Reference Information

Water Neck, LS Water Pump Adapter, Straight Up, Billet Aluminum, Clear Anodized, Chevy, Small Block LS, Kit

Earl's leads the way for LS engines! OE water pumps come with push-on barbs for clamping the standard radiator hoses. Push-on hose connections just don't meet the demands of extreme performance. Earl's LS water pump adapter kits convert both the inlet and outlet to -20 AN fittings. The kits work with all LS water pumps; an O-ring adapter plate is included that upgrades early LS water pumps to the later, less restrictive style of thermostat.

Features include:
• Billet aluminum and stainless steel components
• Anodized protection on aluminum components
• Requires thermostat upgrade on early LS water pumps
• Welding required
