LOGIQ RAM 2500 Rear Air Spring Kit (2014+) – Coil to Airbag Conversion

The LOGIQ RAM 2500 Air Spring Kit replaces the 2014+ RAM 2500's factory rear coil springs, or its factory air suspension, with full primary air springs at the rear axle. It's a complete coil-to-airbag conversion, not a helper bag. It's engineered specifically for the RAM 2500 and arrives 100% factory assembled.

It's rated to 8,200lb (approx. 3,719kg) of lifting force and 5,000lb (approx. 2,268kg) of payload capacity at 150psi. It's built for the big caravans, fifth-wheels, horse floats and plant trailers RAM 2500 owners actually tow. Run the pressure down for a comfortable ride when the truck's empty, pump it up for stability under load, and lower or raise the rear for easier hitching and loading. It fits factory-height trucks and lifts up to 3" (approx. 76mm) out of the box, and goes up to 6" (approx. 152mm) with the optional spacer kit.

Our Recommended Setup: AirIQ HD2 + Remote

The air springs can be run with the manual inflation kit included, but most of our full airbag kits go out with the LOGIQ AirIQ HD2 air management system. It has a heavy-duty onboard compressor and independent left/right control from your phone, so you can level the truck in seconds instead of filling each bag at the servo.

We also recommend adding the AirIQ Remote. The AirIQ app is free with every install, but a physical remote docked on your sun visor is a quicker and more reassuring way to watch and adjust your airbags when they're carrying your load. Add the 2-gallon aluminium air tank for faster recovery and extra air storage.

Why Convert Your RAM 2500 to Rear Air Springs

• Heavy-duty load support. 8,200lb (approx. 3,719kg) of lifting force and 5,000lb (approx. 2,268kg) of payload capacity at 150psi.
• Better unladen ride. Lower the pressure and the rear of the truck rides noticeably smoother when it's empty.
• Stability under load. Firm, level support when you're towing heavy or carrying a loaded tray.
• Adjustable ride height. Raise or lower the rear for easier trailer hook-up and cargo access.
• Suits lifted trucks. It fits factory height to +3" out of the box, or +3" to +6" with spacer kit 89-12140-3.
• Direct replacement for factory air. It bolts straight in on RAM 2500s fitted with factory rear air suspension.
• Fifth-wheel friendly. It's compatible with all fifth-wheel hitches.
• Limited lifetime warranty. LOGIQ backs its air spring kits with a limited lifetime warranty.

Fitment Notes

• Suits 2014-onwards RAM 2500 at factory ride height up to a +3" lift.
• For lifts from +3" to +6", add spacer kit 89-12140-3.
• A direct replacement for RAM 2500s with factory rear air suspension. If you're keeping the factory air management system, you'll need a 6mm-to-1/4" push-to-connect adapter (not included).
• Includes a heat wrap kit for the tailpipe.

Never exceed the manufacturer's maximum payload or GVM. Airbags improve load support and levelling, but they don't increase your truck's rated capacity.

Who It's For

• RAM 2500 owners towing big caravans, fifth-wheels, horse floats or plant trailers
• Trucks carrying heavy tray loads, slide-on campers or service bodies
• Lifted RAM 2500s that need load support without giving up ride quality
• Owners replacing tired or failed factory rear air suspension

Frequently Asked Questions

Is this a helper airbag kit?

No. This is a primary air spring kit. It replaces the factory rear coils (or factory air suspension) completely, so the air springs do all the work at the rear axle. Helper bags sit alongside the factory springs instead.

My RAM 2500 has factory rear air suspension. Will it fit?

Yes. The kit is a direct replacement for factory air. You can either run it with AirIQ management, which is what we recommend, or keep the factory air management system, in which case you'll need a 6mm-to-1/4" push-to-connect adapter (not included).

Do I need an onboard compressor?

A manual inflation kit is included, so you can fill the springs with an air line or tyre inflator. For on-the-fly adjustment, we recommend adding the AirIQ HD2 management system, which we fit to most of our full airbag kits.

Will it fit my lifted RAM 2500?

Yes, up to +3" out of the box. For lifts of +3" to +6", add spacer kit 89-12140-3.

Do airbags increase my payload or GVM?

No. Airbags support and level the load, but they don't change your truck's rated payload or GVM. Always stay within the manufacturer's limits.

Can Tough Trucks install it?

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