Call fts they make strut options for the 10-12” kits

 

Thanks I'll try them again - they can be tough to get a hold of! FTS and Cognito were my two lift kit options. Currently still figuring out the details with Cognito

I've been looking at Fox, King, and Bilstein. Just gotta make sure I get the expanded/collapsed lengths correct

 

Well Cognito apparently doesn't have any more information on the shocks they sell with the kit...weird right? I never knew it could be so hard to buy something

Bulletproof says they use a 10-10.5 inch spacer instead of replacing the coilovers...

And FTS hasn't gotten back with me all week...

 

Why not phone cognito and ask?

If you need inexpensive coilobets get foas'

 

Been on the phone and have an email chain with 20+ emails with them...not sure if they don't want to give me the lengths or if it's legitimately information they don't have. They are custom length coilovers and rear struts made for a 10" lift, and they use a cognito part number for a Fox product so it's hard to look up

I don't necessarily need something inexpensive, I just want to be able to research and choose a little bit. This is my dd I'm dealing with so I can't really jack it up to take the measurements with the lift already installed

 

They have the Bilstein shocks on their website for the 10" kit, they use the stock spring and hardware. I'm sure you saw them but why not get those? Do you not have the stock springs/hardware? Also, I found another company who sells the same shocks as well for cheaper than what Cognito is selling them for however I am not sure if their price is for both shocks or just 1 but I'd assume it's for the pair. Both links below.

Thanks A TON - I feel kind of dumb now. I think I was relying on their site a little too much. I saw that one was a 10" shock, I just didn't know if that was the travel or what. I researched the part number all over and it's adjustable for a 10-12" lift which is perfect. I've got all the original hardware too

Now I have to do the rear - cognito is recommending 8" Deaver leaf springs with a 3.5 inch block at the moment. I'm thinking Bilstein makes a rear strut as well, so I'd be looking for the same 10" lift here? (Sorry for the newb questions)

 

This says it works for 5-9" from what I can tell :

http://www.cognitomotorsports.com/bilstein-rear-shocks-1-pair-1500-suv.html (same one again)

See the front will be a true 10" lift from what I can tell - the rear normally rakes ~2inches higher than the front, so I'm wondering if I need a full 10" inch shock in the rear. I'm going for a level rake, so the actual lift should be 10" in the front and I guess 8" or so in the rear (since the rear naturally sits higher than the front)

Also does anyone know how leaf springs/rear blocks mount? Cognito is recommending 8" leaf spring and a 3.5 inch block - does this seem right?

 

8" spring and 3.5" block would be a bit overkill. Basically 8" of lift in the rear should level you out assuming you are set at 10" up front. I'm running 6" Deavers and a 2" block and my rear sits a little lower than my front but I've got the front cranked up about an inch or so. The Bilstein shocks I have out back are part# BE5-6249-H5 and those should be what you are looking for. The ones Cognito has on their website I'm not exactly sure on since they keep the description so vague. They may or may not be the exact same shock I gave you the part# on.

Hope that helps.

 

I agree the 3.5" block and 8" leaf springs should give close to 11.5" of lift. I'm just not sure if they've already calculated in the weight of the truck/sag or anything like that. That's the thing, all these lift companies keep their info really vague, it makes it hard to be 100% sure when your setting it up

Seems like I could go with the 10" cognito front box kit - the front Bilsteins set at 10 (or 11" should be about ~2 of ride height adjustment there). Then with the rear I could go 8" lift (or 9" if I set the front set at 11"), and the 7-9" Bilsteins would work fine (same ones you're running). This seems like the best route by far, thanks a ton for the help man. I'll keep you updated and I'll probably be leaning on you a bit in the future as this progresses lol


I see you have the Cognito 10-12" also, that's gotta be a 2500 though, yea? Super nice man

 

Sounds good. Also one other thing you may need to address for the rear lift setup is pinion angle. You may want to get a tapered block to help correct pinion angle (you can get tapered blocks in all kinds of sizes). I'd call Cognito and get their recommendation on that for your truck.

My truck is actually a 1500. :handshake

 

The pinion angle should match the angle coming out of the trans/tc. Tapered block is just a bandaid for a drive shaft that is too short. That is for a single rear shaft.

Yea Cognito is recommending this exact set-up from my emails/phone calls with them:

1) FSLK101044.1 - front 10" box kit
1) SWAYBAR-8328 - Swaybar - not needed right now so I nixed this from their quote
1) UCAK100047 - Upper control arms also nixed from their quote
1) FOX-FSK-1010DSC-4WD - Fox front coilovers. Way too expensive for my application at the moment. I'll go with the 10-12" front Bilsteins here
2) LSDEAVER-H49 - 8" Deaver leaf - I can get on board with this or the 6". i just don't want a massive rear block
1) BUK10-3.5T-13 - 3.5" tapered rear block kit
2) FOX-FSCAD-10R-1 - fox 8-10" rear struts, I'm going with the 7-9" Bilsteins (what @MotoHead recommended) for the rear


The guy I'm dealing with is just trying hard to sell me stuff I don't need, ya know. And he said all the information he has on shocks is the part number . I'm on the verge of getting someone else to talk to over there, I'm definitely going to need a 2nd and 3rd opionion just to make sure this guy knows what he is talking about. I'm fairly new at this too, so I'm really taking my time and trying to learn here. This is a truck I plan on keeping for the long haul

Just got my rims in too - Ballistic Rage 959 22x12. Gonna plan on running 35" Atturo Trail Blade M/Ts for now. Still researching tires too, I don't plan on too much offroad, just want something with good wear for shitty south louisiana roads lol

 

Also for those wondering - I spoke with Deaver leaf springs. An 6" leaf spring is designed to give 6" or lift, so on and so forth for 4", 8" etc. So adding in the rear block height is an easy way to calculate the total lift of the rear

 

Well yea.

I thought there was a factory block though. Wouldn’t you add the advertised spring lift to the difference in factory and lift block? Maybe I’m wrong it’s been a while since I’ve had a leaf sprung rear.

 

@MotoHead Did you replace your UCAs when you did your lift?

 

I ran the stock UCAs initially and then eventually changed those over to Cognito UCAs.
