This BladeRunner Oil Cooler uses a durable brazed all-aluminum stacked-plate construction that allows for greater efficiency and lower pressure drop than a standard tube-fin design. This transmission oil cooler is designed to work in-line with your vehicle’s original equipment transmission cooler to provide lower transmission oil temperatures for rock-crawling and street hauling. The BladeRunner Oil Cooler kit makes installation simple with plug-and-play transmission line adaptors, direct-fit mounting brackets, stainless steel hardware, and leak-proof AN connections. No cutting or alteration of factory hardware is required. BladeRunner Oil Coolers feature a durable black finish with a laser-etched aFe POWER logo on the front and include black-anodized billet aluminum AN fittings for a sleek appearance.
