Im planning on getting bds 4.5 la/4 link, ( it says wont work with a manual trans I emailed them to.find out why) and trimming her out and running 31-33's ( depends if I throw a 8.25 under it) I do weekend wheeling, longgggg highway trips for work, is a 4link over kill?

See that's what I said when I was talking to a buddy about it, but then why is all the other ones "radius arms" im trying to figure out if I should go with bds and there "real 4link" or iro 5.5 la " radius arms" suspensions get so confusing.

The iro kit will flex better because a ra is close to a 3 link... More links = less flex
To answer the q, yes its a good idea to do la 4 link instead of sa 4 link

More links = less flex? what????(double triangulated 4 link)
I would do a 4 link especially if driven on the road because with a radius arm setup you only have 2 rod ends holding your axle to the body in sted of 4 way to scary for me.

Ya less links is more dangerous if a failure happens, and a dt 4 link in the rear it awesome but a 3 link up front is the s***

If your talking a true three link agreed 100% seen some good ideas.

That clatons pro kit is lagit

I have rock krawlers long arm kit. Three link in front flexes like a gymnast. Triangulated 4link in the rear flexes way more than leafs but if you drive a lot on the hwy keep your leafs. it'll be a better hwy driver with leaf springs. You can always add the 4 link after if you wheel more.

I feel bad for people that are looking for real advice and have to read through this bs.

hawaiian808

See haha, I read that a 4link is better because it keeps proper geometry while inter extreme flex,

and that a 3link radius arm setup "pulls the axel back as it flexes "

Also why the hell is a bds 4link long arm 2800 bucks!

ktmracer419

yup.

ANY longarm will flex more than necessary. you will be limited by other things long before the arms limit it. and at that point the flex is hurting your capability.

and in my opinion IRO is garbage.

they gloat about how its the flexiest system out there and all that. lets see how it works on the trail when the factory 10mm upper link bolt or that cheesy caster adjuster fails.

and thats just the tip of the iceberg lol.

Not trying to hijack, just trying to understand. Someone said the stock Qudra-link or whatever it's called is a 4 link setup, correct? I take it the "4 link" refers to the upper and lower control arms? If this is the case, does a 3 link kit just eliminated the 2 UCA and replace them with a single unit that mounts to the top of the front diff?

Gee oh Dee

I see an awful lot of radius arm setups on an awful lot of XJs.
