I would keep it stock for the load level system. but for the struts I would go bilstein shocks. they ride great. gmpartsdirect should have the oem load leveler shocks.

 

I used the Arnott Industries refurbs. Go them online from AutoZone with a 20% off coupon code. Cheaper than even Rock Auto. If there's no good coupon code for AutoZone, Rock Auto was the next least expensive when I last looked.

For the front, I also used Arnott but I went with regular ones and their kit has the resistors that plug into the existing harness.

 

I'm going with the Arnott refurbs on the rear, the fronts with the resisters i'm not sure about, do you have a part number? and are you happy with them? how long have you had them on?
I appreciate the help
Thanks

 

Mine has the Z55 Autoride. I did the SK-2806 on the front in June of 2019. I have 43K miles on them so far with no issues. The SK-2806 are the ones where you have to remove the spring from your old strut assembly and move them to the new one. If I did it again, I'd use the SK-2954 so I don't have to swap the springs again.

I did the AS-2708 on the rear. The original rear air bags and pump didn't last maybe 100K miles. I swapped to the Arnott remans at 147K miles. They lasted 9 years / 181,290 miles before they started getting micro cracks and were slowly leaking through those cracks. Installed a new pair on 10/25/2021. No issues so far.

I also have the Arnott pump. It was installed when I installed the rear remans so it has 187K miles on it which was 10 years, 3 month ago. About 5K miles ago, it was leaking air. I tracked it back to a cracked o-ring at the tip of the air suspension compressor dryer. Replaced the o-ring and no issues since.

 

Thanks for your reply Kchevy75,
No one else seemed to know where I was coming from.
I'm going with the SK-2954 on the front.
In your opinion how is the ride difference between this system then the factory system?
Thanks

 

I've had the suburban since 2007 with 7K miles on it. I don't remember the front every being as smooth as it is now with the new struts. No difference in the rear since it's just reman OEM shock absorbers with new air bags.

I priced out different manufacturers for the front but they were more expensive and I had to spend even additional on resistors.
