DESCRIPTION

[DOT-CERTIFIED SAFETY & QUALITY] Don’t compromise on safety. Our premium air tubing meets strict DOT standards, providing the flexibility and impact resistance required for heavy-duty towing. Designed to withstand extreme road debris and harsh temperatures without cracking or leaking.

[PREMIUM BRASS AIR FITTINGS] Every component in this kit—including the 1/4" OD elbow fittings, union tees, and Schrader valves—is forged from high-quality brass. Brass ensures long-lasting durability, superior thread strength, and maximum corrosion resistance compared to plastic alternatives.

[LEAK-FREE PUSH-TO-CONNECT TECH] Say goodbye to complicated plumbing. Our precision-engineered Quick-Connect fittings allow you to simply push the tubing into the connector for an instant, airtight seal. This ensures a reliable, hassle-free connection that maintains consistent air pressure in your springs.

[UNIVERSAL AIR SPRING COMPATIBILITY] Whether you are repairing a leak or doing a fresh install, this kit is the perfect match for Air Lift, Firestone Ride-Rite, and other major air bag brands. Ideal for pickup trucks, RVs, motorhomes, and industrial trailer hose connections.

[COMPLETE REPAIR & INSTALL SET] This all-in-one solution provides everything you need to manage your air lines. It includes the inflation Schrader valves for manual filling and the necessary union tees for balanced air distribution across your suspension system.

Fitment Guide

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.
