What types of regulators can be used on the Shocker?
Most aftermarket regulators that will work on other electropneumatics will function on the Shocker, so long as they can regulate to a low enough pressure and be able to keep up with the necessary recharge rates. The following is a short list of several of the regulators which can keep up (there are more, threse are just some examples): Smart Parts Max-Flo, AKALMP Sidewinder, MacDev Max Attack and Conquest regs, Crossfire preset tank regs, Air America Armageddon, PMI THOR (some users claim this reg can keep up; others do not), Hyper-Flow regs, Bob Long Torpedo, Custom Products regulator.
