My off road called me back on the driveshaft issue I am having after installing the SKY rear shackle flip. He said it would be cheaper to just replace the entire driveshaft and do some sort of double u-bolt set-up (double cardan driveshaft?) on the shaft to make up for the bad pinion angle. He said a lot of jeep guys do this to eliminate bad angles. He said it would be a better alternative then jamming in 10 degrees of chims. To me I am confused, howcome this SKY kit not only destroyed my driveshaft length (to long), but also the angle of shackle is still awful. Everything has gone wrong, and its not cool with me. The guy wants $650 for the install and price of the new shaft. Its complete BS

 

If you need that much of and angle , cut off the stock spring perches and weld them on the angle you need

 

It sounds like BS to me also. When you lift the rear of the leaf springs the pinion angle changes as well, to your favor actually. The sky kit replaces the rearmost shackles/brackets, right? Just in front of the rear bumper?

As with your other thread, if you offer pictures we might be able to help you out a little better than throwing guesses.

Even better if you can snap a picture from the side of the vehicle (camera almost on ground) with a rear tire off so we can see all that is there and get a better picture as to what is wrong.

Because flipping OEM shackles and the sky kit have been done many, many times, without any of the troubles you've had.

 

Just grind off the rivets on your front spring perches, and move them back an inch or two, drill new holes and bolt them back on. Should fix all of your problems at once.

 

to hell with it all guys, Im just putting in 6 inch sky jacker soft ride lift springs, getting rid of the blocks all together, removing the Sky shackle hangers, and welding in the stock rear hangers. Im so pissed off that this shackle kit is anything but bolt on.

 

This still wouldnt really solve my pinion angle issue though would it?

 

Maybe I am adding fuel to the fire by asking this question, but did you install the lift or the off road guy? If the off road guy, what exactly did he do to "make it work"?

 

Depends on witch way your angle is out. It will bring the pinion angle closer to 180* because it will lower the back of the spring a little bit. Your shackle is probably like l right now and it will be like \ when you are done.

 

Love the lingo your using. But actually, my angle is like / . And by moving the front hanger rearward, it would still leave me with an awful pinion angle, and according to them, it needs "10 degrees" to bring it back down. In any event. I was the guy who put in the hangers originally. I put in this rear shackle lift as a last ditch effort 2 months ago to save some money while attempting to achieve a better ride than a block lift. All it did was give me hell. 2 months ago I would of have dreamed about putting in new lift springs, but with my budget as tight as it was, I wasn't thrilled about paying $630 for springs. But now, its just the right thing to do, I have come way to far to use a "cheap way out" shackle reversal flip kit to acquire my lift I desire. I will be able to remove the blocks all together, and have the comfort of using soft ride leaf springs oppose to my stock ones. End of the story.

 

and what about pinion angle? Cause lift springs don't do nothing about it. And honestly I have no idea why you are having such issues, we did a shackle flip on my buddy's F350 a while back and it worked just fine, same with the Sky kit that just went into another buddy's Bronco not too long ago... Where are you located? Maybe there is an FTE member in your area who can come over and give you a hand in all this. Cause to be honest, I do not trust repair shops, remember they are in the business of taking your money, and in this situation lately they have been getting more and more aggressive in that department - to the point where just last week I had to show up at one with a 50-ton big-rig wrecker and threaten the shop owner to either let me take my buddy's car peacefully, or I will first pull his garage door out the wall and then take the car along with the lift that it's sitting on... It's a zoo out there man, so have any shop diagnosis verified by at least one more shop, and ideally at least one friend who can be trusted.

 

Dont weld in your hangers. It will be a real Bitch to change them when they rot out or if any problems occour. 4 bolts are alot easier

 

I wish I could tell you why its been such a bad time with this lift for me. Nothing seemed to be working. I had to tell this shop I wasn't stupid and knew what I was talking about after they were trying to install a double carden drive shaft...I was like uhh no! So I went down there and told them I would rather put in new leaf springs before doing something dumb like that. I told him about maybe moving the front hangers back, but he said the pinion angle would still suck, which is so bad that it would probably still caused a bunch of troubles. The only reason this truck is at this guys shop is because this off road shop happened to be directly across the street from the repair shop that was doing warranty work for me, and I didn't want to get a ticket for driving the truck back on the road without a bed or taillights, so I figured I could buy some time with them finishing the job while I took a break. Anyway, I think I want to just cut my loss with the flip kit, I obviously have something that is different from stock. I think the fact I used f250 blocks may have played a role in this, maybe the kit is designed to be used with your stock blocks. In any event, even if the new springs mess with the pinion a little, at least it could probably be shimmed at that point. I know a lot of you have been on the long journy with me and I deeply appreciate the help I have received. Thank you all.
