On-Board Air Systems & Accessories

For over a decade, Kilby Enterprises has been the leader in On-Board Air systems. Our Airboss systems provide enough air to run air tools with ease without over taxing the system. Don't be fooled by other manufacturers' claims! We use only top of the line components that meet our rigorous standards, including the state-of-the-art York Compressor. All brackets are made from ?” or 3/16” laser cut steel, and then zinc plated for corrosion resistance.

System installation is straightforward and all necessary components are included in the kits. Although we also offer a variety of parts and components for the “do-it-yourselfer”, we recommend using our complete kits with components that are already tested and designed to work together. We do maintain a limited inventory of our parts, but many are made to order, so please allow approximately 2 weeks for your parts to be shipped.

Simply stated, if you're looking for the best On-Board Air unit available for your vehicle, you've found it!

Our patent pending tri-axis offset design allows for virtually unrestricted movement in three axis simultaneously without any binding.
The design allows you to travel over almost any terrain without any worry. The Max Coupler is designed, engineered, and manufactured to the highest quality standards with a precision normally reserved for military products.

Off Road Armor & Accessories

Kilby's Trailboss line contains a wide variety of body and undercarriage protection. Trailboss parts are designed by off road enthusiasts' at Kilby who put every prototype part through grueling testing before releasing it for production. If you're even thinking of going off road, outfit your Jeep with Kilby's superior protection to ensure that once you get in, you can get back out!

All Trailboss bumpers are made from HRPO (hot rolled, pickled & oiled) steel, which offers many benefits over standard hot-rolled steel. HRPO steel comes from the mill free of internal stresses that can result in poor tolerances in the finished product. It also has a clean, scale-free surface that is resistant to rust and provides a smooth finished surface. Parts are CNC cut and bent to ensure tight tolerances. Trailboss parts ship in custom boxes (many with custom cut styrofoam inserts) designed for a tight fit and maximum protection while in transit.

Quality is built into every Kilby Enterprises Product. We do maintain a limited inventory of our parts, but many are made to order, so please allow approximately 2 weeks for your parts to be shipped. Although the majority of Trailboss products are for Jeep vehicles, we do offer some items for other manufacturers' vehicles. So put your Trailboss armor on and attack the trails with confidence in a Kilby equipped rig!
