Air Lift Air Spring Spacers: 2, 4 & 6-Inch Level vs Angled
When a truck is lifted, the distance between an air spring's mounting brackets may change. Air Lift's universal spacer kits can restore the intended operating position of compatible bellows-style air springs, but they are not selected by the lift kit's advertised height alone. The five options here cover 2-, 4- and 6-inch heights in level and angled styles.
Select by actual bracket gap and mounting angle
Measure the rear suspensionPark the unloaded truck on level ground. Measure between the upper and lower air-spring mounting surfaces, and compare that gap with the air spring's design height as directed by Air Lift.
Determine level or angledUse a level spacer for the appropriate parallel mounting arrangement. Angled kits have a 4-degree pitch intended to align certain underframe mounting surfaces.
Confirm the spring constructionThese steel spacers are for compatible bellows-style air springs, including supported LoadLifter systems. They do not fit Air Lift's sleeve-style RideControl springs.
A six-inch truck lift may not need a six-inch spacer. The front and rear lift heights often differ. Air Lift recommends measuring the actual rear bracket separation and reviewing both the suspension lift and air-spring installation instructions before choosing a kit.

Compare the available spacer kits
Use the exact MPN and product photo to identify the correct pair for your measured gap and bracket angle. A kit's height and geometry must suit the installed air springs and suspension arrangement.

Air spring spacer questions
Do all four-inch spacers fit the same way?
No. 52440 is a level four-inch spacer; 52445 is a four-inch spacer with a four-degree pitch. Choose by the actual mounting surfaces and Air Lift's spacer-selection instructions.
Will a spacer fit Air Lift RideControl sleeve air springs?
No. Air Lift excludes its sleeve-style RideControl springs from these universal bellows-style spacer kits.
Does installing spacers raise a truck's rated payload?
No. The spacers adapt a compatible air spring installation to a lifted suspension. They do not alter the vehicle manufacturer's GVWR, GAWR or tire ratings.
Does the spacer kit include air springs or a compressor?
No. These products are pairs of steel spacers with the appropriate attachment hardware and instructions, rather than complete air-spring or compressor systems.
What clearance is required around an inflated spring?
Air Lift's installation manual calls for at least half an inch of clearance around the inflated air spring and mounting hardware throughout suspension travel. Follow all installation and travel-limit instructions.

Always verify the air-spring MPN, lift configuration, alignment, mounting hardware and full suspension travel before installation.
