Arb's Heavy-Duty Air Line Kit
Having long produced the only air-activated locking differential on the market, ARB knows its products well. Furthermore, it knows when to improve upon them. As a result of demand from consumers, particularly those in the heavy vehicle and fleet service industry, ARB developed a new kit to replace the section of blue nylon air line from the vehicle chassis to the differential bulkhead fitting. Though the nylon line has proven to hold up against the harshest of elements and trail abuse, it can fall victim to failure, especially when routed too close to a heat source. The new Heavy Duty Air Line is intended as a supplement to ARB's classic blue nylon line, only running in the most vulnerable areas.
The kit itself features a 1,200mm-long Aeroquip elastomer compound, textile reinforced, high-pressure pneumatic hose. It's equipped with a straight fitting at one end and a 90-degree fitting at the other, and includes the necessary push-in fittings and adapters in addition to a mounting bracket, screws, and a brake line-style retaining clip. The kit has been designed to offer the best in mounting flexibility for use in a variety of installations. It also lends superior protection against any sort of abrasion and flying debris damage. And best of all, it is easily repaired like any soft-compound line in the unlikely event that it does break, a factor that isn't possible when using steel braided lines. We'll be installing the new Heavy Duty Air Line Kit on Project All-American when it's time, so look forward to some real-world test results once we do. In the meantime, look in to the air line. It'll only make your 4x4 that much better.
