Front drive line assistance please....
« on: May 10, 2006, 12:33:30 PM »
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!

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

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 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.

im running marlins 8in slipjoint and its plenty of slip for my setup... not sure what you guys are running that requires soooo much slip...
My Build 1986 4runner SAS 36s etc

"Later, I learned that even though I engage 4WD my hubs are not automatically locking? Something about manual locking hubs I think. What's manual mean? I need to read a manual to lock them? lol  So I found these neat autolocking hubs and installed them. Sometimes they dont stay locked while I am backing up, but that's fine because I dont have a backup camera to see where Im going (like our RV) so I just simply dont ever back up"- BigMike

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) :twocents:
