RETRUE Rear Air Bags Suspension Kit for Silverado/Sierra 1500 — 2007–2019 LD, Adjustable 5–100 psi Load-Leveling

RETRUE Rear Air Bags Suspension Kit is a direct-fit rear air spring replacement that adds adjustable load-leveling and improved ride control for 2007–2019 Silverado and Sierra 1500 models (see compatibility notes).

This rear air suspension kit is designed as a practical upgrade for Chevy Silverado 1500 and GMC Sierra 1500 owners who need better load management, smoother towing, or a firmer rear spring rate without modifying factory components. The kit replaces or supplements the rear springs with bellows-style air springs that accept 5–100 psi of pressure, offering a wide adjustment range to match hauling and towing needs. It’s engineered to fit many 2007–2018 Silverado/Sierra 1500 trucks and select 2019 "LD" models, and it serves as a compatible replacement where Firestone Ride-Rite 2430 kits were used.

What trucks is this RETRUE air bag kit compatible with?

The kit fits 2007–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 two-wheel and four-wheel drive models, excluding High Country and Denali variants for model years 2015–2018. It also fits the 2019 Silverado 1500 Light Duty ("LD") model only. Always check fitment against your specific cab, bed, and axle configuration before buying.

• Compatible: Silverado/Sierra 1500, 2007–2018 (2WD & 4WD)
• Compatible: 2019 Silverado 1500 Light Duty (LD) only
• Not compatible: High Country or Denali models (2015–2018)
• Direct replacement option for Firestone Ride-Rite 2430 kit

How does adjustable air pressure change towing and ride feel?

Changing air pressure adjusts the rear spring rate so the truck levels under different loads and reduces excessive sag when towing or hauling. Lower pressure gives a softer ride with more articulation, while higher pressure increases support and reduces rear squat under heavy loads. The kit’s 5–100 psi range covers light loads, full payloads, and towing setups.

• Pressure range: 5–100 psi for fine tuning
• Lower psi: softer ride, more comfort unloaded
• Higher psi: firmer support for towing and heavy loads
• Helps maintain level stance and improve stability while loaded

How difficult is installation and what tools are needed?

RETRUE’s rear air bag kit includes pre-drilled mounting locations and labeled parts so the majority of installs do not require drilling into the frame. The kit ships with instructions to guide you through part placement and air line routing; standard hand tools and a basic jack are typically sufficient. Using power tools or an impact can speed the job, but careful manual installation delivers the same result.

• Pre-drilled holes and labeled components to simplify installation
• Basic hand tools and jack recommended; power tools optional
• Clear instructions included for mounting and air line routing
• Automated tools can shorten installation time

What performance benefits will I notice after fitting these air springs?

Owners report improved load-leveling ability and a reduction in rear-end sag when carrying cargo or towing. The air springs increase rear spring rate capacity, which helps manage weight transfer and can smooth some rough road inputs. While this kit improves load handling and adjustability, it is not a substitute for chassis upgrades required for extreme towing or commercial applications.

• Improved load-leveling and reduced rear sag under load
• Increased rear spring rate for better stability when hauling
• Adjustable comfort from soft to firm via air pressure changes
• Designed as a bolt-on upgrade without major frame modification

Who is this for: this RETRUE rear air bag suspension kit is aimed at Silverado and Sierra 1500 owners who tow trailers, carry frequent payloads, or want an adjustable rear spring rate to reduce sag and better balance the truck. It’s a practical option for DIY installers who prefer a bolt-on solution compatible with common 2007–2019 1500 platforms, and for drivers seeking a tunable suspension without replacing factory leaf springs or installing complex electronic systems.
