RETRUE Rear Air Bags Suspension Kit for Silverado & Sierra 1500 — Up to 5,000 lb Load-Leveling, 5–100 PSI Adjustable

RETRUE Rear Air Bags Suspension Kit is a direct-fit aftermarket air ride system that restores level stance, increases load-carrying capacity up to 5,000 lb, and reduces rear-end sag on compatible Silverado and Sierra 1500 trucks.

This kit is engineered as a replacement for the Firestone Ride-Rite 2430 and is made for 2007–2018 Chevy Silverado 1500 and GMC Sierra 1500 (2WD & 4WD), excluding High Country and Denali trims for 2015–2018, and for 2019 Silverado 1500 Light Duty "LD" models only. RETRUE tuned the components to enhance spring rate, cut vibration transmitted to the cab, and deliver a more controlled ride under load. The package includes pre-drilled, no-drill mounting hardware, clearly labeled parts, and step-by-step instructions to speed up installation whether you’re a DIYer or a professional installer.

How does this kit improve towing and hauling performance?

The air bags give you on-demand support at the rear axle so the truck stays level when loaded. By adjusting air pressure between 5 and 100 psi you can tailor rear spring rate and reduce bottoming out, which helps maintain steering geometry and braking balance while towing or carrying payloads.

• Up to 5,000 pounds additional load-leveling capacity
• Adjustable 5–100 psi range for fine tuning
• Less rear squat improves handling and braking

Will installation require drilling or special tools?

RETRUE designed the kit to minimize fabrication—mounting brackets use pre-drilled holes where applicable and the hardware set is labeled for quick identification. Common hand tools and a basic jack are sufficient for most installs; pneumatic or electric impact tools can speed the process but are not mandatory.

• No-drill mounts included for a straightforward fit
• Comprehensive instructions and labeled parts included
• Automated tools recommended to reduce install time

How do I set and adjust air pressure for best ride quality?

Start at a low pressure to check ride height and increase in small steps until the truck reaches a level stance under load. Use pressure adjustments to balance ride comfort and support—the lower end favors comfort, the higher end gives firmer support for heavy towing or hauling.

• Factory-recommended range: 5–100 psi adjustable
• Lower pressures prioritize ride comfort
• Higher pressures increase rear spring rate for heavy loads

What maintenance and support should I expect after purchase?

Air bag systems require basic periodic checks—inspect for leaks, confirm fittings are tight, and verify hoses are clear. RETRUE provides customer support to answer fitment questions and troubleshooting, and replacement parts are available if a component needs service.

• Routine leak and fitting inspection recommended
• Hoses and valves are user-serviceable
• RETRUE customer support included for assistance

Who is this for: The RETRUE Rear Air Bags Suspension Kit is aimed at Silverado and Sierra 1500 owners who tow trailers, carry consistent bed loads, or want to restore a level stance and improved control without extensive modification. It’s a good match for DIY enthusiasts who prefer labeled components and no-drill mounting, as well as professional installers seeking a reliable, Firestone Ride-Rite-compatible replacement option.
