cav fab alpha 3 link, pics of install and any issues please?

im in a 99 and considering the 3 link long arm. those that own this who has any install issues? ive seen some close calls to fuel rails and such thought not on 99 like mine.

of those that have this alpha kit, any issues vs clayton
(2nd option) or such.

the rig is a DD, but its time for adjustable control arms and im not sure i cant justify putting money into adjustable uppers vs a new long arm.


thanks for the wisdom all!

Re: cav fab alpha 3 link, pics of install and any issues please?

also the upper control arm is blowing my mind base on the position on the cross member, how the heck does it flex enough at a vertical axis, rather than horizontal, like the LCAs?

thanks again

That is something ive questioned since I first seen the kit. but from what ive read it does good. if you have the dough to drop id go clayton. Iron rock offroad has a nice 3 link, or if you want the absolute beefiest get the ironman4x4fab 4 link setup. it is well built and designed, plus the crossmember is a massive skid plate.
when I go 3 link I personally am going IRO due to price and I have never had issues with their stuff.

This is what I'm running. You can retain the stock transmission crossmember. I'm happy with it, and if you wanted you could run it as a 3-link. I'm running it as 4-link.

i do like the removable cross member on clayton and cav, would you say heims are dd compatable?
i need to find out if these kits will even work with 3.5-4" lift

Re: cav fab alpha 3 link, pics of install and any issues please?

if you are doing a 3 link and using the cast upper control arm mount on the axle... i would recommend replacing the bushing with some sort of hard joint. the single link is resisting all of the rotational force from the axle. throw big tires and deep gear at it, and it wears out quickly. i recommend doing away with the rubber completely for the upper... a 4 link w/ panhard or radius arm inherently have bind on the system that the 3 link removes. but you need a solid joint to control the axle. bushings are needed in a 4 link w/ panhard or radius arm to provide some "give" for the bind.

Re: cav fab alpha 3 link, pics of install and any issues please?

Been running it on my MJ for about 15,000 miles now, Daily driven and on the trail. No issues, no complaints, took about half a day to install and get pinion angle and wheelbase dialed in. Flexes like mad. the upper arm joint had me worried to, but no issues. Check out my CF build for pics. wont let me upload photos.

Re: cav fab alpha 3 link, pics of install and any issues please?

I see no reason why the CAVFab wouldn't work with that lift range. My Rusty's 4-Link is working just fine at 4.5" of lift.

I've ran heim joints without issue on multiple rigs. They can get kind of squeaky, but otherwise have been fine. The rebuildable/greasable type joints are better in that regard.

I just saw these the other day, seem pretty cool. Pricey, but interesting.

As for as the binding of a parallel 4-link or radius arm setup, I think by the time that happens we are beyond what your typical XJ will be flexing anyways. I've never had issues running either setup. My axle will move through its full range of allowed motion with just its own weight, so I don't see binding being an issue. I kept mine as a 4-link because I'd rather have the peace of mind that there are 2 upper arms keeping my axle in place than whatever negligible increase in flex I'd get with just 1 upper control arm. No matter how flexible the front is, the leafsprung rear axle still has to follow the same path.

Re: cav fab alpha 3 link, pics of install and any issues please?

Personally I like the idea of a long arm 4 link -- I'd rather have that extra arm up top just for the security of having 4 point of contact

I've been watching this: http://www.naxja.org/forum/showthread.php?t=1143773

Iron man fab 4 link conversion -- getting info from them on the forum has been difficult but it still seems really well built

They say it is designed around a 4 to 4 1/2 inch lift

Re: cav fab alpha 3 link, pics of install and any issues please?

That looks really cool. The front upper control arms seem a bit odd to me, and they angled the front lowers a fair amount. I'm not sure how that would sit with the stock LCS mounts. Still, it checks a lot of boxes for me. Too bad it hadn't come out earlier.

The ironman setup is awesome. I talked to andy before he built the prototype and he has made some changes to it from his original. if I had the extra money I would get it over clayton any day

cav fab does come with a new solid insert rather than rubber/ poly. they do say it should fit my 3.5 lift and up.

ive read a couple times you all like having 4 arms for security, but how much force is really on the cast diff joint/ upper arm? i would imagine all the brute strength is from the 2 LCA and the upper is simply a guide for the axle.

+ for fab they have tc skid in the future for the alpha

Re: cav fab alpha 3 link, pics of install and any issues please?

another note for the fab is it doesnt require welding though the clayton does, i wish i had a good welder or the skill.

does the fab kit sound like a sturdy mounting system vs clayton that requires welding.

Dutch you'd be a good reference on wether cav is a good choice or worth welding some of this kit. irons is cool but $$$$ big time. greaseable joints are a + for fab. Clayton arms probably slide well, the cross member is smaller, though requires welding.

now all i couldnt pretend to know, but almost all kits are close in price. what each kit delivers is the same or quite different for the coin.

ive heard some good recommendations, however what will these deliver for the money on a dd vs cost and possible 2nd party help on install?

Last thing I want to do is drive over my axle at 70 mph because the one arm stopping the axle from rotating was damaged on the trail I was just on and I didn't know it

Could it happen -- sure

Will it happen -- doubtful

The 2nd upper control arm is just insurance for me -- maybe I'll catch the broken 3rd link before the 4th lets go

Just something to think about...

if you manage to hit the upper link on the trail... you have other problems.

i built my lowers at 36" out of 2x.25 DOM and 1-1/4" heims... bent them. the longer upper with 7/8" heims and 1.75x.120 DOM was fine. it lives in a state of compression as the pinion is driven down under torque. tube carries this load very well.
