theorhetical suspension lifts........comment please

Theory 1:
Since rock krawler suspension uses a new solid fork for the 3.5 lift that they offer then would it be possible minus the weight issues to say use a coil over lift from fabtech for an f150 or a wrangler to replace the strut and the strut fork on the liberty the top mount as i see now would be the only one that a new mount would need to be created for the bottom since im theorising right could be mounted easily with poly spacers and a single long bolt.

Theory2: creat a linger lower control arm and center mount them lik on the hmmwv to allow to use a longe upper control arm and higher lifts so that you could feasably run 35's if not longer im not a design expert but granted (i was thinking bout this as a was conducting a pmcs on my hmmwv this morning) would it be possible,

It seems like you would spend so much money that you may as well have done a SFA swap. The thought of running 35s on that front differentional would worry me. Just my opinion.

A new knuckle is the first step...one that relocates the upper and lower control arms back to thier stock location...and set the tie rods ends to zero bump steer position. At least JeepAls.com is trying to bring a taller lift to market.

Darby nailed it... the knuckle is our biggest obstacle at the moment. Anyone want to mill up some casting dies for us? :lol:

jason thompson · **Posted:** Sun Oct 07, 2007 4:05 pm

well the rpoblem with theory 1 is that the fork is needed for the CV shaft to pass through
along with that you will need longer knuckle

and I am not quite sure where you are going with theory 2

see thats my point rock kralwers 3.5 x factor uses a solid fork in the front http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?t=10675 so why couldnt a solid longer peice be used.........

and as the theory two the new knuckles would be need but the idead of the longer center mounted suspension would give a longer downward travel in theory as with the hmmwv suspension and yes it woudl be cheaper to do a solid axel swap but if you were just mudding with no rocks the ifs would be better ..........or well according to the army it is since the hmmwv were designed to deal with the mud and ruts of the tundra in russia which is primarily flat.

I think you need a better picture of the Rock Krawler lift, you are only seeing a one sided view of it and it appears to be solid in that picture but is not.

DarbyWalters · **Posted:** Mon Oct 08, 2007 9:51 am

The clevis fork on the new KK Liberty is longer and could be used by someone to gain lift but you still have the problems caused by the orientation on the Upper and Lower control arms...and CV Joint. It makes you wonder if twenty of us got together how the cost would be for new knuckles?

tommudd · **Posted:** Mon Oct 08, 2007 9:59 am

Darby you are so right no matter what we do the knuckle is and continues to be a major stumbling block, and yes wonder what the cost would be if 20 of us got together? It would open the whole lift situation up a lot for sure, a new knuckle and with the possibility of the longer clevis fork from the new one would really help

ah well do you have a better veiw of the fork........also on this note for a 2wd it woudl work feasibly.

the knew kk's how long are their control arms sam length shorter what? and longer forks so you may be able to take the forks off of them and the uppers and use as a lift on the kj any one got a measurement of the two?

I saw an iraqi Police driving a kj the other day i wish i had my camera next time i drive past his checkpoint i ll take a pic.

Your probally looking at about $5000+ per knuckle to cast and possible machining(machining may add about $1000 per),your probally going to need a order bigger then 20 to bring the cost down(probally 2000+ sets needed).Heck it cost SuperLift over $2500+ to cast KJ knuckles(there prototype lift one's,which I still believe you can buy from them for $2500 each) and they have the stuff to do that sort of thing inhouse.

Ok so thats a little more than I have in my pocket right now....so whats next?

Jeger · **Posted:** Tue Oct 09, 2007 5:36 am

I work in a foundry.....and yes it is quite expensive to get a new casting going...no I cannot do it (without getting in trouble.... :twisted:

) Although it is quite tempting, I would need a wax mold the rest I could do myself......

Anyhow I would try to find some existing knuckles that will fit the bill....if possible. Either way (custom knuckle, or knuckle swap) you will have to have UCA & LCA custom made I would think. You would also need to deal with steering and halfshafts. But to find a knuckle that could be made to work would be a huge step forward.

Well has anybody thought of getting the KK knuckles and LCA's and putting them on a KJ.The KK knuckles invert the LBJ so the knuckle is about 1"-2" taller then the KJ's,you'll need the KK LCA also to make it work.Even though it's aluminum it might be worth a try.

Jeger · **Posted:** Tue Oct 09, 2007 11:15 am

Are the mounting points for the LCA to the crossmember the same? If so someone needs to pay Diggerfreek a visit :twisted:

I'm not sure but when I looked over a KK real good it looked the same.

Just need to think outside of the box(I'm ussually about 3 miles to the left :lol:

)
