Lol....

Frank does know his stuff.

I want to throw in another question.

I have seen many times the statement that the Y-links have a tendency to "unload" dangerously in certain situations. What does that mean? Can someone elaborate?

SeriousOffroad

Me and Chuck go way back. I taught him how to fish.....with his fists.

The weight gets transferred from front to rear...quickly. It happens when climbing a steep grade or obstacle. Awarness of the potential for unloading can prevent serious problems. Some folks simply limiting straps or a single strap at the center of the front axle.

I'm curious about this unloading issue. Unloading the front suspension in this example basically causes the vehicle to roll end over end while climbing the said steep grade?

SeriousOffroad

Depends on the steepness of the obstacle and lead-footedness of the driver.

An example of severe unloading and massive amounts of cranial-rectul insertion:

Truth be told, any coil sprung suspension can and will unload.

That was a good example. Thank you.

Well when Im running 35" tires on 6.5" LA I wont go taking on any near verticle walls so I should be good to go. Someone should of atleast explained how to drive before they let him WOT up that rock. No way that was going to work in his favor.

Hey Frank, so that was an example of unloading right? But would it had made a difference if it was short arms on DBs? I think that vehicle rolled because there was way too much throttle. I mean, it deesn't seem like any type of suspension would've helped there?

UserID6095

Im thinking because with LA you have not only increased the length of the arm but also the circle in which the axle's axis is located. This allows for the stored energy in the suspension to be transmitted in greater detail.

SeriousOffroad

That was an en extreme example of stupidity more than it was of unloading. Way too much skinny pedal.

i found that video before... sucks too cause that was a good lookin ride...

Imagine ratchet strappin your front end as tucked as it will go... park on a hill going up... and then pop the ratchet strap loose...

kinda the same thig if you jump a hill... the bounce affect...

ive never seen this or anything but this is kinda the idea i have in my head of it... would think if it happens... its your own fault...

Thanks! I owe you some Elmers glue and a strip of paper.

That might have been me. I took off my drop brackets cuz they banged on rocks and logs alot, plus i wasn't running enough lift for them to work (4"). With the drop brackets on it rode unbelievably NICE. It also flexed like mad. I would not recommend running drop brackets with 31's or smaller though. The smaller tire gets the drop brackets closer to the ground and bang bang scrape clunk.

I hated myself for taking them off cuz it rode like **** afterwards with short arms but now I'm going with long arms as soon as I get my check and my "mystery" fabricator (in this thread) whips me up some long arms.

huntingman2706217

hhmm... u must have the same mystery fabricator that contacted me lol... one of these days ill have the money to get back with him... lol

I am going to post up a pic of flex on My MJ when it was still street driven. Specs were RE DB's, Stock upper and lowers rusty's 6.5, RE HD trac bar Soa in the rear 33 procomp AT's at Tellico



Here is basically same rig, but with Terra flex LA upgrade, 8.8 with alcan springs. tires were BFG MT's this was at Paragon





Now to throw a monkey wrench in it all... I am currently running a 3 link on a xj and I like it better then either of the setups above. Specs are 4.5 RC springs RK 3 link with bonb proof trac bar, AAL and Shackle rear. 1.5 spacers and 33 mud rovers. Travel limited by shocks being too short.


So the answe is 3 link it. Pro to Db's dont have to cut anything off. Con to any long arm or 3 link, you have to cut off lca mounts.

About that 3-link RK setup, do you think you could get away with not welding the crush sleeves to the frame? I know it says it's recommended but Rough Country uses crush sleeves and they aren't welded in. This is one of the kits I was aiming for but the welding turned me away because I have no access to a welder.
