How much lift ?
On mine? Not sure. I can measure distances and check my spring rates monday
No worries I was just curious I think I’m happy with it I’ll post some pictures tomorrow of ride height see what you guys think .
Some more progress today on the four link conversion have the truss on almost got all the brackets tacked In place . Pinion and ride height set decided to go three inches back we will see how it goes with the stock tank .
Useing these trans jacks from harbor freight helped with fine adjustments hope I’m doing everything right following ORDs instructions the best I can for anyone trying to do this in the future read read read I’ve read these things front to back a few Times.
I’m worried about my lower link brackets and tubes they seem really low and like I’ll be sliding on them frequently.
150 over 200
Do you carry a spare tire ?
Quick update got the upper and lower links in coil overs lower mount tacked in place . Squareness to the front axel and pinion angle cane out great . Also seems be centered well ,feeling pretty good and pretty optimistic this is gonna all work out . Next I will be putting my hoops in to mount the upper side of the coils and support tubes.
(not the best photographer don’t judge me lol)

Haven’t updated lately but got the upper mounts in it blows my mind the amount of travel you get from these things . Unfortunately I mounted them to close to the frame at driver at full stuff and passenger at full droop I hit the frame . Sucks but it could be worse .

@K30Blazer seat brackets.
Ok guys sorry for the no posts lately I’m not the best picture taker/writer but any how , pretty much got everything and finally set it all down on the springs and I’m sitting about 2” to low from ride height and the amount of adjustment I need is too much to where I believe I’m compressing the spring too far right now I’m at a 150/250 rate and my zero preload measurement wAs 3 5/8 from the nut tho the top of the last thread do that would put my nut distance from the end of the coil would be about 5 5/8 and from what I understand that’s to far so it looks like stiffer springs are in my future .
Do the math in the other thread. Springs are one of those things that its almost impossible to get right when your ordering the stuff. Its really just a guess unless the truck is in your shop and you can weigh the chassis, and calculate the shock angles off that. ORD is really good at guessing to! They know these trucks inside out and generally what people are building for. The biggest question is main spring length. It should be an 18, but I don't know their kit and if its not they probably have a good reason in their design for it not to be. That is, if its the ORD rear 4 link kit you are using. Could be a mistake to, we all make those.
I would venture to guess most linked guys have multiple sets of springs sitting around almost brand new. I know I do, and its just the cost of figuring it out. They're not bad to have around either for the next project.
With that said, I'm reading this last post as you have 2" preload to get to ride height. That's not far off at all. But the spring length is the question. BTW, truck looks good

Thanks man I agree on 18” spring on the bottom did the same method I used in the other post and came up with 1140 lbsDo the math in the other thread.

On each spring so to be at 8” of shock showing I need a spring rate of 1140/8” gives me a spring rate of about 142 needed so I’m thinking a 18” 250sr and a 16”250 I’ll be at 125sr which will also give me some pre load .
The above rates and weight with 1" preload will give you 7.88" of shaft showing per the calculations in https://ck5.com/forums/threads/hard-top-weight-87-k5.339663/.
Which is pretty much perfect, on paper, with a preload of 1.12"
One thing you should have thought about, and shouldn't be an issue with 1 to 2" preload is spring block height. You can calculate this off the manufacturers block height specifications on their spring page. Then use your preload numbers, coilover dimensions, and slider dimensions to make sure you are leaving room and don't block a spring.
Here is where the compromises start. Its all about how much weight you plan on taking and where that puts you in regards to uptravel and downtravel. Personally, if you weighed the truck correctly using what you'd take for the hardest trail then I think you're good. Unless you don't run that stuff as often as you'd like. If the latter is the case then the truck would spend the majority of its time at a different uptravel. Only you can really make the decision to run a different spring based on a different weight. You can always adjust preload, but I don't think that's something many people even bother with. I know I don't.
Some caveats: When I run a hard trail I'm usually taking less weight than when I go camping. So that's my viewpoint. I also have only myself, the driver, in the rig.
The other thing to keep in mind is the actual suspension setup. Coilover angles and the geometry of the links. As well as how the truck feels to you and the biggest one.... Valving! Springs just hold the truck up, valving is everything after that.
Ok guys four link is done can’t wait to get out and use it now only problem I’m having is it really wants to lean and favor the driver side not sure why any thoughts ?
