No drilling required. If you tow a trailer, you know that the load on your rear springs is significant. You lower your trailer onto the 5th wheel, gooseneck, or receiver hitch and you watch the truck squat as the weight settles. Now your truck has that nose-up look like it is having trouble handling the load. Your headlights now point up and irritate other drivers. The solution? Pacbrake air bags. They act as overload springs that are adjustable. You can level your truck with any load. Just add air to the bags through the air fill ports that can be mounted to the rear bumper, or you can automate it with the in-cab switches and gauge kits below: The kits below allow you to control the air in each bag (left and right). There is a separate gauge needle for each bag and a separate switch for each bag. Select your kit from the drop down menu above and to the right.
