I currently have a 6-8 inch CST lift on my 01 Z71. I intend to replace the rear blocks with lift springs. However, I am also considering going with ORD's Rear Shackle Flip Kit which gives you 4 inches and then using a shorter lift spring. ORD doesn't currently make this exact bracket. I had talked to them awhile back and they said they are working on it. They have one for the 2000 and up 2500s and 3500s. Apparently you can make these work with some modifications, but its not a direct bolt up like the rest of the kits.

What would the advantages be with this flip kit compared to a higher lift spring? Keep in mind that this isn't just a drop hanger, it changes the shackle from tension to compression mode. Will this give me better articulation than just a higher lift spring?

Finally, if anyone else is interested in doing this, we might be able to motivate them to put this into production if we had about 10 orders or so. Price should be around $180.

I just found DEs post in the drop hanger thread. Can't wait to hear how it goes. There is one thing I forgot to ask. What is the effect of not dropping the front of the spring? This has to shift the axle forward. Does this mean that the tire is no longer in the center of the wheel well. Could you use this with a front drop hanger to minimize the forward shift?
The flip kit also has to affect the pinion angle. But isn't this actually a better angle since you are running a lift?

I think it does sometimes help w/ pinion angle. Also, theres zero rate add a leafs on the offroaddesign.com site that is made just for this application. you can move the axle back an inch or inch and a half to make up for the movement foward. it bolts straight into the leaf pack just like an AAL but at the same time acts like a block in that it add an inch to the height and not affecting the spring rate. its a must have when you do the shackle flip. Ive seen a pic of a tahoe with a shackle flip and the axle was moved foward a lot...and looked like ass.

Ok heres the deal, I THINK all you have to do for the HD flip kit to work is drill some holes, no big deal. I can confirm this as early as next week. It does move your axle foward a little but the zero rate aal will move it back to position. Ill get pics of it up asap, it should get top my house about monday or tuesday.

I had forgotten that their zero rates had a one inch and one and a half inch shift holes. Kind of strange that the guy at ORD I talked to didn't mention them when we discussed the flip kit. If I am going to have a custom spring made anyway do you think they can include the offset center pin in the design so that I won't have to use the zero rates?

DE, since the flip kit bracket is angled to properly relocate the shackle forward of the original mounting point to accomodate the rotation of the spring as it drops, How in the hell are you going to determine where that would be? I am assuming that you are talking about drilling holes in the frame. Is the bracket going to be forward or rearward of the original holes?

well on the HD it uses all of the original holes, so the bracket itself has the compensation built in. Just the holes are spread out more on the HD, so all you have to do is use the forward most 2 on a half ton for reference and then drill new back holes and it will line up ok.
