Its Baaaccckkk.

i had the silver star 2 link when they first came out with it on my truck...thing was tits for 3 years never had a prob ...its still around on my boys truck...got 14 inches of lift.rode good.never had a prob with my rear either.actually i made the same 2 link my self for another truck.ssc builds some of the sickest shit out there.if your inexperienced at geometry and fabricating go with a 2 link.id run one again anyday....sssc shit is beefy too.there cross brace is like 3/8 thick

So are you saying SSC is inexperienced at geometry and fabricating?

HAHA ! Saw that one comming .

[Clyde@SSC]

What he is saying is a 2-link is easier to install if you dont have the knowledge to setup a 4-link. Its not that hard to understand for most people I guess.

i would say 97% of people on this forum are inexperienced at sus geometry.

I have ridden in a S-10 with a KP 6-Link and a S-10 with a Extensive Metalworks 2-Link with a panhard bar, the 2-Link gets no wheel hop and more lift compared to the 6-Link...

I'm going to be picking a used Extensive 2-Link for now because I can get it for dirt cheap until I can afford a 6-Link... S-10 has been on that 2-Link for years with no issues, not saying its a better design but sh*t will ride better than my leafs with 4" blocks, I get a shit load of wheel hop and vibration...

Im not againts 2-Links everyone on the forum gets too caught up on this whole topic, everyone has their own opinions to each its own I guess...

I've been rocking an EKMW 2-link for almost 6 years now with 0 problems. No drive line vibration, no wheel hop, and it get's half decent lift with my teeny little 2b6 bags

Boyd Coddington's shop made a duelly s10 with a 2 link setup. It was featured in Minitruckin mag a while back.

At that is where you drive at, and that does matter. pinion angle differences as small as 1 degree can cause vibration and premature pinion bearing and transmission failure.

I dont know if its been said yet b/c I dont feel like reading through the rest of the arguing... but for the record pinion angle vs. lift is not a linear relationship.

The amount of pinion angle change with suspension travel (up or down) is equal to the inverse sine of the (height change from the point where the bars are level divided by the link length) for a 2 link.

For this example, the linear relationship is a very close approximation though.



The Height/Length is 15/44 for the example given with the vice. So the part of this graph that we are interest in is roughly (+/-)0.17.

So the point is, this guy is right about it having SLIGHTLY less pinion angle change than if you were to make the level point of the link at the end of the travel range in consideration. More importantly, you will be going from -20ish degrees to +20ish degrees, rather than from 0 to 40ish.

for some reason i have this picture impinted into my memory of seeing a truck bagged in the back with wat i guess u would call a very cheap setup/2 link..
the leaf springs were left in place except the leafs were cut right aftet the axle, therefor the leaf was on connected to the front perch, and then the bags were ontop of axle.. so basically each side there was half a leaf connected to the axle and connected to the front perch, basically the same as a 2link setup correct?

finally figured it out..... a 2 link screws up ur pinion angle if the axle is mounted straight onto the 2 link bars, but if u put a pivot point on the axle and a pivot point on the frame and attach each pivot with a bar, the axle will be able to move stright up and down and not swing as in circle motion, thus keeping a constant pinion angle

if i understand u right u are saying take a regular two link and put pivots on both ends of the bars, now how is the rear goin to stay upright it is gonna just fall over, picture a basket ball on the end of your finger, once u try to move the ball is going to roll off your finger just like the rear will roll back or forward on the pivot on the rear, so u have to put your other hand on top now u can move about, a two link has to be fixed to the rear unless u put a couple of bars on top, wait thats a 4 link

why do you think the bolt on kits sell like mad

[littlelow94dime]

the immortal thread.

[Svaby]

ya well i dind read shit on this thread but i will say a 2 link will do you if you put the bag on the bars and run a pan hard bar... not the greatest thing but it will get you by, i did it for a year or so daily i mean DAILY

[Forklift]

its like a political thread, they dont die and everybody is right and opinions are like asshol..
