The legacy and technological leadership of Gale Banks Engineering in the diesel aftermarket is unquestioned. With its long history of breakthrough innovations (many patented!) in high performance gas and diesel engine development—including turbocharging and drive train—Banks has no rival. Time and again, Banks has proven its design, engineering and manufacturing prowess in whole vehicle development/modification, including Project Sidewinder, Banks/GMC Syclone and the big block twin-turbo Pontiac Firebird.
