I ordered a 150psi fixed CO2 regulator from them and got incredible service.

I ordered it over the phone, they took all of my info including my email address.
They sent me an email later the next day with a PDF file attached, which was my invoice. They tried to send me my UPS tracking number but the email bounced, so they actually called meto tell me that the email bounced and to give me the tracking number.

I have ordered several hundred, maybe thousand at this point, dollars of aftermarket items from all of the major Nissan aftermarket manufacturers, and havent gotten anywhere near the service I got from 4x4rockshop.

They emailed me, called me, the item was shipped out and I received it, all exactly when they said.
Great company I highly recommend them!!
