if i want to run bigger tires, i need more gear, 8.8 is only good up to 5.13s.

 

you switching it to 31 spline? that pic i posted above of the 9" is my "EB" 9"

 

no im using the EB 9", i was just sayn that if i didnt have it id prolly pic up an Exp. Disc 31sp. 8.8

 

my 28 spline 8.8 has held up real well. the only thing i have broked in the rear end since ive owned the truck was the spider gears.

 

7.5" rear ends have the same shafts as the 28 spline 8.8.

 

its the spiders and gears in a 7.5 that are the first to go.

 

How fast?

 

so, back from the dead.

leafs are out, new plans are here.







all of that, will make me a happy man in the end.

 

schweet!

 

already have a deal on the coilovers, just need to find which coils i want to run. I think im going to stick low and downtravel. who needs fenders.

 

I have some mild coilover tech ill post up when I get to work.

 

DB_1-extended cab 97 style ranger (ExplorerForum) has a combined spring rate of 110lbs/in with a 200tender/250main coil setup making his secondary 250lbs/in (14"x2.5" King's)

Michael- 1st gen explorer 4 door(explorerForum) has a combined spring rate of 145lbs/in with a 250tender/350main coil setup making his secondary rate 350lbs/in (14"x2.0" Kings)

Rick has a different Coilover placement making his spring rates at the coilover much higher then DB or michael, so I didnt include his here.

Equation: Rate 1=A Rate 2= B

(AxB)/(A+B)= final rate

I asked Dave (DB_1) to measure his 14" King Coilovers at ride height. Came to be 28" eye to eye. Fully extended they are 38.5" long. This means that the shock is compressed roughly 10" at ride height. With his spring rate of 200/250, gives him a combined of 110lbs/in. This means for every 110 pounds of weight on the coilover it compresses 1 in. So if I do a calculation out that means each corner on his truck weighs 1100 pounds roughly.

10x110=1100

Now your truck is a single cab short bed correct? so the 1100 is prolly a little high for you. He has an extended cab 4.0L truck so that weight is much more suited to my truck, but it gives you a ball park.

 

Good idea, seems like we are going to same route. One idea would be if your going to use heims to buy rebuildable ones, as the non rebuildables dont seem to last long once they start getting some grime in them.

 

Andrew, What made you decide to go with coilovers instead of an air shock setup.

 

Cost, I would need 2.5's (airshocks) and they are 350 each, then another 400 for a N02 charge kit, total 1100. Where as Coilovers have alot better performance, and I get do a Coilover setup for 245 a shock then coils, so like 900 dollars I can go coilovers.

 

ya i changed my mind on running airshox when i was reading about the extra maintence and parts you would need to adjust them when needed.

Wow, thanks for the info andy. I wish i had a way of putting the truck on a 4 corner scale to weight it. I was trying to figure out what travel im gonna need, then decide on the spring rates that ill need.

Are you stickin with Fox?

 

FOA, they are a new company on the market, they share parts with Kings, but cost alot less. For the low speed stuff I will be doing they should work well.

ahhh, now that ive checked out the site, i see the shock says FOA. kool beans.
