Is there such a thing as front shocks for a Z55 Denali that aren't going to cost me all the gold in FT. Knox?

it seems there is a huge gap in pricing for the front shocks. I have looked on O'Reilly and Autozone and they are wanting $500 and up each. I looked on RockAuto and there are some that are half that proce. Yet I question if it is a quality unit.

my truck has 175K miles, so I am wanting to replace the strut as a unit (strut and spring) and no I am not wanting to disable the system. If I were to do that< i would just bag the whole thing and be done with it. But I'm not at that point just yet. Not sure if I'm going to keep this rig long term. I'm having fun working on the things that are wrong. I'm going to enjoy replacing the top end of the engine in the next month or so.

you could rebuild the struts and save at least some money
all you need is the shock and new springs (presuming the springs have some kind of problem)
the oem shock portion runs about $250 each on rock auto
not sure on the spring p/n, that may be a dealer only part but i know they are out there

I assume the springs are ok. I could rebuild them sure. but was hoping to be able to replace everything. Then again I may not have a choice. Are the rock auto units good quality tho?

At 175k miles, I'd replace the springs as well, since you will have that strut assembly disassembled. Springs will run you ~$70 each.

You may not find available OEM springs, as production of some of them has been discontinued. I ran into this situation, and I used compatible Moog springs with no issues.

Or look for OEM take offs from a salvage place with lower miles. I put 2019 tahoe shocks on my 2008 denali. The ride great, but I did have to put resistors in for the suspension fault. $375 for a pair with 40k. Just my thoughts.

does anyone have any experience with these parts?

I've spent a lot of time trying to make myself pull trigger on either OE Z55 replacements or ditching and going high-end passive's. The only brand indication I see on these struts you've linked is Mac Auto Parts, which looks to be an Ebay parts store only? I've not heard of them but that doesn't mean they're no good? But I did come across this video in my research. Hopefully it helps you see a few signs or features to avoid?


I will co-sign on the advice Doublevie Wes and Joseph Garcia stated above. I haven't made my decision yet on what to purchase but I must soon. Going up to the mountains for ATV trip in 16 days. Now, I'm leaning towards Arnott 2708 rears paired with some nice springs, and "somebodies" fronts, since Arnott does not make an active Z55 front. Maybe this one:


WELL...it looks like there's only 1 front remaining on Rock Auto?


If by chance Rock Auto is out and none of the other appeal to you, rebuilding shock and replacing spring should make for an fine combo

I used the Arnott's to do my rear. Still trying to sort out the front. But I am about to replace the front hub bearing, pads and rotors and axleshafts. may as well do these as well.

Replacing the fronts as a unit with a complete assembly or springs and bushings included means the job can be done in the driveway in 90 min. The other side in half the time because you know how. Having the lifetime warranty is priceless with the way parts have more than doubled in the past 18 months.

Arnott OEM springs were out of stock for a long time. They’re back in stock now. The OEM springs are discontinued or NLA now by GM. Order them now from AutoZone. There’s a 20% off code and free shipping at the top of their page. Today it’s FEBFUN. I just ordered 8 OEM A/C Delco injectors and four A/C Delco o2 sensors. They bungled the order and took off another $50. My final price shipped free with TN tax (6.2%) vs SoCA (8.75%) was $450. That’s unbelievable for OEM.

Pull the trigger while they’re available, keep the z55, guaranteed for life and be done with it, forever. That’s not a word you see that often for a warranty.

ps. If you need other stuff do the order all at once. The 20% discount is good for only one order. You can’t go back later and apply it.

Just curious, what made you want to change the injectors out?

Sorry not trying to take over the thread ...

Running on
e85 it gets P0420 & P0430 DTC
91 it gets P1175 DTC

loppy, intermittent idle and just approaching 170k clicks on an L9H. With that milage and engine run time it can be considered routine maintenance. It's not worth paying for diagnostic time. My Tech2 was poached. This is preventative maintenance against a rich or lean mixture, protecting the cats and improved milage.

Even if, by some slim chance this doesn't clear the DTC, it rules out the injector and o2 issues. That leaves a bad coil(s) or a faulty cat(s). If I have a bad cat, I'd be replacing the injectors and/or o2 sensors anyway. This way, in this particular sitch, I'm simply replacing parts known to outlive their lifespan before they fail. Although they may still function, you don't want an injector to die and kill a motor that's known to run trouble free for 300K or more miles.

This 09 was purchased at 130K three years ago. With no AFM from the factory, running e85 98% of the time, it runs cooler, has no knock/detonation using 100 octane and practically zero sludge in the cylinders as the corn fuel cleans it all out.

Hey B-train, I am in position where i'm being offered a set of 2019 tahoe complete front strut assemblies. I would be placing them in my 2007 Denali. when you put yours, did you need to modify anything other than the adding of the resistors? do you know if they's work with the existing auto leveling suspension that's already on the truck?

They don't work with the auto leveling, but will bolt right in. Probably 30 - 45 minutes for both sides. I did buy the resistors off Amazon for about $55. I haven't had any regrets thus far and have put about 7k on them. I don't think they ride any different than the OEM denali ones.

So I recently replaced the entire z55 suspension system front and rear on my 2011 Yukon Denali and a 2/3 drop as part of a performance upgrade build I’m working on. (Struts shocks, front and rear upper&lower control arms ,ball joints, tie rods etc..)

You can absolutely just replace the front oem/acdelco air ride struts vs the entire coilover assembly and the struts on Amazon Prime via acdelco store with full warranty replacement were roughly 230 each if I remember right?

I’d recommend replacing the bump stop (8.00), upper isolators (12.00) top nut (3.00) basically the worn out rubber parts of the coilover assembly. I ended up doing the entire coilovers including springs based on my goals and it being a long term vehicle for me.

Wondering if you (or someone else) can help me . I need z55 struts, with coil overs, for the front of my 2009 Tahoe 5.3L LTZ. I don't want a conversion. Are they out there?

Everything that I find (arnott, oreilly, advance auto) for the fronts with coils are conversion or 'bypass' struts. In fact I've only been able to find two struts (no coil) for Z55 option: Sachs and Monroe.

The problem with obtaining a set of loaded z55 struts with springs is that the springs for most GM 07-14 truck are discontinued. Aftermarket springs are available but likely not paired with a set of OEM z55 struts.
