took a measurement from frame to body yesterday.......confused

[Sweet Tea Man]

ok, on a 88 fsc, its supposed to take anywhere from a 2.5" to a 3" body drop to lay the body on the ground.

being the frame is supposed to be 7" tall, why did my frame measure to 6 and 9/16"? the frame its self has never been drug on. only the front crossmember and then drag blocks that were bolted up.

and to do the new rails i'll be using 2/4 box tubing 1/4" thick. which in turn would drop the body 3" on a 7" frame. but, from the bottom of the frame to the bottom of the body i'm getting just a little under 3".

did i missread something somewhere? i was using a straightedge along the bottom of the frame and a tape measure to the bottom of the body. i can get pics if you'd like. but just wondering if i misread something:confused: :whatever:

let me see if i can help here...this why you wanted me to call you?? Sorry didnt get around to it...

the actual height of your frame doesnt really matter. The body will drop howeveer far you lower your body mounts down on the side of the frame. So you measured across and got just under 3" right? take that number and lower your body mounts down that far. Then take and weld the 2x4 in place and chop off whatever is left of the original frame on top of the 2x4.

[Beyond Static©]

yea, stock, your body is about 1" from the frame, so you can get rid of a little of that too. You could actually get a 3 7/16" body drop if you put the cab right on top of the frame. You understand what Im sayin?

Doing it this way, do you keep the bottom half of the stock framerail, or do you cut it out completely and just run the 2x4?

Its best to just leave the stock frame there and weld the 2x4 to it. Its easier this way to keep it all lined up and stuff.

[Bagged89chevy]

You keep it and weld the tubing to it

[Mike]

I always wondered how exactly that part of it was done. Thanks for the info Jimmy

jimmy p what size square tube did you run, I am about to start my body drop too, also am I going to have to do a bigger body drop because of 22's?

ive got 2x4 x 3/16" wall. No if you want to lay rocker just do the 2.5". The size of the wheel doesnt really matter as far as how much you bodydrop. You will need to do some tubbing though.
btw I will be doing a quick stock floor how to pretty soon...digging up the pics right now

he wants to lays door. cant wait to see the how to so we can get started. thanks

ohh well then yea you will need to do more of a bodydrop. Probably combine a traditional with a sf to get that low. OR you could channel it.

[Jimmy P]

aight guys i should have it up and running this weekend...just gotta find some time to put it together.

[low86]

what exactly is channeling??????

[mccustomize]

yea I would like to lay door, and me too, what is channeling

[Mike]

Channeling is cutting slots in the floor for the frame to come up into the cab. Do a search for it and NationsFinestRA did a whole write up on his truck when he channeled it.

not as easy as it sounds...i looked into the 1" and its not worth it. not sure if you were serious or not

[Jimmy P]

i body dropt mine 3 1/2 inches and it lays no prob. and the bigger you go on the body drop the less you have to modify the front to get it to lay out on big wheels

yea but when layed out isnt all the weight of the truck on the rockers? Id prefer to have the weight on the frame rails/x-member

[Sweet Tea Man]

not if its done evenly with the frame. thenit would be porportional to the frame and body. they'd be sitting as one

if you lower the cab any more than 2.5-3" it will be lower than the frame unless you trim the rockers off...to lay door or whatever...

[kdubaz]

Hey look, my name in a post :)

I think it'd be cool if we did a bodydrop/channelling/stock floor tech series. Jimmy's stock floor would be one tech, I could eventually do a channelling one, etc.

i got mine started in the tech artichles forum....I still have to add alot but there were lots of people asking em about it so I just threw it together to give them an idea.

Thats a fantastic idea. I remember following along with your channeling project and trying to take notes, it'd be nice if they were all layed out nicely with pictures of the critical steps.

ok so how much of a stockfloor would it take to lay door

[Jimmy P]

i think 5" was about right....but you have to mod the floor for anything past about 3".

[Mike]

Cant stock floor that much, need to stock floor + channel usually.

[mccustomize]

jimmy p, you are laying true rocker right? not the pinch weld

[dropNshaveit]

evan if you match you body to your frame the ground is never level were you park,some part of the truck is always hitting harder than other parts.

[Jimmy P]

jimmy p, you are laying true rocker right? not the pinch weld

cant say 100%...to be honest I dont actaully want to lay any of the body right on the ground. Maybe 1/4" off of it ...even if i have to run blocks. I just dont want to be messing stuff up to be cool and "lay rocker". I did it more to lower the center of gravity and be able to look lower while driving. My front suspension wasnt done yet and still was an inch off the ground. However if you lay a piece of tube across my frame rails it was even with the rockers.
