confirm they are a good match for your specific build goals. This kit is a solid option for anyone looking to improve their VK56DE engine's valvetrain reliability and performance ceiling.
