Good To Know

Q: Does this kit include rings and a wrist pin? A: Yes, Wiseco piston kits typically ship with rings, wrist pin, and circlips for a complete top-end install. Verify contents against your engine requirements before ordering.

Q: Can I use this piston in a bored-over cylinder? A: No, this 48.50 mm standard piston matches the original stock bore. A bored cylinder requires an oversize piston instead.
