RETRUE Rear Air Bag Suspension Kit for Toyota Tacoma Prerunner 2005–2023 — Adjustable Load-Leveling, 5,000 lb Support

RETRUE Rear Air Bags Suspension Kit is a direct-fit air helper spring system engineered to add adjustable load-leveling and improved stability for Toyota Tacoma Prerunner and Tacoma 2005–2023 models.

This kit replaces factory helper springs with heavy-duty air bags and steel brackets designed to handle demanding loads while preserving ride comfort. Built as an OEM-style replacement for Firestone Ride-Rite W217602407, the RETRUE set provides an adjustable air pressure range and all necessary hardware for bolt-on installation without drilling. It’s aimed at drivers who tow or carry varying cargo weights and want to reduce sag, improve braking response, and minimize bottoming out under load.

How does this air bag kit improve towing and payload control?

The RETRUE air helper springs let you tailor rear suspension stiffness by changing air pressure, so the truck rides more level under different loads. That adjustment helps maintain better handling and braking when towing trailers or hauling heavy cargo without permanently altering the leaf springs.

• Adjustable pressure range from approximately 5 to 100 Pascal for fine tuning
• Rated to assist up to 5,000 pounds of load-leveling support
• Reduces axle wrap and rear sag for improved stability
• Helps maintain even brake distribution and steering feel under load

What vehicles and model years fit this kit, and how direct is the fit?

This kit is made to fit Toyota Tacoma Prerunner 2WD and Tacoma 2WD/4WD models from 2005 through 2023, with the caveat that 2WD axles are mounted below the leaf springs. Components are designed as a direct OEM-style replacement to match factory mounting points.

• Compatible with Tacoma Prerunner (2WD) 2005–2023
• Compatible with Tacoma 2WD and 4WD 2005–2023 where 2WD axles sit below leaf springs
• Pre-drilled brackets eliminate the need for drilling during installation
• Includes all brackets, bolts, nuts, valves, fittings, tubing, and manual

What materials and build details ensure durability and leak resistance?

RETRUE constructs the kit using rubber air springs combined with SPHC steel plates and heavy-gauge steel components to withstand road stresses and payloads. The design avoids plastic connectors in critical load paths and specifies steel grades for structural parts to resist wear and deformation.

• Durable rubber air springs for flexibility and strength
• SPHC steel plates and 35K-grade steel for brackets and hardware
• No plastic structural connectors in the primary assembly
• Single-use O-rings on fittings—replace after tightening to prevent leaks

How straightforward is installation, and what should I watch for during setup?

Installation is designed to be user-friendly and largely bolt-on: the kit ships with pre-drilled brackets and the full hardware set, reducing the need for fabrication. The package includes an owner’s manual along with inflation valves, fittings, and tubing, but installers should carefully follow torque specs and replace O-rings after initial tightening to avoid air leaks.

• Pre-drilled mounting holes—no drilling required for most installations
• Complete kit includes air bags, brackets, bolts, nuts, valves, fittings, tubing
• Follow manual torque and O-ring replacement steps to ensure airtight connections
• Avoid repeated unplugging of air fittings to reduce leak risk

Who is this for: The RETRUE Rear Air Bags Suspension Kit is ideal for Tacoma owners who regularly tow trailers or haul heavy payloads and want a reversible, adjustable solution to prevent sag and enhance driving stability. It’s a good fit for DIY installers comfortable working under the vehicle or for professional shops seeking a reliable OEM-style replacement for Firestone Ride-Rite type applications.
