Zip valve sleeve

Hardcoat anodized aluminum valves and highly wear-resistant, billet aluminum sleeves provide extra protection against future wear.

Putting a steel valve in an aluminum bore invites leakage at operating temperature because the metals expand at different rates. Zip Valves avoid this by only using steel when the OE design calls for it.
