COOL YOUR LS SWAPPED C2 CORVETTE WITH A DEWITTS DIRECT FIT® AND DRIVE WORRY FREE

The second generation of Corvette, built from 1963-1967, is often referred to as the C2, but some call them “mid-year” Corvettes or “Sting Ray” models (note spelled as two words, versus the later C3 generation’s “Stingray”). One thing most can agree on is that these C2 Corvette years are beautiful cars that every enthusiast dreams of owning, however the limited five-year production run and just over 100,000 built means they often command a premium these days.

The C2 Corvette has a timeless design, and the Sting Ray has seen a lot of interest in the “restomod” crowd as of late. 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 Pro Series Direct Fit® C2 LS swap Corvette radiator 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 end tanks provide an OE appearance and mean you won’t have any fitment issues, no matter if your C2 Corvette was originally a small block or big 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 C2 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, a steam line fitting, and a pair of SPAL 11-inch cooling fans with pre-installed coolant temperature sensor to ensure your LS stays cool. Automatic transmission-equipped models feature a 4-plate internal cooler with 3/8-inch NPT 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.

C2 CORVETTE PRO SERIES DIRECT FIT® LS SWAP RADIATOR OPTIONS

Our C2 Corvette LS swap radiator is available for all years of C2 production, including factory small block and big block applications. Depending upon installation needs (pin mount or cradle mount) we provide the correct DeWitts radiator configuration for a hassle-free installation. The included SPAL dual 11-inch cooling fan solution, rated at 2,780 cfm, comes preinstalled, as does the fan’s temperature sensor. A complete fan wiring harness is included, as well as a billet 15 psi radiator cap with DeWitts logo.

For those looking to maintain the original Harrison-style radiator dimensions we offer a stock sized Harrison aluminum radiator (with flat plate laser cut and TIG welded end tanks) with a single 16-inch electric fan combination that outputs 2,360 cfm of airflow. This particular option is available for 1963-1967 small block pin mount applications and is available in both natural and Black Ice finishes and with or without our optional 4-plate auto trans cooler.

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.
