When hauling gear or towing, it’s easy for one side to sag more than the other. The Firestone Air Command Heavy Duty Air Compressor with Tank - Analog - Dual Path takes care of that with true dual path control. You can adjust each air spring independently using the in-cab analog gauge with a clean white face. Just push the switch up to inflate or down to deflate until you’re perfectly level. It’s built for frequent use on towing applications and handles varying load capacities, parking angles, and road conditions with ease.
No more waiting around for slow air-ups. The heavy duty compressor delivers up to 150 psi and pairs with a 0.5-gallon air tank for faster response when loads change. It fills from 0–30 psi in about 14 seconds and 0–60 psi in 35 seconds, moving 0.40 CFM at 100 psi with a 30% duty cycle. The tank measures 7-5/8" x 6-1/2" tall x 6" diameter and connects with 1/4" NPT ports. This combo gives you fast inflation for the air springs and even lets you use the included 25' air hose to fill a motorcycle, golf cart, or trailer tire when you need it.
Adjusting air pressure from inside the cab makes a big difference when you’re loaded down or driving through changing terrain. This kit’s pneumatic control panel mounts neatly under the dashboard and works with a single electric gauge that shows real-time pressure. The simple switch setup means you can make small adjustments without stopping or crawling underneath. It’s a clean, mechanical system built for reliability and ease of use.
The compressor features a built-in pressure switch that monitors the tank and cycles the unit on between 90 psi and 120 psi. That means the system stays charged and ready whenever you need to make quick adjustments. You’ll always have consistent pressure to level your air springs or top off a tire, and the compressor won’t overwork, extending its service life.
This Firestone system is made for drivers who regularly tow heavy loads, carry campers, or haul gear. It includes everything needed to manage air spring pressure and maintain a smooth, level ride—heavy duty compressor, ½-gallon reservoir, in-cab gauge, air lines, and hardware. It’s straightforward to install, holds pressure once set, and comes with a 2-year limited warranty for peace of mind on every trip.

Thanks for reaching out Arthur! This is a very light-duty compressor with only a 9% duty cycle, so it is normal for it to get very hot if it has to run for extended periods or repeatedly build pressure. Even a small air leak can cause the compressor to run continuously while trying to maintain pressure, which can quickly overheat the unit. The nonstop running concern points either to a remaining leak in the system, the compressor struggling to keep up or the controller not shutting the compressor off correctly when pressure is not reached. We would recommend performing a full leak test on all fittings and air lines and verifying voltage and ground quality at the compressor. The ECM memory issue is likely because the module requires constant battery power to retain settings. Please let me know if this troubleshooting does not solve the issue.

The preset option makes things so much easier, especially if you're heading out in the early morning for a trip. What kind of 5th wheel are you hauling; toy hauler, 5th wheel?

Thank you for the feedback Troy. As you have already seen, in colder climates, mounting the compressor on the frame rail can expose it to moisture and freezing conditions. Installing it in a more protected location, such as the engine compartment, is a great alternative and can help prevent winter-related issues. What are you hauling around that you needed the extra support?
