OSC 2818SD Severe Duty Replacement Radiator

The OSC 2818SD is a Severe Duty replacement radiator engineered to outperform both OE and traditional aftermarket cooling solutions. Part of OSC's newly launched Severe Duty Cooling Product Line, this radiator is purpose-built for vehicles operating under demanding conditions including towing, high mileage, and extreme temperatures where a standard replacement simply isn't enough.

Key Features:

• Severe Duty Construction — Built to exceed OE specifications with upgraded materials and core design for extended service life
• Resin-Reinforced Headers — Provides enhanced leak protection and structural integrity under high-pressure, high-heat cycles
• Larger Core & Optimized Fin Density — Maximizes airflow and heat dissipation surface area for superior cooling capacity
• Corrosion-Resistant Materials — Engineered to withstand road salt, moisture, and environmental wear
• Direct-Fit Replacement — Designed to install in place of the original radiator with no modifications required
• Pre-Tested Assembly — Each unit undergoes cycle, vibration, burst, and environmental testing before leaving the factory

OSC Automotive (distributed by US Motor Works) has been a trusted name in automotive thermal management for decades, offering over 1,400 SKUs across radiators, condensers, and heater cores. The Severe Duty line addresses known OE design shortcomings, making the 2818SD an ideal upgrade for vehicles that demand more than a standard replacement radiator can deliver.
