Need new rear coils for towing?

[SuperDad]

My 2013 Yukon XL 2wd has aftermarket 2" drop rear coils on it. The truck sits pretty level like this, but it sucks for towing. I want to put new rear coils in it. What springs should I go with? I fine with it rising the rear back up to stock. Just don't want lifted rear springs.

Do you have the automatic level rear air shocks, RPO code Z55 I think?

Air bags.

Air bags.

This.


Air Lift 1000 series:

Or Firestone Coil-Rite:

Mine is lowered about 4.5" with Jeep TJ coils and I tow just fine with them coupled with the Air Lift bags.

100% airbags they are cheaper than new springs and work fantastic

Looks like you have the ZW7 premium smooth ride (nivomat) shocks. I have the same on my 2001 and I have the Airlift 1000 bags in my springs. Kept at 10psi when not towing and inflate to about 30-35psi when towing. I drilled a small hole on the 7 pin plug bracket on the receiver to mount the inflation valve. Hardest part was getting the bag inside the spring. They've been on my 2001 since 2007

What about just some some Monroe Airshocks?

I don't think the ZW7 on a 2013 has Nivomats. Thought the Nivomat use ended with NNBS. (?)

Here's a pictures of my Yukon with out the trailer hooked up

Not sure what was in it originally but it now has 2" drop coils springs with KYB Gas-A-Just monotube shock absorber on the rear and KYB Gas-A-Just monotube struts and shocks on the front.

These are the springs on it now: http://mcgaughys.com/products/rear-leveling-kit-30014

Did you do the front and back lowering? Was curious on the ride that it provided after the drop?

Looking to lower my Esky, but want to maintain the factory ride (soft).

 

[SuperDad]

It's a soft ride like this. Only lowered the back so it sits level.

As others have said, the zw7 doesn't have Nivomats. I have a 2011 ZW7, I replaced the rear shocks with Biltsteins and replaced the rear coils with Moog HD springs which are stiffer than the stock springs. This helped a bit but I still plan to add the Air Lift 60769 1000 Series Rear Air Spring Kit so it can handle the load better.

Ok so I installed some new Moog 81069 rear coil springs. Drove around on them for a week, even towed my 5k lb Bronco on a 1500lb trailer. Rode great, handled great weather I was towing or not. Problem is it's now 3" higher then it was with the 2" lowering coils. So I ordered some Moog 81071 and will try them out next week.

Anybody interested in a set of McGaughy 2" lowering coils and shock drop mounts?

 

[Erock7625]

When I installed my Moog 81069 springs it only rose my rear about 1", if you had 2" drop coils I guess it would be 3" higher but only 1" higher than stock. You're still going to be 2" higher with the 81071 springs. Is your front end stock or is it lowered also?

 

[SuperDad]

Front is stock
