Newbie to this forum, but not new to the GMT800 platform. This is my first post. I have read and searched and searched some more. I used the search function and I've searched this site using google and I cannot fine a definitive answer to my questions.
I purchased our 2004 5.3L Yukon SLT with ZW7 suspension in December 2018 with 80k miles. At the time of purchase, one of the Nivomat shocks was leaking. I replaced the rear springs with GM OEM standard coil springs and installed Bilstein 5100's front and rear. I also purchased a set of GM Z71 coil springs for a possible future upgrade.
Fast forward to 2023. Our Yukon now has 188k miles. The torsion bars are worn, the Yukon is sagging in the front and the ride quality is terrible. I want to replace the torsion bars and install the Z71 springs in the rear.
I read https://www.tahoeyukonforum.com/threads/torsion-bar-tech-101.32545/ . It is an informative thread. In the thread it states "To ID your bars there is a tag on them with a 2 letter code, just match it to the code in the table." I do not necessarily want to go back with the same bars. I want to use torsion bars that were used in the Z71 Tahoe. Can anyone tell me which of the bars listed in Torsion Bar Tech 101 thread were used in the Z71 Tahoe?
Based on this statement in the thread, I believe our Yukon has the "green" keys. "The half ton trucks have the “green” keys in them and the HD trucks the “purple” keys in them. " If I'm understanding correctly, Z71 and non-Z71 Tahoe/Yukon used the same keys. Is that correct? Or is there a Z71 specific key?
Thanks for the help!
