COOL YOUR LS SWAPPED C1 CORVETTE WITH A DEWITTS DIRECT FIT® AND DRIVE WORRY FREEThe first generation of Corvette, built from 1953-1962, is often referred to as the C1, but some call them “first gen” Corvettes or “solid axle” models (the Corvette would not see its famous IRS until the C2 in 1963). One thing most can agree on is that these C1 Corvette years are beautiful cars that every enthusiast dreams of owning, with much of that due to its many uses in TV shows and movies over the years. However, the ten-year production run produced barely 69,000 cars, meaning they often command a premium these days.

The C1 Corvette has a timeless design, but due to early production design requirements of using production GM components off the shelf, these early first gen Corvettes leave a lot to be desired in ride handling and performance, making them prime subjects of the “restomod” crowd. Restomodding a vehicle is when you modernize the drivetrain, suspension, and more while keeping the overall look subdued or stock appearing. To that end, the LS engine platform (which is used in the C5 and up generation Corvettes) has become an extremely popular engine upgrade. With various engine mount adapters, swap kits, and such, the LS engine is a drop in upgrade that we’re here to help keep cool with our Direct Fit® LS swap radiator packages.

BUILT TO FIT YOUR LS SWAPPED CORVETTE WITH ZERO MODIFICATIONS TO INSTALLThe LS engine family has a couple of unique traits that require a specific radiator design. While some manufacturers make do with a universal radiator that gets a “nip and tuck” to work, that’s not how we do things with DeWitts radiators. Our Pro Series Direct Fit® C1 LS swap Corvette radiator for 1955-160 models is built using the highest quality aluminum materials, assembled, furnace brazed, and TIG welded all in our Wixom, Michigan facility (just 30 mins up I-96 from GM’s corporate headquarters at the Renaissance Center). Each radiator carries a limited lifetime warranty, is pressure tested, and carefully double wall boxed with insulation to ensure it makes the trip to you and keeps your project moving forward.

Our press formed tanks provide an OE appearance and mean you won’t have any fitment issues, no matter if your C1 Corvette was originally a Blue Flame six or small block car. Flat plate welded end tanks that our competitors use rarely have this luxury, requiring modifications to your car to fit the larger tanks and/or additional bracketry or adapters. Using a two-row core built with 1-inch-wide core tubes and serpentine cooling fins (which is equivalent to a four-core copper/brass radiator) maximizes air flow contact through the core to pull away the most heat, no matter the demand on the system.

Our Direct Fit® LS swap radiator allows you to easily bolt in the best aluminum radiator for your C1 Corvette LS swap. Not only is our radiator a hassle-free install but we have properly fitted our radiator with the correctly located LS inlet and outlet radiator hose fittings, and a steam line fitting. We offer a radiator and fan package as well with all the same features and including a SPAL 16-inch cooling fan with pre-installed coolant temperature sensor to ensure your LS stays cool. Automatic transmission-equipped models feature a 4-plate internal cooler with 5/16-inch inverted flare ports. Our Black Ice two-part epoxy coating option is a semi-gloss black finish that provides an OE-like look for those that want to keep things low key under the hood.

C1 CORVETTE PRO SERIES DIRECT FIT® LS SWAP RADIATOR OPTIONSThese C1 Corvette LS swap radiators are available for 1955-1960 models. A LS swap specific model for 1961-1962 C1 Corvettes is available as well. We provide the correct DeWitts radiator configuration for a hassle-free installation. The optional SPAL 16-inch cooling fan solution, rated at 1,918 cfm, comes preinstalled, as does the fan’s temperature sensor. A complete fan wiring harness is also included when optioning the radiator and fan package. A billet 15 psi radiator cap with DeWitts logo comes with all radiators regardless of fan package or not.

For those with high horsepower LS applications or in high temperature climates that want the most cooling ability we also offer our 1955-1960 LS swap radiator and 1961-1962 LS swap radiator in our HP series with larger 1.25-inch wide core tubes for additional surface air and coolant capacity.

Our universal polished radiator overflow tanks are the perfect addition for your custom LS swap cooling system build and can be mounted almost anywhere in the engine compartment. Finally, be sure to add some DeWitts High Performance coolant to your order to protect your cooling system and help it achieve maximum thermal capabilities.
