The kit includes new valve springs and retainers, which provide the necessary force to hold the valves in place at high RPMs. These springs are designed to be more durable than stock springs, reducing the likelihood of valve bounce and providing more consistent valve action.

The SBT 60-307-2 Top End Kit includes all the necessary hardware for installation, including new gaskets, bolts, and studs. The installation process is straightforward, and the kit includes detailed instructions to ensure a successful installation.

In summary, the SBT 60-307-2 Top End Kit is an excellent upgrade for those seeking improved performance and durability for their Polaris 1200 Genesis, SLX, Pro, or Virage snowmobile engine.
