RETRUE Rear Air Bag Suspension Kit for Silverado/Sierra 2500HD 3500HD — Adjustable 5–100 PSI, 5,000 lb Load-Leveling

RETRUE Rear Air Bags Suspension Kit for Silverado/Sierra 2500HD and 3500HD provides adjustable air spring support that levels heavy loads, reduces sag, and improves towing stability.

Designed for 2011–2026 Chevrolet Silverado 2500HD and 3500HD and GMC Sierra 2500HD and 3500HD (2WD and 4WD), this rear air ride kit replaces standard suspension components to give you tunable support for hauling, towing, or everyday driving. The system compresses less under weight, lets you set pressures between 5 and 100 psi, and is built with pre-drilled brackets for a streamlined installation. It’s engineered to be a functional alternative to common OEM-style kits while delivering consistent ride height, improved control, and reduced vibration when carrying heavy cargo.

How does the RETRUE rear air bag kit improve towing and hauling?

The kit adds air springs that support up to 5,000 pounds of load-leveling capacity, limiting rear-end sag and keeping the truck’s frame closer to level when towing or carrying heavy payloads. By increasing effective spring rate, the system reduces bottoming out and helps maintain steering geometry and braking performance under load.

• Load-leveling capacity up to 5,000 pounds
• Adjustable air pressure from 5–100 psi for fine tuning
• Reduced rear sag for improved braking and handling

What does installation involve and do I need special tools?

RETRUE ships the kit with pre-drilled mounting brackets and clearly labeled parts so most experienced DIYers can fit it without drilling new holes. The instructions explain component placement and torque specs; using powered hand tools and an assistant will speed the job and make alignment easier.

• Pre-drilled brackets—no drilling required for most models
• Labeled hardware and a step-by-step instruction guide included
• Automated tools (impact, torque wrench) reduce installation time

How do I control ride comfort and handling with this air spring kit?

Air pressure is your primary control—lower psi gives a softer feel, higher psi increases lift and firmness for heavy loads. The 5–100 psi range covers light adjustments for passenger comfort up to firm support for towing, letting you balance front-to-rear and side-to-side ride height.

• Pressure tuning from 5 to 100 psi for precise balance
• Fine adjustments translate to improved stability when laden
• Helps dampen shock and vibration compared with stock springs

What durability and support can I expect from RETRUE?

The kit is built to withstand repeated load cycles and highway use; components are designed to be a practical replacement for similar aftermarket systems. RETRUE also offers customer support for questions during installation or operation, and stands behind the product with responsive assistance if parts or fitment guidance are needed.

• Engineered for frequent load changes and towing conditions
• Components designed for compatibility with 2011–2026 Silverado/Sierra 2500HD/3500HD
