Product Specifications
Why This Top-End Kit Matters
The Replacement Cylinder Kit recovers lost compression, restores power, and supports reliable engine operation after wear on the TRX420's cylinder, piston, and associated gaskets. The kit components are selected to provide a robust rebuild path, helping you extend the life of your Rancher without unnecessary downtime.
For machines within the 2009–2023 range, the 86.50mm bore and included OEM-style gaskets align with factory specifications to ensure a precise, seamless fit during installation . If your model sits near the edge of compatibility (for example 2016-era variations), verify your rocker cover gasket type prior to assembly to ensure the correct gasket sealing is achieved.
OEM part numbers are provided for cross-reference purposes only. Always verify fitment using your vehicle's specific model, year, and serial number before ordering.
