Front drive line assistance please....

[RCKSQRL]

trying to figure out how much slip you all are running. I have marlins 4" (so I am told) lift springs with 1" lift boomerang shackles. I know that the stock will not work with any flex and I haven't taken it out yet to try. I will be needing to lengthen the fron when I throw in the duals I have but am unsure how much slip I should need safely.

Thanks in advance!

do a little driveway flexin,  if you can see splines  then you are about to pop it out,  only a bout 2 inches shows befor its flopping in the wind

[RCKSQRL]

all fine and dandy, how much slip does yours have?

wondering if the 8" @ marlins would be enough and if so how much is "normally" set for droop ect. That is what I am going for.

thanks

if i'm not wrong its about driveline angle also...

I'm running 31" of slip. Just barely enough.

[Ramrod]

I have 3" of uptravel and 12 of down and have been worried I was gonna pull it apart before.  You really only need about 2" of uptravel though if that.  Just flex it out and messure the distances

31" Holy Crap! Thats, umm.. umm.. thats more then two feet.   My drivelines barley longer then that.

My local driveline shop, which happens to be High Angle Driveline. built me a driveline with 14" slip. I've got the
4" marlin lift with dual Case's. A good driveline shop will have slip stock that they cut to whetever length you need. I would not
recommend the marlin yoke. sorry marlin

Ok, it's more like 25"
Gotta love square driveshafts.

[krawlz]

OK square driveshaft. I get it.

bottom line Maggot, 8" is most likely not enough. Id ask some of your
local guys, who's a good shop around your area and take your rig to them.
I think they would know best for your rig.

[MiniSimp]

yeah, 12" or 14" minimum.

[crapyota]

mine has 3" of compression and 16" of down travel havnt realy flexed it far enough to see the yellow paint i put on the inner shaft's last 3"(square driveline)

[RCKSQRL]

yeah, 12" or 14" minimum.

cool, this is what I was looking for. Thanks all for the input!

If you ever do the rubicon and try the soupcan your shaft will pull apart thats the only place i've ever needed it I can think of

I don't recall anybody saying this is the "soupcan" when i was on the rub. witch part of the rubicon is that?

the marlin slip yoke will work you just have to extend main tube also..
i extended my main tube 4 or 5" but didnt have a longer slip yoke and the yoke would come apart driving over a speed bump. you need both. i went square becuase it cost me $20.  marlin slip yoke and extending main tube will work but looking at $200 plus.   for now i can afford the cheap square and for some reason the trail i run require me to have alot of flex and realy needed suspension droop i know my front drivline useses most of its slip so yeah  16" is about what i need.  sorry marlin when i got the money i will look into it but right now i need to save $$$$ for a marlin hy-steer(spend $ wisely so i can keep wheelin)
