well with the help of Kenny theking , in the end of august i should be 3 linked up front and 4 linked in the rear Smiley

since i have a tow rig and trailer now im taking advantage of the that and prepping the truck so that we should have the truck knocked out in 2 days possibly even one
cut out the old shock hoops up front and removed the shocks and lower shock mounts off the axle
cut out the stock mounting points for the transmission x-member and made up a new x-member


got a good chunk of work done today
cut out a stock crossmember in the back and added some cross braces to crossmembers i had already installed on the truck
got the shock towers mocked up then added a truss? to them and made it removeable so i can take the bed off if needed
need to fix the hole in the bed on the drivers side but other than that i think it came out good

got the rear towers all tied in , then started on the front hoops
got the fender wells cut out so the hoops can fit in there then got the hoops all put together

i picked up some hoops from trail gear but they didnt quite work so i ended up cutting the ends off and sleeving them with some extra 2" i had
not sure how trail-gear does it but i couldnt even buy the material for less than they sale the hoops

looking good.

i talked to steve for a little bit the other day about spring rates. i'm running 300's over 250's up front with the collars adjusted down to ride on the 300's at ride height and it rides great. i'd consider something similar for the rear, maybe 250's over 200's.

my current rear setup is 200's with 100's, and its not that great, a little soft. i have the collars on the rear adjusted down to ride on the 200's and i'm not really benefitting from the dual rate because there is not much weight back there (relative to the overall balance of the truck). if i was going to fool around with my rear springs, i'd probably try a single 250, set the ride height, and call it good. i got a feeling that would be ideal since the rear isn't going to really benefit from a dual rate spring setup since you will likely run a center limiting strap.

how high are you setting your shock mounts at full stuff, what ride height/uptravel?  also, do you have a good pic of your steering?  what pitman, TRE, highsteer arms are you running?

I already made your axle bridge.  It looks like this one:

front is set up for 6" up travel and rear at 7" up travel
ride height would be 27" front and 28" rear

stock pitman arm , chevy tre's on the tie rod and high angle tre on draglink and parts mike high steer arm with 1" spacer
if i need to change over to heims or something let me know
ill get some pics later today
yea... i wasn't quite sure how the hoops are going to work out. with you guys pretty much splitting the work. Huh?

curious why you wouldnt think they would work ? i set them for the up travel i wanted and set them so the mounts would be out of the way of the rear upper links and the bridge for the front upper not goin to get in the way of anything Kenny is gonna do

Kenny we may have to modify/notch that bridge for the axle vent and the arb air line/fittings

kenny would know better then i would, but i think the lower link length dominates where the shock hoops go.
the pinion is going to rotate a little differently with links than it does with leafs, and if the shocks aren't straight up and down, the mounting tabs are really going to eat at the mounts on the shock body when it flexes.
the steering setup is also going to dominate axle placement over the lower link mounts, and its going to be a little bit different then a leaf setup as well, because its so crucial for the drag link to be on the same plane with the trackbar.
i don't think the rear is a big deal, but with the front, its hard for me to imagine setting up the shock hoops without having the lower links burned in.

you guys are thinking way too far into this. the hoop will need to be above the lower mount. this will vary from truck to truck. before welding anything solid, cycling the suspension and checking for any possible binding is a good idea. in some cases you will have to have the hoop slightly farther back than the lowers to eliminate binding. but its hard to say exactly how to set this up over the internet. because like i said. it varies from truck to truck depending on how exactly youre building the suspension and how youre mounting the shocks.

its not hard to talk about, its hard to actually do shock mounts without the links on the axle. its already done, so i guess it doesn't matter now.

if they arent right we will re-do them not a huge issue but ill probably be ok

just order springs from summit for the rear 14-250 and picking up the 200's from a guy on DR for $65

all that is left to do on the truck is load it up and head to so-cal in August

the new housing should be in the next couple of weeks , Kenny do you have a way to remove/install bearings on axle shafts?
if not i may have to tear the old axle down then put in the new axle and just half weld in the leaf springs

I have a 12 ton press and bearing splitter. 

So, will the current drag link clear at full stuff?   A 21" frame height at full stuff should work out great and clear the drag link and trackbar no problem.  We won't need to make a bent track bar, too, which is a PITA to make!  How long are the DOM pieces you have?  Also, what all brackets and tabs do you have so far?

Also, are you getting the bump formed housing?  I wonder if we can make Steevos axle bridge work with that?

i forgot to check the draglink for full stuff , right now i have 5-1/4 before the draglink would hit so i could either get the pitman arm from trail gear for the yota box  and grind 3 of the splines so it would fit the steering shaft and lose the 1" spacer , notch and re-enforce the frame or loose the spacer and lower the steering box down

just about everything i have is 40" long except 2 pieces of 2" that are 36"
the brackets and tabs i have are the 2 front lower frame link mount , 2 lower axle link mounts ,shock tabs (4) flat (4) curved , and the panhard axle mount
Steevo said he has the rear upper lower frame mount combo and will get the rear axle lower link mounts
