The Industrial Injection 14mm Gorilla girdle ships with ARP XL main studs and requires a stamped oil pan for installation. This thicker .500‑inch component reinforces main caps and the crankcase interface, providing increased clamping and bottom‑end rigidity. It is intended for applications where larger 14mm studs are used and where the stamped oil pan clearance is available.
