Key features

- Leaf mount design
- Lower bracket attaches to the left stack
- Sold as a pair
Leaf mount spacers and clearance
Leaf mount spacers attach to the leaf stack rather than the axle, so the leaf pack and its clamps become part of the mounting system. A taller spacer changes the angle of the leaves under load, which can affect ride quality and the position of nearby parts. Measuring the leaf mounts before ordering helps avoid a mismatch once the vehicle is raised.
Check the area around the spacer for clearance to the frame, brake lines, wiring and the drive shaft. Leaf packs can shift as they age, so inspect the clamps and mounting hardware periodically and re-tighten them when needed. If the ride feels harsher or the spacer appears to lean, take the vehicle out of service until the mounts are checked.
- Check clearance to brake lines and wiring
- Inspect leaf clamps for shifting or wear
- Re-tighten mounting hardware periodically

Vehicle fitment
This 6 in. leaf-mount spacer is universal fit for most Air Ride-Rite systems. Compare the leaf mount and bracket layout with your current hardware before ordering.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Leaf-mounted brackets must line up with the 11.5 in. to 12.5 in. span. Check your existing leaf mounts against that measurement before ordering, since a mismatch means the spacer will not line up.
What’s included
One pair of 6 in. leaf mount spacers.
