Long leaf

[dirtydon]

So i searched the past threads if this has already been covered then i apologize
im installing a chevy 14 bolt rear and a 8 lug 10 bolt front axle going with hummer wheels and 37.5 tires and im looking it to a long leaf soa im looking for the springs to be 8" longer and softer than the 4" lift springs on my jeep thru the internet ive see info about using stock xj rear leafs front and rear on the cj
has any one used suburban stock front leafs for the same application. i found a company called holbrook speciaties that offers kit for $650 but do to the axle swap ill have to fab most of my own brackets anyways so if any one was done this swap or purchased that kit any info would be appreciated before i disable my jeep again.
Thanks, Dirty Don

85 CJ vs a Suburban?

There is only one way to do this correctly and that is to have some springs built............lots of folks have swapped in junk yard springs for length and came up with mixed results after spending countless hours fabricating brackets......Why ? because the spring weight rating does not match both of the vehicles.

Weigh the corners of your Jeep with the new axles , tires and whatever weight in gear and passengers that will be normally present......that should also include fuel , a winch and spare tire.......determine what length spring you want for your chassis package , along with the width and thickness of the leaves and center bolt offset if any.........with this info in hand , call someone like Jeff Deaver in Los Angeles or Bill at Alcan in Colorado .....and start your conversation there.......with the information in hand they will build you a spring that will be spot on the first time around. No guessing and Yes it will cost a little more......but you'll only do it once.

I agree with Tarry, as that would be the right way to get it right the first time around.
But If you want to mess around with junk yard springs, here's a link to a chart as to how long different ones are and what kind of offset they have.

I am using xj springs on mine on all four corners, bought from jc whitney with 2" lift. they were 6 pack set, I am using 4, I am sprung over, with a shackle reverse in front. I replaced my shackles with sliders, I have 5" bump stops. I like this set up, I have so much drupe on the front that I had to build my own front shaft
