Frequently Asked Questions About Air Power Line Kits

1. What is included in a 3-in-1 Air Power Line kit?

A standard 3-in-1 assembly bundles three critical connections into one wrapped unit:

  1. Red Air Line: Emergency / Supply line.

  2. Blue Air Line: Service / Control line.

  3. Green Electrical Cord: 7-Way ABS power cable (SAE J560). It also typically includes a hanging clamp (snap clip) for easy suspension.

2. What is the difference between 3-in-1 and 4-in-1 kits?

A 4-in-1 kit includes everything in the 3-in-1, plus an extra Auxiliary Line (usually a single pole or dual pole cable). This is often used for charging liftgate batteries, powering trailer interior lights, or other auxiliary equipment requiring a separate power source.

3. Why should I use a spiral-wrapped assembly instead of separate lines?

Using a wrapped assembly significantly improves safety. Loose lines can easily tangle, drag on the deck plate, or get snagged on truck components during tight turns. The Spiral Wrap keeps everything tight, organized, and protected from abrasion, extending the life of your hoses.

4. Are these kits DOT compliant?

Yes. Victory Technology uses only DOT FMVSS 106 approved air hoses and SAE J560 compliant electrical components in our assemblies. You get the same certified safety as our individual lines, just in a more convenient package.

5. How do I install a 3-in-1 assembly?

Installation is simple.

  1. Disconnect your old individual lines.

  2. Connect the tractor-end fittings (usually 1/2″ NPT) and plug.

  3. Hook up the spring balancer (tender spring) to the integrated hanging clip.

  4. Connect the trailer-end gladhands and plug. We recommend using a Tracker Bar Spring Kit to support the weight of the assembly.
