Specs At A Glance

Good To Know

Q: How do I choose between .020 and .040 oversize? A: Pick the oversize that matches your cylinder's measured bore after machining, since the piston must fit the finished bore.

Q: Can I install this piston kit with the engine in the frame? A: Top-end work is usually easier with the cylinder removed, and a service manual will guide the correct torque and clearance specs.

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