Could someone explain the difference to me please? Hate to sound dum put i guess i am about these two suspensions. Never ran one started out on 4 bars and never ran anything else.

2 link, swing arms like the CJ Rayburn deals (unequal length)? with the birdcages clamped to the housing and then a pull bar to hold it all together?

3 link, that one has me confused, birdcages floated or not?

Thanks for any input here, confused.

A 2-LINK AND A 3-LINK IS THE SAME THING, SOME PEOPLE CALL IT A 3-LINK BECAUSE THEY COUNT THE PULLBAR AS A LINK. SO......3-LINK AND 2-LINK IS EXACTLY THE SAME THING.

Ok, one last question, are the birdcages floated or held solid to the rear end housing? If there floated what connects to the top of the birdcages?

on just 2 or 3 links then it is solid. if you put it on a birdcage and float it then you have to add rear bars, or upper bars, turn it in a z link or a 4 link, or you can mkae a wishbone.

they are locked, because there is nothing to hold the birdcages on the top. you can use clamp collars to lock them or you can lock them with welded railing arm brackets, but either way they must be locked.

We run a 3-link and there is a solid bracket welded or clamped on the axle that has a mount for the trailing arms (no birdcages at all), leaving nothing on top of the rearend. Basically you could take your 4link, clamp the birdcages, keep the bottom links connected to the frame on both sides and remove the upper links. Now you would only have 2 links.

Hope this helps.

Yeah, on the 2/3-links the lower mounts are clamped to the rear housing, no birdcage needed. The only difference between the two is wether you have a pull bar or not. (the 3rd link)

Great info, thanks guys.

I was just a tad confused there, never drove one or worked on one so i had no idea what they were about.

Now if you run 2 swing arms and a lift arm, that considered a 2 link? would it work?

IT WOULD BE CALLED A 2 LINK SWING ARM CAR, AND IF TUNED RIGHT THEY ARE JUST AS FAST AS ANY OTHER. WE HAD A 3-LINK SWING ARM ON THE DW8 FOR 2 YEARS AND WON SEVERAL TIMES WITH IT.(PULL BAR CAR)
