    Sorry for being so clueless, but what is the difference between a Hi-Pinion D60 and a regular D60 ??? Any advantages or disadvantages.

    The difference is that the complete pumpkin is flipped upside down,to reduce pinion agle,up to 3-4 inches(mabey more) /forums/images/graemlins/thinking.gifallowing more lift,with less of a drastic angle on the drivelines.or driveline.The shaft is now coming from the TOP of the pumkin,instead of below......... /forums/images/graemlins/thinking.gif /forums/images/graemlins/thumb.gif

    Dynatrac was cutom making a "reverse cut gear" for use in their HP diff when in the rear. I don't know if they still do though. Some guys have talked about using ford front gears (reverse cut) in a HP rear end also. I just drag my axle so what do I know
    (My name is matt and I am a 14FF owner) <- intro at a 14FF intervantion.

    Jake, why all the excitement for high pinion axles? I noticed you are running 38" tires. Makes me wanna ask how much lift are you running? The GM D60's are more than adequate for the job of turning 38's, and even much larger tires, with even taller lifts, too. You're not going to find any type of 14FF thats a HP. Only the Ford D44 and D60 front axles are HP's and the aftermarket selections are the same plus Currie's whom offer a HP 9" rearend.

    A true HP Ford front does not give 3" to 4", or maybe more, of a higher pinion. From a standard D60 to the reverse rotation D60, there is only 2 1/4" difference between them.
    The standard 60 pinion centerline is 1 1/8" below the axleshaft centerline.
    The reverse 60 pinion centerline is 1 1/8" above the axleshaft centerline.

    The 9" Ford rear pinion centerline is 2 3/8" below the axleshaft centerline.
    I don't know how much above the line the Currie HP 9" is.

    So, if you have a mild lift, I would just stick with the GM D60 so you can keep the transfercase all GM by retaining the passenger side driveshaft. If you switch to a Ford, you will need a Ford transfercase.

    Tell us more about your lift and how much you are running. /forums/images/graemlins/deal.gif

    A high-pinion used in the rear has the same strength disadvantage as a low-pinion in the front. I'm not aware of any high-pinion designs that would not run on the coast side of the gear in a rear application. (If there is, please share /forums/images/graemlins/bow.gif )

    Thanks guys....yeah,ill probobly end up just running a 14 bolt there in back w/detroit,just curious,thats all.To answer your question about how much lift i will run,it will be an 8 bds lift up front ,and a 4 on the flip with 6 springs.zeros up front.I wanted to see if there was an "affordable" way to get a rear h/p,without paying the toll /forums/images/graemlins/deal.giflike i did on the front....wich was overkill in the firstplace.Ive heard the tera pumpkin has had some oiling problems in the past.Its too late on the front h/p,ive already bought it....lol id have been done long before with the thing if i went with a regular d60 /forums/images/graemlins/rotfl.gif SO.......Steven Watson is the only other guy you guys know of that is running an h/p?That you know of on here?Id like to touch base with some more h/p freaks like myself...so post up.if your out there.....Jake /forums/images/graemlins/thumb.gif

    thatK30guy!

    You seems to know very much about the vertical hypoid-offset, Gm 10-bolt or ford 8in?
    I am looking for a ring-pinion with 1.75in hypoid-offset.
    (low pinion rear).

    I don't have any info regarding the 10 bolt or 8.8" rears. I'm called K30guy for a reason. /forums/images/graemlins/waytogo.gif /forums/images/graemlins/thinking.gif

    But if you are dead set on trying to find a rear with a lower pinion offset, the 9" Ford is probably the lowest on any production axle. I've yet to see anything lower than that.

    old cadillac axle.

    Watson is the "bling factor man." He can run whatever he wants because he can afford it. /forums/images/graemlins/waytogo.gif

    6 springs.zeros up front

    [/ QUOTE ]

    Thats what I've got in the works for a future buildup. I've got 6" Skyjacker springs laying in the garage and also got some zero-rates made with 4 degrees of taper milled into them to tilt the pinion angle up slightly. I also got some of TONYP's custom made u-bolt plates also milled at 4 degrees to help seat the u-bolt nuts squarely so they don't suffer from stress and break later. Stock u-bolt plates will not suffice as they can seat the nuts at an awkward angle when the nuts get torqued down. Using a matching plate to the zero-rates will allow the nuts to seat 90 degrees and have NO stress on the u-bolts.

    If the above info sounds confusing, let me know and I will find my thread have saved about the D60 and the problems with shimming them. /forums/images/graemlins/waytogo.gif

    I'm gonna run all the items I listed above on a standard GM D60 and should not experience any problems. Kind of like doing some homework here, asking the right questions (like you are doing now), and getting the right parts, both off the shelf and custom made. Thats one of the best things about this site when you have contact with some of the best machinists whom can take in consideration your ideas and put them into reality. I cannot even name off all the awesome guys who do stuff like this. /forums/images/graemlins/peace.gif

    /forums/images/graemlins/thinking.gif Hmmmmmmm...interesting. I'm gonna suggest that question could be better replied if you were to ask some more wide based knowledge guys over on the Pirate 4x4 site. They've got a crapload of guys who drive literally anything and everything. And with guys like that, there will be more answers to your question like that. Afterall, CK5 is generally all about GM's. /forums/images/graemlins/waytogo.gif
