Question:
If I install the Coil Rite 4175 and use union T/splitter does the pressure reading account for a combined pressure from both? Meaning if it reads 35psi is there actually 35 pounds of pressure in each bag or is it just 17.5 pounds of pressure in each bag totaling 35psi? Yes, I'm totally over thinking this :)

Hey Dan, how did things go with the Coil-Rite air springs and the union tee setup? Did the shared pressure between both bags give you the ride support you were hoping for? Your experience could help others setting up a similar system.
