Overview

The product is labeled for most Air Ride-Rite systems only, so check compatibility with your air spring setup first.

- Supplied as a pair
- OEM number WR17602373 for cross-reference
Axle mount spacer fit checks
An air spring lift spacer sets the mounting height of the air spring, so it changes how the suspension rides and how the air spring sits under load. Because the spacer is a fixed height, it does not adjust to fit. Measure the mounting points on the axle with the truck at normal ride height and compare them with the bracket distance before cutting or drilling anything.
Air spring lift spacers are often installed alongside new air lines, fittings and fasteners, so inspect those parts while the air springs are out. Look for cracked air bags, worn bushings and seeping fittings. After installation, check the air system for leaks and confirm the truck tracks straight and rides evenly at the chosen air pressure.

Vehicle fitment
No vehicle is named for this spacer. The product carries a Universal Fit label, but a fixed-height spacer with set bracket spacing must match the dimensions of your truck’s air spring mounts.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Measure the distance between your mounting points before fitting, because the brackets are 10.5 in. to 11.5 in. apart. Support the axle with jack stands while the air spring is removed or adjusted.
What’s included
The spacers come as a pair. Air springs and air lines are not part of this spacer.
