Good To Know

Q: Do I need any other parts to finish a top-end rebuild? A: This kit covers the cylinder, piston, gaskets, and camshaft, but you may also need valve seals, timing components, or new head bolts depending on wear. Inspect the head and timing chain before assembly.

Q: Is a service manual required for installation? A: These components involve precise torque and timing procedures, so following the factory service manual is strongly recommended. Incorrect camshaft timing can cause severe engine damage.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
