    Is anyone here running the Hill 4 wheel drive extended shackles? If so have you had any problems with driveablity, off-roading, or pinion angles. I was thinking about using them with my 6" lift to get a little more tire clearance in the front.

    I am not running them, but I was wondering how much extension. I had a friend get some made a local shop for his K10 and it @*^$ed up his pionion angle where he had to clearance grind the yoke, and still a pretty good vibe. He eventually went back down to 3/4" extension and all is well. I know ORD sells set and the lift for 1/2" or so. JFYI.

    I am good friends with Chris Hill, (of Hill 4 Wheel) the maker of these shackels, I can ask him tomorrow if he has had any reported problems or conflicts with what you describe. He will give me an honest answer. From my experience with him and his shop, he is very fair, and runs a straight up shop. He also has done his fair share of serious off-roading, so most likely these have all the bugs worked out....... I'll get back to you.

    Thanks, I hope to get as much info as I can get. I am running a 6" superlift spring w/ a degree shim, so the added length of the shackle will put my pinion angle back close to stock but because of the lift I don't know if it's going to give me a bad vibration. I have already clearanced my driveshaft so binding is not going to be a problem.

    Hey, just went to the web site, and they are only 1" and he talks about already having a shim with lift and the 1" will help with castor. JFYI.

    Check out the product reviews section of CK5. Steve ran them on his rig before he got his D60 in.

    I was looking into them, too, but I still haven't figured out what is wrong with just cutting four pieces of 3/8" steel and drilling two holes in each one. This would be a lot like the stock shackles, which are just stamped steel anyway, except 2" longer, giving 1" of lift. The stock shackle puts the holes 4" apart. My idea was to have 3 holes in it at 4", 5" and 6" of distance (center-to-center). That would let you select stock height, 1/2" lift or 1" lift with just a single part. To change, you would just use a jack and some jack stands, pull out the upper shackle bolt and put it through a different hole. I already have some steel cut and I am planning on trying this out sometime this summer. I am moving from 33's to 35's and will combine it with 1" rear block in the spring pack for an extra 1" of clearance. I currently have no shim in the front, but it shouldn't be a big deal to add one if I need it.

    I am also not sure that the piece welded between the two sides of the HIll shackle has any real advantages. I would almost think it would limit articulation a bit at the limits. Please let me know if anyone knows any drawbacks to my plan. It should cost me less than $20 with new bolts as opposed to the Hill or ORD prices. I'm not sure that I'll have any disadvanteges and the 3 holes should give me the added advantage of being able to adjust the front height to compensate for having the hard top on or off.

    What do you guys think?

    I built my own after breaking 3 of the originals. Basically like the ORD ones, just not as pretty. I made them 4 1/2" ctr. to ctr., make sure you don't leave sharp edges on them to catch the bushings. If your springs are soft enough, you don't even have to jack up the truck, I just use a pry bar against the frame.

    I am running the Hill shackles with my 6" springs. I did have problems with the pinion angle so i just put 4 degree shims between the axle and springs. This fixed any problems that i was having. I will replace the shims that are sandwiched with ones that are bolted to the leaf pack soon. By the way "NOT4SHW" is also running the same shackles with 8" springs and he has no driveablity problems either.

    Hope this helps.

    I stopped by Hill 4 Wheel today and talked to Chris Hill. Told him your concerns, and he said you will not have any problems as long as you are running a 6 degree shim. If you want, call him tomorrow, and let him know you were talking to me about them, and want some more info. Here is his #

    Why would one want these rather than ORD or vise versa (sp?)?

    I'm looking to get the extra 1" to 1-/1/2" of tire clearance that these extened shackles will offer. The Hill shackles are 2" longer than stock and the ORD ones are only 1/2" longer than stock.
