My Z71 seems lower than it should

[OR VietVet]

This is interesting. I've never known of any factory coil to be any color other than black.

IMO, it looks good right where it sits now but you being the owner needs to be satisfied with it.

What are you trying to do with this rig? Just want to lift a little for bigger tires?

Are you liking the level look to it?

I am eventually going to lower my own 2002 at the rear. I like the "leveled" look on these rigs.

By the way, you asked about possibly worn out shocks causing a leveling problem, shocks are designed to absorb spring action and the springs set the height. Unless of course you have adjustable shock spring set ups. Unless of course you have the air shocks. Even a leaking standard shock SHOULD not adjust the height at all.

I do like the level look to it but I want more clearance

I do like the level look but I want more wheel clearance for bumps, dips, speed bumps, and driveways. My goal is factory height and level up the front and some better shocks.

I am not a connoisseur of lifting these independent suspension rigs or lowering them. I know I like the level look and I see you want level but higher all around. How much higher? Do you know after taking the measurements that iamdub/Chris recommended?

Even though it is not a specialty of mine I will look high and low for you once you decide.

My plan is to bring it back to factory spec and then install bilstein 5100 shocks with the builtin front leveling perches to bring the front level with the rear so basically stock rear and leveled front. I just need to find the correct rear Z71 coil spring

I have looked but not given up yet but you may need to use a spring, maybe even the ones that are in there now, and use an insulator.spacer to get the ride height back up.

ebay: says it is oem fit for z71: https://www.ebay.com/itm/2-Coil-Springs-ACDELCO-Rear-Heavy-Duty-VariableReplace-GMC-OEM-19255624/333527998693?fits=Year:2008|Model:Tahoe|Submodel:Z71&epid=112914070&hash=item4da7d160e5:g:O7gAAOSwDkleVqcD

Check ebay. Lots of choices.


Then I found these at RA based off of the oem number-I hope it is right-double check me:

Post your last 8 digits of your VIN and there is a member here that looks it all up for you. I freakin' forget the screen name right now.

I found these and the answered questions said they are Z71 springs, made by Moog: https://www.amazon.com/gp/product/B00498ZR7A/ref=ask_ql_qh_dp_hza


These included spring rates and measurements may help:

@PNW VietVet You are the man, thank you for taking the time to find that for me.

I would still research further and supply the last 8 of the VIN for that member who is a specialist here about the GM parts for your rig. I hope I am right when I guess it is 915_Tahoe that is the member. What I found may still not be the exact stock rear springs. I was saying that the Amazon questions were answered in the affirmative but that does not mean the answer is correct. You might also want to call the MOOG hotline and get with a tech there to reaffirm. I know I would.

I looked out at some other threads and it is 915_Tahoe. Give him the last 8 VIN digits and he can find the oem number to look for or cross reference off of.
