      Description

      These water necks fit Mopar Gen III Hemi engines, and are ideal for use in engine swaps since the swivel allows adjustment to accommodate custom radiator hoses. The billet aluminum with black anodized finish looks great and prevents corrosion. Choose from outlets with a 45 degree or 90 degree angle (both swivel 360 degrees before bolts are tightened up).
