RETRUE Rear Air Bags Suspension Kit for 2011–2016 Ford F250/F350 — 5,000 lb Load-Leveling, Adjustable 5–100 PSI

RETRUE Rear Air Bags Suspension Kit replaces worn rear springs and adds up to 5,000 lbs of adjustable load-leveling support for 2011–2016 Ford F250/F350 (and 2011–2013 F450).

Upgrade your truck's rear suspension with an air ride solution designed as a direct-fit replacement for common kits like the Firestone Ride-Rite 2597. This RETRUE kit fits 2WD and 4WD models of the 2011–2016 Ford F250 and F350, and 2011–2013 Ford F450, and delivers tunable spring rate, reduced vibration, and improved stability without complex fabrication. The system uses durable air springs, pre-drilled mounting components, and straightforward hardware to simplify installation while giving you precise control over rear-end height and handling.

How does this kit improve towing and cargo stability?

The RETRUE air bag kit lets you set the rear spring rate independently by adjusting air pressure from 5 to 100 psi, which helps keep trailers and heavy loads level and reduces squat. That means safer braking, better steering feel, and less sway under load when hauling gear or towing.

• Up to 5,000 lb load-leveling capacity to support heavy cargo or trailers
• Pressure range 5–100 psi for precise tuning under variable loads
• Reduces rear-end sag and improves braking stability
• Works with original suspension to maintain ride compliance when unloaded

Will installation require drilling or special tools?

RETRUE designed this kit to be user-friendly: mounting plates come pre-drilled so most installations avoid additional drilling. The package includes labeled hardware and instructions, but a socket set and a torque wrench—or an impact wrench for faster work—will make the job much quicker.

• Pre-drilled brackets for direct-fit mounting to factory locations
• Detailed instructions and clearly labeled parts included
• Common hand tools suffice; pneumatic tools speed up installation
• Manufacturer support available if you run into questions

How do I dial in the right air pressure for everyday driving?

Start with a moderate pressure and incrementally adjust while loaded to find the balance between comfort and support. Lower pressures emphasize a softer ride; higher pressures increase support and reduce sag—so tune to the weights you usually carry or tow.

• Begin at ~20–30 psi unloaded, then increase for heavier cargo
• Check vehicle level front-to-rear and side-to-side after adjustments
• Use small pressure steps and re-test driving behavior and braking
• Document preferred pressures for repeatable setup with common loads

What components and durability can I expect from the kit?

The kit includes reinforced air springs and stamped mounting hardware engineered for heavy-duty duty cycle typical of truck use. Materials and design focus on resistance to road debris and weather, and the system integrates with the truck’s existing suspension so it can support heavier loads without replacing coils or leaf springs.

• Heavy-duty air springs sized for truck rear-axle loads
• Corrosion-resistant mounts and hardware for long service life
• Designed as a like-for-like replacement compatible with common factory layouts
• Customer support from RETRUE for installation and troubleshooting

Who is this for: This RETRUE Rear Air Bags Suspension Kit is aimed at Ford F250/F350/F450 owners who regularly haul heavy cargo or tow and want a simple, adjustable way to control rear ride height and handling. It suits owners who prefer a direct-fit product that minimizes modification, DIY installers who have basic garage tools, and fleet operators seeking repeatable load-leveling performance across similar trucks. If you need improved stability under load without complex suspension swaps, this kit delivers tunable support for safer, more comfortable driving.
