Review COMPONENTSPLUS Engine Top End Kit 74.75mm 0.25mm Over Polaris Big fits XPRESS XPLORER 300 1994–2000

The Component Products Plus 54-310-11PA3 engine top end kit is specifically designed for the Polaris Xplorer 300 XP and Xplorer 300 XP Sport models with a 74.75mm bore and a 0.25mm overbore. This kit is an excellent choice for those seeking to enhance the performance of their engine or for those in need of a replacement for worn-out components.

1. Cylinder Kit: The cylinder kit consists of a new cylinder, piston, and piston ring set. The new cylinder is made from high-quality aluminum alloy, ensuring durability and better heat dissipation. The piston is engineered to provide improved compression and combustion efficiency, while the piston rings ensure a proper seal to minimize blow-by and oil consumption.

2. Crankshaft Seal: The crankshaft seal in the kit is designed to prevent oil leakage from the crankshaft. It is made of a high-quality elastomer material that provides an effective seal against oil loss.

3. Head Gasket: The head gasket in the kit ensures a proper seal between the engine block and cylinder head. Made from a high-temperature material, this gasket ensures even combustion chamber sealing and prevents coolant and oil from mixing.

4. Timing Cover Gasket: The timing cover gasket is included to seal the timing cover to the engine block effectively. This gasket helps maintain oil pressure in the timing cover and prevents oil leaks.

5. Gasket Set: The kit includes various other gaskets, such as intake and exhaust manifold gaskets, to ensure a proper seal between various engine components.

The 54-310-11PA3 engine top end kit from Component Products Plus is an easy-to-install upgrade that can provide significant benefits for your Polaris Xplorer 300 XP or Xplorer 300 XP Sport.
