The Truck Master Set includes an updated manual with clear instructions, photos, and diagrams for domestic and import heavy duty trucks and big-rig's. This kit includes all of the tools and accessories to make your job fast and easy. Please note: Our tools are no longer Chrome. Currently our In-The-Door tools are Stainless Steel. While not as shiny as they may have been in past years, they remain of very high quality and rust resistance for extended usability.
