Professional-Grade Air Line Solutions for the Modern Hauler
When you’re hauling a heavy fifth-wheel or a fully loaded trailer, your air suspension is under immense pressure. A single leak can cause your truck to sag and compromise your steering safety. The RETRUE Air Suspension Tubing Kit is engineered to provide a permanent, professional-grade solution for air line maintenance and repair.

Engineered for High-Pressure Performance
Our air tubing isn't just standard hose; it is DOT-compliant nylon, specifically chosen for its "memory" and resistance to kinking. Combined with our brass fittings, this system is designed to handle the high PSI requirements of heavy-duty truck air bags, ensuring your vehicle remains level and stable even under maximum GVWR.

Easy DIY Installation & Maintenance
We know that truck owners value their time. That’s why our kit utilizes push-to-connect technology. There’s no need for special crimping tools or messy sealants. Just cut your line square, push it into the fitting, and you’re ready for the road. It is the essential kit for every truck's glove box or workshop.
