Rc silverado front lift and skyjacker rear lift coils

[87carl]

Has anyone here used skyjacker c25r or c50r rear lift coils in a 2007-14? They are made for the 2000-2006 suburban and tahoes. C25R lifts 2.5 inches c50r lifts 5 inch.
As far as I can tell the 2007-14s rear suspension is same as 2000-2006 and other replacement or heavy-duty springs are advertised as 2000-2020 or 2000-2014. so I think they should fit but want to make sure they do. Also anyone who has used them any year range how is ride quality and towing capacity? How much actual lift did you get. Thank you

@87carl I cannot speak on these specific springs but there are other springs that are made for both generations of Tahoes. Moog 81069 for example is a Z71 replacement for both the 2000-2006 tahoe as well as the 2007-2014 tahoe so those skyjacker springs should fit just fine just need to decide which height you need to go with.

@Tozan Was just asking about buying the Skyjacker lifted rear springs the other day. I think he will be interested in this.

After seeing this thread I just ordered a set of the c25r's. I'll update when the arrive. They said they were in stock, so we'll see.

Let me know I will be ordering the same ones tomorrow and everything to completely rebuild my front and rough country lift struts to lift front 3.5 inches.

That's what I was thinking. We will see how they fit and lift it. I just don't want its rear to sag but don't want to much rake. lifting front 3.5 so figure 2.5 in rear should keep it close to level and will use timbren suspension enhancing bumpstops to prevent sag while hauling stuff hopefully that will be good enough

That sounds interesting I wonder if they come in different spring rates. I need a set that can handle 1850 lbs. for my rear. and I also need to be able to bolt them into place top and bottom so they wont fall out if I over flex it...

I have not seen anything on spring rates. I wanted to know that too because I haul feed and building materials and pull a car trailer regularly. how do you plan to make them bolt? Would a plate over the top and bottom coil that bolts to spring pads work? I like that idea better than limit straps. Mine is a long way from needing either. I'm in the middle of a complete remodel of a house that sat empty 9 years so truck and hotrod have very small budgets right now. In a few years hopefully it can get more interesting. I need to replace most of my front end before inspection next month so talked the banker (wife) into letting me do a cheap mild lift while I am replacing almost everything. Cheapest lift is obviously rough country not the best but should get by for a couple of years. Stupid thing is they don't sell a 3.5 knuckle lift with struts for suvs only trucks so the kit will only do my front and hopefully the rear shocks. that's why I started searching for springs I hate using spacers or blocks I have had bad experiences with them off road

 

[Tozan]

Yea I am not a 100% sure of the execution of what I will be doing I might have a race truck fabricator to do mine.

 

[87carl]

I ordered
rough country 11932 3.5IN GM SUSPENSION LIFT KNUCKLE KIT (07-13 1500 PU 4WD) with the n3 rear shocks and lift struts.
Skyjacker c25r rear springs
Mevotech tough terrain- outer tie rods, wheel bearings, upper and lower control arms with ball joints and sway bar links.
Stock replacement- inner tie rods, cv shafts, brake pads, calipers, rotors, dust shields and brake hoses
moog alignment bolt kits and rear spring isolators.

Still need to order inner tie rod boots and probably longer rear sway bar links.
Not everything needs replaced but enough does that I figure rest probably won't have alot of life left so might as well get it done now while I have it apart and before I get it aligned. I hate doing an alignment and then have another part go few weeks later needing another alignment after replacement. Most I ordered from rock Auto and will be here tomorrow rear springs will be a week, rest between. Also gotta get two tires so I can move rears to front and put new in rear fronts are bald from bad parts and alignment. tires are 60 dollars more than they were last year

One question I have not found answer to is will stock rims fit the rough country knuckles without a spacer? I will probably get 1.5 front and 2 inch rear hubcentric spacers just in case I need them but would prefer to avoid them.

 

[Tozan]

Stock rim fitment: RC should be able to answer that question it may even be on their web site.

Couldn't find it on their sight and they haven't answered my email yet

I found this on Rough country's site for that lift kit. Also if you go down farther you will see what wheels will work depending on tire and rim sizes too.

Notes - Important

• Requires cutting and grinding
• If using factory wheels, a 0.25in wheel spacer is required. #1065
• Does NOT work with aftermarket control arms
• Does NOT fit GMC Denali models with Magnetic Ride Control.
• New lift block replaces the factory equipped block.
• If truck is equipped with a mass damper on the front differential, the damper must be removed.

Thanks I didn't see that part

Overall I'm impressed with the quality of the springs so far. Powdercoating is solid and spring rate seems a bit stiffer than what I had but appropriate and not uncomfortable. I'll drive then and update with ride height measurements.

 

[87carl]

How well did they fit? And curious to see the measurements you get. Mine should be here I think Wednesday

 

[Parabellum]

Fit is great. Measurement is not accurate as im using these in combination with a spacer. I might purchase the 5 inch coil to test without the spacer.

How big of spacers do you have? And did you have spacers in before putting the springs in. Let me know if you do try the 5 inch spring

 

[Tozan]

What is the free length of the springs? A friend gave me a set of springs from a chevy lift kit and they are about 20.75 inches tall. I wonder if they will give me the lift I am after without using any spacers.

 

[87carl]

The rear springs wheel bearings and outer tie rods came in today so that means I finally have almost all my parts. I only need wheel bearing bolts which will be here tomorrow excited to finally tear it apart and swap everything. theres a big pile of suburban parts in the dining room lol and couple nights ago while I was getting beams to jack my house off it's foundation a dodge ram found its way to my driveway I couldn't resist I love 3d gen dodges and it was cheap. I gotta replace a ball joint and a tie rod in it tomorrow but that gives me something to drive while the suburban is in pieces and it makes my old dodge a parts truck so I can steal it's motor for my dart because I need more projects and things to do lol I will measure old and new springs and struts and measure wheel well hight before and after see how much actual lift I get. And I gotta put back together and do breaks on one of my extra cars so I can sell it to get new tires for the suburban and new dodge

 

[87carl]

Kinda layed stuff out and loosely mocked them up to see what everything looks like and how things fit together. control arms and tie rods are olive drab green not yellowish tan lol it looks kinda nice with all the black parts surprised how heavy some of these parts are. Also I have new brake pads calipers and rotors to put on all the way around went with 1.5 front and 2 inch rear spacers gotta trim front wheel studs slightly mostly just the tip and maybe 1 or 2 threads. Can't wait to see how the suburban looks with this stuff on it and most importantly how it handles.

 

[Dustin Jackson]

@87carl I'm excited for you let us know how it goes, are those lift knuckles?
