Rear lift springs???

[ErocksAHoeFoSho]

I'm just getting started looking into lift ideas for my 2016 Tahoe but it seems there are only spacers available to lift the rear of the tahoe in the 2-3" range? Does no one make aftermarket springs that lift the rear 2-3"? I plan to 4-wheel my Tahoe a little bit getting to some dispersed camping areas and I like the idea of having better articulation/wheel travel in the rear suspension but if spacers are the only choice then I guess that's what I will use
I had a tacoma before my tahoe and jeeps before that, so the lack of aftermarket is definitely frustrating. Thank god for this forum though... tons of good info

I think lifting the rear with new, longer springs vs. spacers is an absolutely wonderful idea!!!
I looked at doing this myself, when I put the 4" lift on. There were so many other purchases going on at the time, like new wheels and tires, that it was hard to justify the additional cost of new rear coils when there was nothing wrong with mine. But, it's still in the back of my mind. If and when I need new rear shocks then I will certainly be swapping the spacers for lifting coils.
I came across this company months ago and spoke with a rep. They provided a quote to me for a pair of rear coil springs providing 3" of lift. I think it was around $350-500. Coil Spring Specialists out of Kansas.
Poke around their website but I think reaching out to them will get you answers the quickest.

Good info, thank you! That's definitely pretty steep for some coil spring... I will probably just go with spacers for now and hopefully the aftermarket will get better as these trucks get older

there are several good spring manufacturers around that can do it, the issue is maintaining ride quality as well. i assure you., it will be trial and error getting everything correct. Companies that offer these parts do R&D...

not saying dont do it, most likely if they are reputable, they will come very close and you would never know with out trying a slightly different spring. For example...

If some one can measure a Z71 Hoe and Suburban (for info) it would be nice to see axle to frame height...the Z71 has a 300# stiffer rear coil. That should offer some lift to a non Z71 suspension. ST.Louis spring in Missouri does good work as well.

i even know some have reached out to Eibach and the likes for a custom spring.

I am looking at doing something like this on mine so I can get better travel. Right now I have a longer springs but, my kit has shock, control arm and panhard relocation brackets. My plan is to use the stock mounts and the Spohn off road kit and a custom set of King shocks. I am still working out the details and parts.

A longer spring and a longer stroke shock sound like a good idea. Be sure to check clearances and drive shaft angles before you get committed. I think you will need longer control arms and panhard bar so you can get everything adjusted and working.

This is my rear suspension setup, Z71 coils and 2” spacer gave me the perfect 4.5” height and factory ride and rake for heavy loads….. front is just a 3” spacer. Has 7k miles on it and love it. So does the wife

@Rockcrawler11 - Are you saying that the z71 rear coils springs gave you approx. 2-2.5" of rear lift alone?

That’s what it looked like to me when I installed them. Seems closer to 2” than 2.5”…. When I’m home in a few weeks I’ll take a measurement. Even with a 3” spacer up front I still have a 1.5”-2” rake at the rear…. I also have a non autoride model.

 

[STORMIN08]

if it did gain the 2", that alone is enough for me to swap and eliminate the coil spacer i currently have

You keep the factory ride and add capacity too from the higher spring rate… it’s an OEM+ upgrade that works perfect.

Is it a higher spring rate or a longer spring? Or both?

 

[STORMIN08]

on this forum, someone found the info...i only recall it being a 300# increase, thus less sag. no mention of length

Does anyone know the part number for the z71 suburban rear spring?

 

[Tahoe14]

DId you try putting in your vehicle information at Rock Auto.

 

[Fifty]

I did. But it lists about 10 different springs. I have a Yukon Denali and im installing ADS coilovers in the front and their piggy back shocks in the rear.
So my plan was the z71 springs since they are supposed to lift the vehicle a little. (And put Firestone air bags in them so I can retain the air assistance)

 

[Oh Kee Pah]

Try GM Part# 23154235; for the SUBURBAN z71 rear coil.
It will possibly referred to as "Rear Spring Assembly" or "Rear Spring" or "Rear Coil Spring"

Purchase example here: https://www.gmpartsstore.com/oem-parts/gm-spring-assembly-rear-23154235?c=az0x

 

[Fifty]

Awesome. Yep. Ordered those… and they are on back order
…smh

 

[Oh Kee Pah]

Great!

So...after I looked up the Suburban z71 rear coil, I started thinking about the increased rear ride height from the z71 specific coil. I provided you the Suburban part# and when I looked at vehicle fitment, it only listed the extended bodies, NOT Tahoe or Yukon. I then went back to the Suburban coil springs and went to the basic LT rear coil. When I looked at fitment it showed Yukon, Tahoe, Suburban, XL and Escalade extended body.

WOULD THE SUBURBAN z71 REAR COIL PROVIDE INCREASED RIDE HEIGHT ON A TAHOE/YUKON COMPARED TO THE z71 TAHOE/YUKON SPECIFIC REAR COIL?

 

[Fifty]

I imagine it would. Every where I looked, the Z71 suburban coils were back ordered with unknown eta.

Then a birdie told me about some springs o'reillys sells made by performance spring.
They sell two versions. It looks like a tahoe and a suburban version. ill post pics in the next post. I need to find them. It has the specs
