RETRUE Rear Air Bags Suspension Kit for 2017-2026 F250 F350 F450 — 5,000 lb load-leveling, adjustable 5–100 psi

RETRUE Rear Air Bags suspension kit replaces worn rear springs and gives 2017–2026 F250, F350, and F450 trucks adjustable air support for up to 5,000 pounds of load-leveling capacity.

This complete rear air spring kit is engineered to stabilize heavy loads, reduce bounce, and restore the truck’s ride height and handling when towing or carrying payloads. Designed as a direct-fit replacement for common aftermarket units, the kit works with both 2WD and 4WD configurations across a wide range of model years and fits single- or dual-wheel setups. Parts arrive labeled with clear instructions and pre-drilled mounting points so most installs require no additional drilling.

How will this kit affect towing, hauling, and ride comfort?

The RETRUE air bags increase the rear spring rate on demand, so sagging under heavy loads is reduced and the truck maintains a more level stance. That helps control sway, improves braking stability, and minimizes rear-end bounce that otherwise transmits through the cab. Because pressure is adjustable, you can tune the feel from softer everyday driving to firmer towing setups.

• Up to 5,000 lb load-leveling capacity for heavy payloads
• Pressure range 5–100 psi to dial ride firmness
• Reduces shock and vibration compared with unsupported springs
• Better brake transfer and reduced rear-end sag under load

Will it fit my truck and how simple is the installation?

Compatibility covers 2017–2026 F250, F350, and F450 models across 2WD and 4WD; check the specific year/model notes for certain dual-wheel or lifted applications that may need spacers. Hardware includes pre-drilled plates and clearly labeled parts so many DIYers can install the kit without drilling. For lifted trucks, spacers or slight adjustments may be necessary to maintain proper geometry.

• Direct-fit replacement for many Firestone Ride-Rite style kits
• Pre-drilled mounting plates—no drilling in most installations
• Includes labeled components and illustrated instructions
• Spacers may be required for lifted or altered suspensions

How do I set and adjust the air pressure for best results?

Inflate the airbags within the 5–100 psi range to match load and driving preferences: lower pressure for unloaded, comfortable cruising; higher pressure for heavy towing or hauling. Start with a baseline pressure, then test drive and adjust in small increments until the truck tracks level and feels stable. Regularly check pressures when loads change and before long trips.

• 5–100 psi range for precise tuning
• Increase pressure to reduce sag when hauling or towing
• Decrease pressure for softer ride with light loads
• Check pressures periodically and after long hauls

Who this kit is for: truck owners who regularly tow, haul, or carry varying payloads and need a simple, adjustable solution to restore ride height and control. It’s ideal for F250, F350, and F450 drivers wanting stronger rear support than stock springs provide without a permanent suspension change. Mechanics and experienced DIYers who prefer labeled parts and mostly bolt-on installation will also appreciate the straightforward fitment and tuning range.
