Could use some instructions on the rear air shock lines. I had to cut the line off of one of the old shocks and struggled to figure it out. I'm still not sure it is right.

Front Struts & Rear Air Shocks Z55 Autoride Conversion Kit - GMC Cadillac & Chevy

Is this a direct replacement for stock

Customer Service

Our 151G-14-4-ASSY passive air shocks fit as a direct replacement. However, these shocks are non-electronic and are considered a conversion for your OEM parts.

Do the rear air shock use the factory air compressor for ride height on the denali?

Customer Service

Hello, Yes the rear shocks are designed to hook right to the factory air lines and will auto adjust from the vehicles ride height sensors and compressor Thank you

Will this replace magneride shocks and struts?

Customer Service

Yes, this is a conversion for Magneride front struts and rear electronic air shocks. Keep in mind you will still keep air suspension in the rear with this kit, however it will be passive.

do ome rear coils need to be changed after installing these rear air shocks

Customer Service

Hello, you do not have to replace the coils, however it would be a good idea to update the entire suspension altogether. With replacing the shocks you will notice a difference in the ride.

how many bypass resistors come with kit 4 or ?

Customer Service

Hello, this kit comes with resistors for all 4 corners; 2 front and 2 rear resistors.

08 ltz suburban flex fuel will this kit work front and back read that flex fuel models have shorter struts than straight gas model this is my 3rd ? ready to purchase soon as I have answers thanks

Customer Service

Hello, unfortunately our conversion parts for front suspension will not be compatible due to the height. The rear shocks are fully compatible with Flex Fuel models.

Will these work for my 2015 chevy tahoe ltz. It has the electronic ride suspension

Customer Service

Hello, thank you for your question! Unfortunately we do not have a 2015 model listed as compatible; these parts will not work for your Tahoe. We apologize for the inconvenience.

Will these work for a 2011 Escalade ESV with the z95 suspension?

151G-14-4-ASSY. Will this set work for my 2009 Chevy avalanche flex fuel? Is the height only an issue with the Suv's?

Customer Service

Hi Ryan, thank you for reaching out. We do not have a kit that is compatible with Flex Fuel model front struts. The rear conversion will work, however Flex Fuel is a different length and our parts will bring your vehicle up about 3 inches. We do apologize for the inconvenience, please let us know if you need anything else. -Stephanie

Will this work with my 2015 Chevy suburban Ltz?

Customer Service

Hi Jc, We do not have these parts cataloged as compatible with a 2015 model. The front struts are going to be a different spring rate on a 2015 Suburban. We apologize for the inconvenience. -Stephanie

Hello, I have a 2011 escalade esv. Do I need to order 4 of these at the 225 cost or does the $225 1 quantity cover all 4 wheels? My mechanic tells me they don't make aftermarket for these and he has to get them from the dealer. Do you have a limited warranty too?

Customer Service

Hello, The parts you are looking at come as a kit priced at $225. This price includes 4 parts total, one component for each corner. These parts are considered a conversion and get you out of electronic suspension; they are a very popular conversion for your model. We included a 1 year warranty on all parts purchased with Suncore.

Hi James, yes this kit will work with your vehicle! The only exclusion for our conversion is Z95 sports package, these struts have a different spring rate and will not function to the quality designed.

I'm looking to replace my escalades front struts, will these replacements work with my vehicle other then the electric ride? Thank you in advance

Customer Service

Hi Sean, Yes this kit is compatible with your 08' Avalanche. This conversion will be for all 4 corners with passive air in the rear; we also include resistors for your dash light. Feel free to reach out with any further questions!

how is the ride compared to the magnetic ride suspension? what is a typical install time?

Customer Service

Aaron, With a standard conventional suspension you will still keep a smooth ride, however your vehicle will be more stiff. The stiffness is actually beneficial for cornering and offers better handling for your vehicle. Conversion is very popular and this is one of our top sellers! Please let us know if you have any further questions. Have a good day, Stephanie

Is this compatible with the 2008 avalanche LTZ with flex fuel

Customer Service

Abe, Yes this is compatible with a 2008 Avalanche! Please let us know if you have any further questions regarding this part or installation. Have an awesome day! -Stephanie

Does this fit all 2009 avalanche LTZ 4x4 5.3 models? If not which are excluded?

Customer Service

Hi Kyle. The only exclusion for this kit is Z95 sports suspension. This package has a lower profile and requires a shorter strut. Please let us know if you need further details!

I see many different questions/answers regarding flex fuel vehicles. Is this kit compatible with my 2008 Suburban LTZ 4wd with the 5.3 flex fuel engine? If not, do you offer a kit for this vehicle?

Customer Service

Hello Mr. Johnson, Good afternoon, and thank you for your interest in our products. I looked into the listing and yes, based on the information you have provided and the fitment guide from the listing, these parts will fit your 2008 Suburban LTZ. PLEASE NOTE THESE EXCLUDES ANY VEHICLES WITH A Z95 SUSPENSION PACKAGE AND VEHICLES WITH WHEELS LARGER THAN 22". and PLEASE ALSO NOTE THAT IF YOU CURRENTLY HAVE A LIGHT, DUE TO A DEFECTIVE AIR COMPRESSOR, OR A LEVEL SENSOR THIS WILL NOT FIX THAT PROBLEM, due that the ECU has to keep reading all the rest of the parts working correctly. I hope this helps, and please feel free to reach out with any additional questions or concerns. Best Regards, Marcelo

So this will raise the front of a flex fuel about 3ich? Does this allow the ride height work? Like if i put some weight on the back end will it still level out

Customer Service

Kenneth, This kit will keep your vehicle at factory ride height, Flex Fuel models are a standard height. You can hook these up to your compressor or manually fill them, either way you should always maintain factory height. Your height sensors are what keeps your rear shocks leveled. If you manually fill them however they will not auto level. If you have further questions please let us know.

will this kit work on a 2015 Tahoe and for the electronic suspension

Customer Service

Hi Jimmy, Yes, this kit is compatible with your 2015 Chevy Tahoe, Your vehicle will require 3 OHM for the conversion. Have a great day. -Tabby

Will this work for my 2008 Chevy avalanche ltz flex fuel model?

Customer Service

Abraham, Yes this is compatible with your model. It is a conversion into a passive (non-electronic) air shock and includes bypass resistors as well. If you have additional questions we are glad to help. Hope you have a good day. -Stephanie

Hi! I got 2008 Chevy Avalanche LTZ 4X4 V8 5.3L crew cab., will this new shock work on my truck? I haul trailer a lot in helping friends moves, lawn service, picking up things or haul other things and lives out in the country off road simple things not too crazy but enjoy the ride and rain? haul ass? With the resistor will I still be able to do all of this? If I hear from you soon that if so that will work then I will order it tonight. Thank you

Customer Service

Hi again Mario Sanchez, Just to clarify the resistors only bypass the active dampening so if you have a failed compressor or other component, you may get a warning. If your factory rear springs are sufficient for your towing requirements, then there is no need to upgrade the rear springs if you feel it needs a stronger rear spring, we have a spring kit available part number 151G-30-R which you can find at the link below. Thank you, - Support at Suncore Industries

2009' Escalade Base Model--Replaced with this part. What would cause the ABS light to be active after install?

I have a 2011 Escalade ESV with the Z95 magnetic ride suspension and 22 inch wheels. Can you please confirm if this system will bypass the Z95 magnetic ride system without any dash warnings?

Customer Service

Hi Raymond, Thank you for reaching out, Unfortunately we do not carry any front struts or shocks for the Z95 suspension code. Thank you, Support
