    JBA Headers 1840S-4 Details

    JBA shorty headers are one of the best performance upgrades available for any application. Hot Rod magazine rated headers as one of the top 10 power parts installed on a vehicle. JBA shorty headers are significantly less restrictive than the stock manifolds on a vehicle and dramatically increase the power and efficiency of an engine. JBA's original shorty design is an innovation of the old long tube header. The new shorty designs yield high performance gains that hot rodders and enthusiasts look for. With durable stainless steel construction that can survive the abuse of racing, towing, and daily driving, these headers can take a beating. With heavy duty features and proprietary technology, like the JBA Firecone collector JBA shorty headers have the capacity to produce more power than any other shorty headers on the market. Each system includes high quality hardware and thorough instructions for a professional no-leak installation.
