But its not completed yet....if you have an F150 I would recommend the www.superlift.com Superlift kit or the www.gorancho.com Rancho kit over RCD. RCD does not lower the diff completely which increases your CV angles.

y2kboti, what are you talking about? Our Drive shafts have U-joints, not CV joints, but maybe the front has a cv joint. And do you mean the transfer case, not the diff? CV joints can handle extreme angles of operation without problems, that's why they use them on short driveshaft Jeeps. And with a lift of this size, you don't need to worry about driveshaft angles, as long as the diff's are inline with the driveshaft. That is the angle that the driveshaft makes with the pinion on the diff. If that angle is the same, you will have no problems. They way to make sure that angle is the same is to take your truck to a competent lift shop. They need to do this adjustment. If they can't or didn't do this, pick a different shop. And 4Wheel Parts is probably the worst at this. Check with others in your area that have a lifted truck and ask where they got it done. And ask about their expiriences. If they have a vibration after lifting, the shop either didn't do an alignment, or didn't check and adjust the pinion angles.

I just picked up an RCD kit this morning and it will be installed Saturday. The kit looked excellent for the price. I`ll post some pics and let you know what I think Sunday.

r0land CV joints are up front. And they cannot handle extreme angles, thats why they wear out so fast.
No, I did not mean the transfer case I mean the front diff. Don't get me wrong RCD does make a quality product but the problem is when you lift a truck you do so by lowering the front suspension and diff. RCD lowers the control arms the proper amount but the do not lower the front diff the same amount. Which results in increased CV angles and premature CV joint/boot wear.

y2kboti, I'm gonna have to disagree. CV joints that are used on drive shafts, NOT on diff to wheel half shafts, can handle extreme angles. On the other hand, I think you are talking about the half shafts, those do not do so well with extreme angles. ANY Independent Front Suspension will have this problem. That is why you break those half shafts if you have a big lift and big tires. The stress is to much. No matter if you go with RCD, Rancho, Pro Comp, or what ever. To my understanding, NONE of these companies drop the front diff. The reason: It's HELLA complex! So, if all of these lifts handle the front diff the same, than that makes your point about RCD being not as good a non-issue. If you want extreme lifts with little to no chance of parts breaking, get a solid front axle. That's it. If you want good ride quality, with the side effect of weaker axles, go with IFS.</font>

christrucker, I understand that you drop the diff to gain the lift but RCD does not drop the diff the same amount as the lower control arms. Thats where you increase the CV angles.

<font face="Verdana, Arial" size="2">All the lift kits for IFS drop the front dif. Thats why the torsion bars have to be droped too, so everything lines up. When you do the lift, you compleatly disconnect the front dif, and put in brakets so its lower. Thats where you get the lift.</font>
