Matt of Rochester, Minnesota, installed a Six-Gun Bundle on an ’01-04 Duramax LB7 with a 6.6L turbo-diesel
I had been dreaming about owning a Duramax and putting a Six-Gun on it for over two years and I finally got my hands on one. After having the truck for a month and a half I ordered my Six-Gun Bundle. The install was very easy; it took about 5 1/2 hours start to finish. The test drive was scary. Set it to level six and let her eat. The truck fish tailed to 50mph and when it shifted at 60mph it broke loose again and burned both back tires on the highway. Banks Six-Gun Bundle, $2000. New set of back tires, $400. Being able to burn rubber at 60mph and letting off to feel your guts unwrap from your spine, Priceless.
I live in a city of 90000+ and lots of diesel trucks and I have only seen one truck with Banks and I think he was just passing through. Everybody and their brother who has a diesel runs an Edge and none of them have even heard of Banks. The only thing those Edge guys will hear of me is the Monster as I blow past them. Thank you to Banks Engineering for giving me a product that exceeded my wildest dreams.
