2005 GMC Yukon Denali Rear Shock Question

OmarRa · Sep 21, 2024

Hello All,
I just picked up a GMC Yukon Denali XL. Overall the car is clean and drives well. I have to replace the knock sensors next week along with trying to decide what to do about the rear shocks. I checked the RPO codes and it looks like it a Z55. My initial thought was to purchase the coil over conversion kit from strut masters. Rather doing the coil over conversion I would try to replace the air ride shocks. I've seen a few aftermarket shocks available but wanted to see if anyone had any recommendations.

Arnott makes a rebuild with a lifetime warranty. I went the route of passive shocks only to later go back to the stock set up. @Joseph Garcia can give examples too.

Stay with the stock shocks. Rockauto should have those and their is a 5% discount code listed at the top of the home page.

I've had both the OEM Z55 suspension and an aftermarket passive suspension (converted by the previous owner) on my 2007 Yukon XL Denali, and when I converted back to the OEM Z55 suspension, I found it to be a far superior suspension and ride. I will note, however, that some folks on this Forum have converted to, and prefer, an aftermarket passive suspension.

Check RockAuto.com and also check GMPartsDirect.com, enter your VIN, go to the Suspension section, and look for the exploded diagram of rear suspension. You should find what you are looking for along with the correct part number. And, the cost will be significantly cheaper than the local dealer.

Someone here mentioned that Arnott recently changed its warranty to a few years. I don't have specifics but it should be checked out before buying anything so that the buyer knows the options.

Arnotts are worth their weight in my experience! Even though the warranty isn’t lifetime they still make a quality product. I’d buy them again in a heartbeat for the rears on Z55 optioned 2006 XL Denali. I’d buy the fully factory compatible, electronically dampened variants they make next time though. I have the passive shocks, a deal I absolutely couldn’t pass up on them, so I have the passive shocks. They still ride pretty well and haven’t given me a single problem in I think now 6 years, so they’re pretty good product in my opinion. And I’m not exactly easy one the truck’s suspension lol. It’s a working daily driven rig….
