thanks

some more info thanks to kunar-

i just got a really good deal on a set of skyjacker 4" lift coils (thank you jrmustranger) but strangely enough they are giving me more like 5" of lift.

and some random info from bobby walter on rrorc-

the 23 in xj coils i use smash to nothing in 160 trim on the ttb, maybe 3 in of lift, the 225 are better and supply @ 1 in more lift in the same situation....this should be @ 2 in more in your application. the 8 in are @ 275 and give an additional 1 in of lift...but are actually shorter then the 160 coils @ 1/2 in free length.

very soft. huge difference in trail performance with the ttb. iirc you and potts were behind me on the tight green run on the turtle hills, with regular ttb coils that would have flopped me all around and required frequent back ups with the long wheel base. these springs eliminate that, but its hell on the steering linkage.

i have used fullsize 150 coils for a 79 and they are better then the lift ttb coils by far but not as good as the xj coils. i have noticed most like the variable rate coils on the straight axles, i dont at all on the ttb...

Maybe he got 6" coils instead?

He does have an STX....maybe that effected the way it lifted his truck?

rick 15x7 rims 3 3/4 back space, 33x1250 tires.....

the beams have been cut and turend at the lower bj's so it dose make them a tad wider than stock come to think of it.

I should have my truck back toghter by tomorrow(got invaded with ants today and put a bite in to my plans).and Ill re-measure them. if you like.
but Im 97% sure they meassure 15 15 1/4

My 6" coils are around 7-8 years old. They measured almost exactly 19" free when they were new, and haven't lost any height that I can tell.

I had SJ 4" coils in there before these, they were 17" free, and needed huge spacers underneath them to be at a full 4" lift height (right now with the 6" coils, I'm at a true lift height of around 4.5")

The 6" coils have 12¼ windings, the 4" ones, 11 windings (wire size appears the same, but didn't check it). The 6" ones were noticeably softer.

o.k. short recap for 6" skyjacker rbv's #136 435ppi 19"free
2nd gen reg-15"(new)
3rd gen reg w/winch-15" (8years)
1st gen super-15 3/8"(new)
2nd gen super-14.5"
3rd gen super-14.5"
b2 v8, bumpers-14.75(few years)
b2-16"(new)


4" skyjacker rbv's #134 480ppi 17"free
gen1 reg w/winch-14.5"
gen1 super-15"
gen3 reg-12.5-13.5"?

it seems to make sense except for junkie and critter coming out even?(the first two)but one has cut and turn and the other runs a d44ttb-not exactly conventional.
either way once i get skyjacker and duff to confirm their rates i'll know if i want to use spacers on the duff coils,4" jackers, or cut and extend my coil buckets for the 6"ers.(which seems the best of the rbv spring world)

i use my truck too much on highway and load it down and haul too much for the softer eb or xj coils,and the super runner setup cost is out of range as of now.so thats why i'm dicking with these coils that a simple drop arm will tolerate.

still not many with the 4"ers piping up?

To add to the list my old SJ 6" measured 14.5" loaded, on my old 91 SC ranger.

Rickcdewitt, I'm very interested in this post, becuase I too have a reg cab, and am looking to stay within the 3-4" lift range....having a tough time doing research. I keep jumping between the duff and skyjacker kits.....

Edit: Looking at skyjacker, their kits seem a little more suited for a work truck/wheeler.

 

[rickcdewitt]

lets keep it on topic,i'll pm you.

Oh, I was just basically cheering the post on. Not trying to jack the thread.

Rick, my springs meassure 19 inches total,free lenth.sorry about that.

and a total of 13 complte loops and about one and half two inches left over. going from the bottom of the spring, from pig tail end to pig tail end.

Should have the front end back on the truck tonight,with the wheels on the ground, and Ill get you my track width from the outside to outside of the tire's,and messure the spring ride heigt.

Ill try getting a over all free lenth pic of the springs with a tape running along the side of them while I still have them out...

If you have any other question on the springs, feel free to ask, as they are not hard to pull back out at this time.

That shouldn't matter unless there's been a significant change in the axle's width (my D44 is basically D35-width).

ouch,sorry to be a dick. could go on for days on the suject of what lift to buy though,just keepin er on track.i did find out the 4" jackers are 480 ppi-way too stiff.and the 3.5 duffs are 17" free length(i checked today) which is the same as the 4"skyjackers and give more travel with their lower rate.better off with spacers under the duffs or raised buckets and 6" jackers to get 4"s i think

don't make me rush you over some stupid inter-q's and don't take the pics if its a bother,thanks though.my trucks track width from the outer edge of the tires is about 71" or a little more i think.

not much you're right.and with his 15x7's it should be almost full height (6") or yours a little lower i think.i did notice that a difference of about 2" or so track width(rim width) per side will make a half inch or more difference in ride height on my truck when going from 31's on 15x7's, to 33's on 15x10's.
but its also hard to say how much the coils skyjacker sells differ in 7 years time,who knows.
