2334SD

The 2334SD radiator is a direct-fit replacement designed for Cadillac, Chevrolet and GMC Applications (see below Chart for vehicle applications). Built from premium-grade aluminum, this Severe Heavy Duty radiator is constructed to meet OEM form, fit, and function while delivering enhanced cooling performance under the most demanding conditions. Each unit is individually pressure tested and features cadmium-plated tubes inside and out to help prevent premature failure and extend product life.

Unlike many aftermarket alternatives, OSC maintains OE integrity by utilizing stainless steel plate or copper and brass concentric coolers where originally equipped, never substituting with aluminum. A precision die-cut gasket ensures a secure, leak-free seal, while all necessary hardware, fittings, clamps, and bushings are included for a complete installation.

Beyond OE. Built for Better.
The 2334SD is engineered to exceed expectations, delivering premium cooling performance without the premium price.
