These premium quality Arctic High Flow units are simply the best choice when its time to replace your factory or aftermarket radiator. Other Aftermarket radiators tend to fail quickly, fit poorly, and often leak immediately after installation. These radiators are manufactured to the highest quality and are reinforced in all critical areas to exceed the OEM specifications. All Radiators are double checked for damage before shipment and are packed with triple wall cardboard material to ensure no damage occurs in transit. This is the only radiator Dmaxstore will install in house.

DmaxStore Note: If you are going to pull the plugs on the cooler for aftermarket lines, Please start with the top one and replace it and then move to the bottom one. The cooler inside may move if both are pulled at the same time. We also recommend replacing your stock radiator anytime after 200k miles or when replacing the waterpump or trans coolers.
