LS/LT OIL COOLERS AND OIL FILTER ADAPTERS
Earl’s Billet Side-Mount Oil Cooler Adapters are a great way to add an oil cooler to your LS or Gen V LT engines, and their slim design easily clears most headers and other external components. Right at home in any engine compartment, they’re anodized black and feature -10AN male connections and O-ring seals for years of leak-free service. Gen V LT adapters fit Corvette and truck applications only (a spacer plate that goes between the oil cooler adapter and the oil pan – part number 1127ERL – is required for truck engines).
ULTRA-PRO ONE WAY CHECK VALVES
Earl’s Ultra Pro One-Way Check Valves now feature internal stainless steel hinges and GF-600S Viton® seals, the highest quality seal material for all types of fuels, including alcohol and diesel. Based on a proven military design and more effective than conventional flapper check valves, they’re ideal for both fuel and oil systems, release to full flow at just 1 PSI, and have a high PSI Rating of 1250.
LS OIL PRESSURE GAUGE ADAPTERS
Earl’s adapter fittings are a fast, easy way to install an aftermarket oil-pressure gauge for an LS swap. Designed to screw directly into the oil passage on the rear wall of LS blocks, they’re made in the USA from 2024-T8 aluminum and compatible with almost all aftermarket sending units and mechanical gauge hoses.
LS OIL COOLER BLOCK-OFF PLATES
Earl’s GM LS Oil Cooler Block-Offs are billet-aluminum covers with an extra 1/8-NPT port that’s right on top for extra header clearance and perfect for either an oil-pressure gauge or a turbo-oil supply port. They come complete with the billet cover itself, an O-ring seal (no gasket required), and all the hardware for a fast, easy installation.
SWIVEL-SEAL BANJO HOSE ENDS
Earl’s Swivel-Seal Banjo hose ends are a welcome addition to any engine bay and are ideal for connecting -6AN hoses directly to a carburetor. Their revised design uses a stainless steel banjo bolt with copper crush washers and is available in either a stealthy black anodized finish or the traditional red/blue combination. Replacement stainless steel banjo bolts are also available separately.
Earl’s Brake Adapters are perfect for connecting -3AN or -4AN lines to 9/16-18 or 1/2-20 inverted-flare fittings on master cylinders, calipers, clutch systems, and turbo oilers. Sold in pairs, they’re compatible with most aftermarket Mopar and GM-style master cylinders and made of nickel-plated steel to handle high-pressure systems.
METRIC UNI-FLARE ADAPTERS
Earl’s Metric Uni-Flare Adapters are perfect for adapting AN lines for use with metric brake systems, clutch systems, and turbo oilers. The unique shape of the uni-flare end fits both inverted-flare and bubble-flare applications, and the increased plunge-depth length of the nickel-plated steel fittings is a perfect fit for aftermarket master cylinders and allows the use of an optional crush washer.
Earl’s Brake Tees make it easier to plumb late-model vehicles equipped with metric brake hardlines. A versatile design with M10x1.00 inverted flares on three sides, they feature a convenient 7/16-inch mounting hole compatible with countless applications.
LS DRY SUMP ADAPTERS
Earl’s LS Dry Sump Adapters optimize oil flow and make it easy to use aftermarket dry sump oil tanks with LS3/LS7/LS9 engines with dry-sump pans. Made of billet aluminum and anodized black, they feature dual -12AN O-ring female ports. Port adapters (available separately) employ an O-ring seal between the oil pan and adapter for a leak-proof seal and come with O-rings and all the necessary hardware for a hassle-free installation.
