How low can you go with a 4x4?

[EVRLET]

Do tell how lowering a 4x4 makes it useless?

Apparently you think 4x4 is only for off-roading and rock climbing. What about traction in snow conditions or launches on drag strips. Sure, you may have limited yourself to how you can use the 4x4 feature when you lower it but it’s not useless. I’ve seen trucks with 6” lifts and can’t clear some off road obstacles. Does that make it useless? You probably think lowering a diesel also is useless.

Here’s my 4x4 Tahoe lowered. Torsion bar set up same as NBS. I used adjustable keys to get the front lower than 3”
