Will Firestone Air Lift Suspension Kit Fit 2026 GMC Sierra 1500 Elevation X31 With Mono Spring?

Published 10/22/2026

Question:

Hi, Im wondering if this kit will fit my truck. I have the mono-spring rear leaf springs on a 2026 GMC Sierra 1500 Elevation. 4x4, 5.3 V8, x31 off road package, crew cab, short bed. Im having some trouble finding a towing enhancement solution because of the mono-leaf configuration. Thanks!

Hey Jonathan!

Yes, the Firestone Ride-Rite Air Bag Kit # F67XV will work with your 2026 GMC Sierra 1500 Elevation 4WD, even with the composite mono-leaf rear springs.

We've confirmed that the Firestone Ride-Rite air bags are compatible with this type of suspension, unlike some leaf spring enhancement systems that require traditional multi-leaf springs.

The kit includes everything you need, including the air bags, onboard compressor, and wireless controls. It'll help reduce rear-end sag and improve stability while towing.

One thing I'd like to double-check: does your X31 package include a factory rear suspension lift? That could affect whether you need additional spacers.
