LOGIQ - 2020+ Chevrolet 2500 Air Spring Kit

The LOGIQ Air Spring Kit for the 2020+ Chevrolet Silverado 2500HD and 3500HD is a leaf-assist rear airbag kit built for heavy towing and hauling. It mounts between the frame rail and the leaf pack, replacing the factory overload springs if your truck has them. The result is better load support, more lifting capacity and a noticeably more comfortable ride in the cab when you're towing a big caravan, fifth-wheel or plant trailer.

LOGIQ uses dual rolling sleeve air springs tuned to match the ride frequency of the front suspension, so the rear of the truck works with the front instead of fighting it. The kit is rated to 6,400lb (approx. 2,903kg) of load capacity at 150psi. It arrives pre-assembled with vehicle-specific hardware, and installation needs no drilling or welding.

This listing is for the air spring kit only. It includes a manual inflation kit so you can fill the bags with an air line. For on-the-fly levelling, we pair these bags with the LOGIQ AirIQ HD2 management system and the 2-gallon aluminium air tank. That's the setup we fit to our full airbag kits.

Why Fit Airbags to Your Silverado HD

• Serious load support. 6,400lb (approx. 2,903kg) of load capacity at 150psi for heavy caravans, fifth-wheels and tray loads.
• Better in-cab comfort. Dual rolling sleeve air springs are tuned to the front suspension's ride frequency for a smoother, more settled ride under load.
• Replaces factory overloads. It mounts between the frame rail and leaf pack, with an overload spring removal kit included.
• Adjustable to the load. Run pressure anywhere from 5psi to 150psi, low for an empty truck and high for a loaded one.
• No drilling, no welding. The kit is pre-assembled with vehicle-specific hardware for a clean bolt-in install.
• Fifth-wheel and gooseneck compatible. It's confirmed compatible with the OEM fifth-wheel hitch and the B&W GNRK1020 gooseneck hitch.
• Limited lifetime warranty. LOGIQ backs its air spring kits with a limited lifetime warranty.

Frequently Asked Questions

Does this kit include a compressor?

No. This is the air spring kit only, with a manual inflation kit for filling the bags. For in-cab or phone control, add the AirIQ HD2. It's the system we fit to our full airbag kits, and it's our pick whenever an air tank is part of the setup.

Will it fit my lifted Silverado HD?

Yes, with a 1–3" rear lift you'll need to add bump stop spacer kit 88-32200-3. You'll also need at least 1.83" (approx. 46mm) clearance between the tyre sidewall and the leaf spring, which is worth checking if you're running wider wheels and tyres.

Does it fit dually (DRW) trucks?

Yes, but dual rear wheel trucks need a separate DRW hardware kit. Get in touch and we'll make sure you get the right parts.

I've got a long-range fuel tank. Will it fit?

No. The kit isn't compatible with aftermarket fuel tanks. Contact us with your setup and we can talk through options.

Can I still use my fifth-wheel or gooseneck hitch?

Yes. The kit is confirmed compatible with the OEM fifth-wheel hitch and the B&W GNRK1020 gooseneck hitch.

Can Tough Trucks install it?

Yes. Book a fitting at our Arundel or Mackay workshop and we'll take care of the install.
