Thanks for the reply. A couple things.. The ZR2 HD sits about 1.5in higher in the rear from factory. I did 3.5 cranks on the torsion bars to help get it closer to level (now it's about .5in higher). Even though 3 cranks is pretty minimal, it seems to have stiffened up the front end and it's a bit more harsh than I would like over bumps. Curious if this Cognito kit would help performance / premature wear with this in mind.
I have also heard (on a diff forum) that it may be better to just roll with the Cognito spacers and pitman/idler braces (sold separately) - to leave out the UCAs as they are not necessary.
Thx for any additional insight
