OSC 2791SD Severe Duty Replacement Radiator

The OSC 2791SD is a Severe Duty replacement radiator engineered to outperform both OE and traditional aftermarket cooling solutions. Part of OSC's new Severe Duty radiator line, the 2791SD is purpose-built for vehicles subjected to extreme operating conditions, high mileage, towing, or other demanding applications where standard radiators fall short.

Key Features:

• Severe Duty Construction: Built with premium-grade Alcoa aluminum and heavy-duty components designed to exceed OE specifications and deliver superior longevity
• Cadmium-Plated Tubes: Tubes are cadmium plated inside and out to prevent premature failure and resist corrosion
• Individual Pressure Testing: Each unit is individually pressure tested before and after assembly using state-of-the-art cycle, vibration, burst, and environment testing protocols
• OE Design Improvements: OSC identifies and corrects known OE design failures, resulting in radiators with better life expectancies than the originals
• Drop-In Fit: Engineered for multi-fit installation — goes in as easily as the existing unit comes out with no modifications required
• Die-Cut Gasket: Includes a precision die-cut gasket to ensure a leak-free seal
• All Necessary Hardware Included: Comes complete with all required fittings and hardware for straightforward installation
• OES Cooler Design: Meets OES cooler specifications with stainless steel or copper concentric coolers where originally equipped — no aluminum substitutions
