Hello, i am new to these chevy trucks and i had a question. Hopefully someone here can help. I recently ordered a lift kit for my truck (2006 Suburban 1500 6 lug 2wd). Its a procomp kit. But when i received it today i noticed its for an 8 lug truck. It comes with the torsion bars, shock extenders, and the shocks. I have contacted the seller and they will get back to me. My question is, how many of these parts also fit the my 6 lug truck? Are the shocks the same? Torsion keys?

Thanks in advance for the help.
