All aluminum radiator.  Factory radiators are fine for stock engines, but as you start to increase power, the stock radiator can soon reach its cooling limits.  Our aluminum radiators with billet filler neck are all welded with no epoxy or solder joints.  Each radiator has two rows of 1" wide cores, doubling the cooling capacity of the factory radiator.  Each radiator also has a 7 plate transmission cooler that can also be used as a power steering fluid cooler for cars with a manual transmission.  These radiators take full advantage of the available space in your vehicle and may require slight modifications to your mounting brackets and shrouds.
