Steve it's a term that has been around hot rodding for many years. It is becoming popular again with 67-72 and 73-87 trucks because it's a means of getting the front of a truck lower.

The term Z'ing comes from cutting the frame and raising a section of it up, effectively lower the rest of it at the same time. This cut and welded section looks like a Z.

It's better described with pictures, so take a look at these from an 85 Chevy truck. This picture shows where the cut was made at the firewall. There was a reinforcing plate welded over the cut section.....

Re: Z-ed

This raises the frame section that the front crossmember is attached to, which lowers the rest of the truck. To make this work, you have to Z the front of the frame where it attaches to the body.....

Re: Z-ed

And the end result is a truck that can set it's frame on the ground with air suspension....
