There's no doubting the big rig sound a set of stacks produce, and Grand Rock has been building both big rig, as well as pickup, stack kits for years. We've put together these kits that will include all of the correct hardware to mount a single stack to your existing 4" or 5" exhaust system. Don't worry if you're running a factory 3" or 3.5" system, as you can hook up to these systems, you'll just need to purchase the kit designed for a 4" exhaust, and then purchase an appropriate exhaust adapter. You can select from any of the five available stack styles, as shown below, as well as choose what diameter stack you're after. Some stacks (Aussie and Bullhorn) are not available in 4", but all other styles will be available in sizes 4", 5", 6", and 7" diameters.
Kits designed for 4" stacks will include a 4" bed kit (T-Pipe), while all other sizes will include a 5" bed kit. Each of the 5" bed kits are even specific as to whether they will mount to a 5", 6", or 7" stack due to their varying clamp sizes to mount the stack to the inside bed rail. This kind of attention to detail is what separates Grand Rock apart from the rest.
All you need to do is determine what size and style of stack you're after, and tell us what size exhaust you'll be hooking it to, and we'll make sure you get all of the parts to mount it up. Kit includes complete bed kit, single stack, and all of the mounting hardware.
IMPORTANT NOTE: Some applications may not allow fitment of stacks due to emissions components in the exhaust. You must determine that you have adequate space to install this system that will not interfere with your current exhaust configuration. If you have any questions, please contact us.
