Brian Crower Polaris XP1000/XPTurbo/XP900 Dual Spring/Titanium Retainer/Seat Kit

If you're pushing your Polaris RZR's engine hard, especially at higher RPMs, you know how important it is to keep the valvetrain stable. This dual spring kit from Brian Crower is designed to handle those demands, offering improved valve control when you're really leaning on the throttle. It's a well-built upgrade for enthusiasts looking to get the most out of their engine.

This kit includes dual springs, which means you get a main spring and an auxiliary spring working together. This setup is great for controlling valve float, which can happen when the engine speed gets high enough that the valves can't close properly. The kit also comes with titanium retainers, which are significantly lighter than steel ones. This weight reduction helps reduce stress on the valve springs and the rest of the valvetrain, allowing it to operate more smoothly and reliably at higher engine speeds. The kit also includes valve seats, ensuring you have the necessary components for a complete installation.

When you're rebuilding or upgrading the top end of your Polaris engine, components like these are crucial for ensuring durability and performance. Brian Crower is known for making solid valvetrain parts, and this kit is no exception. It's a popular choice for those looking to enhance their engine's capabilities.
