    Stay Cool with Champion Core LS-Swap Radiators

    Champion Cooling Systems Dual-Pass Radiators are a perfect choice for your LS-engine conversion vehicle. Available for most popular LS swap applications, these radiators are constructed entirely of aluminum for exceptional weight savings over stock equipment. The dual-pass flow offers superior cooling capabilities by flowing the coolant twice across the radiator. All radiators feature a 3-row core of 5/8 in. tubing to ensure proper flow when needed most. Champion Radiators are built with 100% welded seams, brazed core technology, and absolutely no epoxy. These radiators work great for both street or race cars and support approximately 600 to 800+ horsepower cooling capacity.
