AccuAir Rear-Only Air Suspension Kit for Jeep Wrangler JK (2"–4" Lift)
Eliminate rear sag for good with AccuAir's Rear-Only Air Suspension Kit for the 4-Door Jeep Wrangler JK. Designed for JK models equipped with an existing 2"–4" lift, this rear-only system delivers automatic load leveling for towing, hauling heavy cargo, camping gear, and overlanding setups—all while preserving ride quality and off-road performance.
Whether you're towing a trailer, loading recovery gear, or packing the Jeep for a long trip, this Jeep JK rear air suspension kit automatically adjusts to added weight, keeping your Wrangler level, stable, and confident under load.
Fix Rear Sag When Towing or Carrying Heavy Loads
Traditional lift kits often lose effectiveness once weight is added to the rear of the vehicle. AccuAir's rear-only JK kit solves this common issue by:
-
Automatically leveling the rear suspension under load
-
Maintaining proper ride height and suspension geometry
-
Improving handling, braking, and stability while towing
The system also levels side-to-side, making it ideal for uneven or off-center cargo.

This Jeep Wrangler JK rear air suspension upgrade is completely bolt-on and designed for garage installation:
-
No cutting
-
No drilling
-
No welding
AccuAir includes a detailed, step-by-step installation guide that walks you through replacing the factory rear coil springs with air springs. Once installed, operation is simple and intuitive.
Push-Button Control with TouchPad or Bluetooth App
Easily adjust your rear suspension using:
-
The included hardwired TouchPad controller, or

When the trail ends, the adventure doesn't. The underbody-mounted 3-gallon air tank provides onboard air to:
-
Inflate off-road tires
