A RETRUE air bag kit helps support heavy loads, improve balance, and reduce sag, but it does not change your vehicle manufacturer’s official towing or payload ratings. Always follow your truck’s factory-rated limits. This phrasing is consistent with RETRUE’s positioning of its products as helper springs and load-leveling support systems.

Yes. RETRUE air helper springs are designed to reduce rear-end sag caused by trailer tongue weight or bed cargo, helping your truck stay more level for improved stability and control. RETRUE’s collection pages repeatedly describe the kits as solutions for rear sag, load leveling, and towing stability.

No. RETRUE states that the kit includes two inflation valves, one for each side, similar to tire valves. You can inflate the system manually, although an onboard compressor can make adjustment more convenient.

When lifting the vehicle by the frame, RETRUE says air pressure should be reduced to a low level but kept above 5 psi. Because exact operating pressure can vary by kit and vehicle, always follow the instructions in the specific installation guide for your application.

RETRUE’s current FAQ says yes: its air springs are designed and tested to handle demanding conditions, and the company states they can withstand pressure spikes from bumps and uneven terrain. Still, the best practice is to use the pressure needed for proper leveling on your specific vehicle and load.

For some models, yes. RETRUE says spacer kits are available for certain applications, and customers should check the installation guide to confirm fitment for a lifted vehicle.

RETRUE presents its air spring systems as straightforward to install and provides installation manuals, videos, and technical tips. Many product pages also emphasize no-drill installation, though the exact process depends on the vehicle and kit.

RETRUE recommends mixing 1 part liquid soap with 4 parts water and spraying the solution on the air line fittings, air spring, and compressor body or head if a compressor is installed. If bubbles appear at the fittings or air line connections, re-seat, re-cut, tighten, or seal the connection as needed.

You can, but RETRUE says it reduces side-to-side leveling and allows air transfer between the two sides, which can reduce stability. That is why most RETRUE kits do not include a T-fitting by default.

Not necessarily. RETRUE states that the air helper spring mainly assists with loaded rides; if your vehicle rides rough when empty, it may still ride fairly rough even with the kit installed.

RETRUE directs customers to choose a kit by vehicle year, make, and model. The site’s air suspension collection is organized by specific truck applications including Ford, RAM, Toyota, Chevy, GMC, and Nissan platforms.

RETRUE says customers should contact customer service with the part number and quantity needed so stock can be checked, or purchase replacement parts through a local retailer.

Yes. RETRUE states that if a product or associated parts are defective or missing on receipt, it will repair, replace, or refund the defective part at no charge to the original purchaser. The warranty is limited to the original purchaser and is non-transferable.

Not always. RETRUE says manufacturing defects may be covered, but issues caused by misuse, over-extension, rubbing, excessive pressure, suspension design problems, or fabrication issues are not covered.

RETRUE’s refund policy says returned items must be authorized first and must be returned within 30 days of receipt, unused, in original packaging, and with proof of purchase. Returns should use a tracked shipping method.
