DOT Airline

When it comes to air suspension, it is vital that you use nylon reinforced DOT airline!  The Nylon strands not only strengthen the tubing, but also make it extremely durable and flexible for years of use!
You should always take precautions to assure your air suspension is safe for daily use.  The last thing you need is to blow an air hose when driving your custom car or custom truck down the road!  

Our Air line/tubing is sold in 10 foot increments
(If you buy a quantity of 1, you will receive 10 feet of the tubing size you choose.  If you buy a quantity of 4 you will receive 40 feet of the tubing size you choose.)
