Purchased two of these (single pass 24 inch) for 2011 Silverado 5.3 V8 and 6 speed trans used for towing a travel trailer. Over-all very solid construction and effective cooling. Very pleased with the quality. They hold quite a bit of oil so be sure to buy plenty for refill after installing. Consider direction of air flow over the fins when installing to get best efficiency.
