I may have to get this swapped out in the near future!

I found this on a 4x4 site.

Tubing Diameter: For light-duty vehicles, systems having discs typically use 3/16-inch line while quad drums often have 1/4-inch line; 3/16 has a higher burst strength to better handle the approximately 1,000-psi pressure required to actuate calipers. (Wheel cylinders function more in the 300-psi range.

A 3/16” solid line will use 3/8-24 flare nuts to make a connection, and can be connected to a Wilwood caliper by installing 1/8-27 NPT to 3/8-24 IF adapters into the calipers.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
