Brian Crower Nissan TB48 Single Spring & Titanium Retainer Kit

The titanium retainers in this Brian Crower kit are notably lighter than stock steel ones. This reduction in mass at the valve train means less inertia, which helps the valves close more reliably at higher engine speeds. This is a well-built kit designed to handle the demands of performance-oriented Nissan TB48 engines.

Brian Crower is known for making solid valvetrain components, and this single spring kit is no exception. The springs themselves are made from a strong, durable material and are designed to work with the included titanium retainers. This combination helps prevent valve float, a condition where the valves can't keep up with the camshaft's rapid lift and closing cycles, especially when you're pushing the engine hard.

If you're rebuilding or modifying a Nissan TB48 engine for increased performance, this kit is a popular choice for improving valvetrain stability. It's a direct replacement for the stock components, making installation straightforward for someone familiar with engine work.
