Heavy-Duty Radiators, Condensers & Charge Air Coolers

  • Engineered to meet or exceed OE manufacturer’s specifications
    For Heavy Duty vehicles that are under extreme conditions or high mileage, you need to go beyond the OE specifications to have a product that will perform and go the distance.

  • Industry-Leading Technology
    It is important to have the product of today but to also be looking forward to the new technologies of tomorrow. OSC knows the value of investing in the future.

  • Drop-in fit, form and function
    OSC understands that it is very important that each part goes in as easily as the existing one comes out and that it looks and functions like the original unit. OSC focuses on this requirement.
