Installation
- Difficulty: Intermediate (drilling + routing airline).
- General Steps: Support vehicle; install brackets and bellows; route airlines away from heat/moving parts; leak-check with soapy water; set baseline PSI loaded/unloaded.
- Tips: Maintain minimum pressure when unloaded; re-torque and re-check for leaks after the first 50–100 miles.
For uneven side-to-side loads (slide-in campers, toolboxes), consider a dual-path air management system to set different left/right pressures. Ask us about FFS Professional Installation services.
