RPC Water Necks and Accessories

RPC makes it easy to replace your worn OE water neck with a full selection of both gasket and O-ring style water necks for use in GM, Ford, and Mopar cars and trucks. Chrome-Plated Steel Water Necks are designed with an O-ring or gasket seal. The O-ring improves sealing over gasket water necks. Aluminum Water Necks have various neck angles, leak-free O-ring, and chrome-plated or polished finish. All necks are machined to OE specs for a perfect fit and seal.
