Determining Lift Hieght

[PasoStepperProject]

Hello all,

I know this is a Really dumb question, but is there a way to determine lift height. I had to get a new frame (hit cattle guard!) for my 76 K15. It has an all spring lift kit. My old frame was stock height. The lift kit looks almost brand new. The springs are shaped like an Eazy Ride type. Not sure of manufacturer. The kid I got it from was clueless. He only wanted the body parts for his low rider. The new truck is almost finished. I need to order shocks but I don’t know how to tell if its lifted 4" or 6". I am pretty sure it’s a 4". I will put a pic in here of the truck riding on stock 31's. I will be putting 35" on it Im pretty sure. My sister works at AutoZone and she gets 65% off so I can get $100 Bilsteins for $35 bucks. I just don’t want to order wrong.

Any help would be greatly appreciated.


Thank You all

Don't know about the lift height, but you can measure for the shocks. Just measure the length from the pin on the frame to mount on the axle and have her go from there

That’s an interesting solution. She is in the warehouse so she would not be able to figure that out but I have the shock length I believe in the description. I will look it up and let you know the lengths.

Thanks for the great idea.

Well I just looked up the Bilstein 5100 series shocks:
Collapsed length is 16.14”
Extended length is 26.15”
Stroke is 10.01”
So after I measure the length between the shock perches what am I shooting for with the truck sitting flat? Halfway between the shock measurements?
I’m sorry to ask suck stupid questions! I thought this would be easier. I am glad to be learning so much from you all. My knowledge on this project grows every day.
Thanks to you ALL!

Yeah, I would shoot for a centered measurement

[PasoStepperProject]

I think my last post wasn’t clear. I know my measurement from perch to perch is center of holes. I am curious if the measurement I get is a middle ground between collapsed and extended shock length or am I totally off?

Thanks

4" front springs are practically flat with a little positive arch. 6" are noticeably arched.

[PasoStepperProject]

Obi with the springs installed or off the truck? The springs have never been taken off new frame. Just replaced axle housings with the one's I had. Put new heavy duty greasable shackles up front. Thats about it. Would a picture of the old frame with stock springs and this new setup tell us anything? Same tires. Thanks for the info.

If your pic up top is without a motor they're 4".

Either way theyre 4s really.

[PasoStepperProject]

No the motor is in. No shocks

[obijuan]

Put your stock rear shocks up front. Those fit 4" lift great.

[PasoStepperProject]

Im replacing all the shocks. I have no shocks now.

[obijuan]

Youre killin me. You have a 4" lift. If youre worried about getting the correct shocks. Stock rear shocks fit great.

[PasoStepperProject]

Sorry to be "killin you". I am only asking cause I am not a senior member and this is the first time I have dealt with a lifted truck.

I apoligize. I will seek some clarifaction somewhere....

best pic i have at reach, these are my 4" tuff country ez rides with a bbc on top.
flat.

Those are some nice shocks. I know you get a good deal, but take a look at offroaddesign.com, as they have some custom valved shocks set up for these trucks. As far as the length goes, you generally need more droop than stuff. It really depends on how you are going to use the truck. See below link to see how to I measured for the shocks. If you are actually going to use the truck, you probably need extended front shock hoops. I bet that 16" compressed length will only give you 1-3" of up travel. Pay attention if you have a SM465!
