Cool Your LS Swapped C1 Corvette with a DeWitts Direct Fit® and Drive Worry Free

The 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 Install

The 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 HP Series Direct Fit® C1 LS swap Corvette radiator for 1961-1962 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 laser cut and welded tanks on these models provide the best fitment, no matter if your C1 Corvette was originally a Blue Flame six or small block car. Competitors tanks often require modifications to your car to fit the larger tanks and/or additional bracketry or adapters. Using a two-row core built with 1.25-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. The wider core tubes of our HP series radiators provide even more cooling ability over our base Pro Series while also holding more coolant.

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. A SPAL 16-inch cooling fan with pre-installed coolant temperature sensor and full wiring harness are provided 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 HP Series Direct Fit® LS Swap Radiator Options

These C1 Corvette LS swap radiators are available for 1961-1962 models. A LS swap specific HP model for 1955-1960 C1 Corvettes is available as well. We provide the correct DeWitts radiator configuration for a hassle-free installation. A billet 15 psi radiator cap with DeWitts logo comes with each radiator.

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.
