Excellent Replacement @ Excellent Price
I purchased these when replacing the front axles on my 2009 Silverado Z71 since I had to remove the OEM shock/spring units. They appear to be great quality and are a perfect fit. Well worth the price.

Do your research
The quick turn around and delivery fro 1AAuto was great. However, I guess I didn't do enough research on this particular shock. They are VERY stiff! Driving over parking lot speed bumps and pot holes will jar your teeth loose. My fault though. Next time I'll know more about what I'm buying

Great Product!!! Perfect fit and match for my Tahoe. Old ones were hard to get out but these went in without a hitch. Why pay those high dealer cost when you can get a better product with 1AAUTO. Best part was the lightening fast shipping!!!

1st time experience
Easy, Fast... within an acceptable price variance of other online auto parts sites... I decided to purchase the products (Shock & Spring Assembly) through 1AAuto. I have been watching videos for years for my minor DIY projects, and I felt it was time to finally purchase the products through them as well. The videos easily make up the price difference as the instructions probably saved me HOURS in the garage... if I had decided to tackle the project at all.

Excellent product!
After receiving an estimate for over $850 to replace both front struts on my 2008 Sierra, I decided to do a little research and after reading all the reviews, purchased the struts from 1a auto. They were an exact fit and the helpful video made it look easy, and in fact it was easier than expected. I highly suggest purchasing these struts for your vehicle especially having a helpful video. Thanks 1AAuto!

Waited too long
My Sierra had 105K on it and the nose was sagging. I have a front hitch to put my boat up a long curved driveway and had to get a 4" raised hitch a few years ago because of it. Wouldn't have had to do that if I had done the struts/springs then, the new Monroe shocks also leveled the backed which had been 3/4" off level.

Great experience
Ordered thes strut assemblies because the didn’t require a spring compressor to re use old springs. Instructional video was awesome and made the job easy and the parts were perfect. This is not the first part I have bought from them and won’t be the last. Great company!!! 10 stars

Rides like a new truck
It all started out with needing to replace my right front axle shaft due to a torn CV boot. After viewing your video it was clear that doing so would required removing the shock towers. I was not happy with how the front original shocks were performing and since even replacing the axle recommended a re-alignment I decided to go with replacing the shocks as well. The video showed me how easy it really was and after the re-alignment my 2009 GMC Sierra with 106K miles rides like a new truck. Great video, even though you forgot to put the dust cap back on. Smile!

I have a lift will these still fit?
Matt S on Aug 29, 2016
BEST ANSWER: Depends on what type if lift you have. Does your model just have spacers on top of the OEM strut plate? If it does then just match your vehicle i the fit list.

2007 ltz Tahoe 4in suspension lift how do I know if I have electric suspension ?
john r on Mar 11, 2017
BEST ANSWER: Every vehicle that GM produces comes with a sticker listing the alpha-numeric codes of all of the vehicle's options. These are known as RPO codes and can be very useful when trying to determine what type of suspension your GM SUV has. There are 3 different "styles" of suspensions that these vehicles come with.

Conventional: there are numerous RPO codes for different types of conventional suspensions, the most well-known being Z71 and Z66. These suspension codes are interchangeable and standard aftermarket shocks will fit any type of conventional suspension. This suspension uses the most basic components: a coil spring or torsion bar spring with a conventional gas charged shock absorber. The Bilstein Heavy Duty and 5100 Series or the KYB Monomax and Gasajust are popular performance replacements. The KYB GR2 and Monroe Reflex and Sensatrac are good quality OEM replacement shocks.

Premium Smooth Ride: indicated by the RPO code ZW7. This suspension uses a conventional suspension in the front, but the rear uses a self-contained, self-leveling Nivomat shock in the rear. ZW7 equipped trucks come with a softer spring in the rear since the Nivomat self-leveling system does some of the work of holding the truck up. Replacing a ZW7 Nivomat unit with a standard shock requires also replacing the spring, otherwise the truck will sag in the rear and have a much harsher ride and potentially dangerous handling.

Autoride: indicated by the RPO code Z55. This suspension system uses electronic shocks in the front that automatically adjust to road conditions, becoming stiffer or softer as necessary. The rear will use an electronically controlled self-leveling air shock that is monitored by ride height sensors and inflated remotely from an on-board air compressor.
Found y'all from your YouTube videos, thank you for those. I'm hesitant to buy these because you don't specify who made the parts. Care to address my concerns (in the age of cheap Chinese "OEM" knock-offs)?
Daniel C on Sep 19, 2015
BEST ANSWER: Hey Daniel. 1A products are good, however these springs didn't work for me. I have an Escalade and need the power springs. Just procrastinating on sending back. Hope that was helpful.
Will these struts work with a leveling kit. Where the block is on the bottom on the strut not a spacer plate up top?
Brett S on Feb 6, 2018
BEST ANSWER: After installing these you won't need to level because when I installed mine a while back my Yukon sits higher than factory shocks.
