FAQ
Will .020" over change compression or drivability?No meaningful change when paired with stock-style pistons and correct head gasket thickness. Expect OEM-like manners with fresh sealing.
Do these include rings?Yes, the kit is supplied with rings, pins, and clips; additional ring sets are linked above if spares are desired.
Are these right for towing builds?Yes-ideal for stock and mild performance/towing when the bores need a light cleanup and you want reliable, factory-style operation.
Do I need head studs?Head studs aren't mandatory for stock power but are smart insurance for heavy towing, tuning, or elevated cylinder pressure.
