Very Basic Zero rate question

    Here's a basic noob question about how zero rates work. Here is a pic of my zero rate on my 4" lift springs I bought. They are currently set up to move the axle foward. How do I set them up to move it to the stock location and simply use the zero rates for lift, not relocation?

    [​IMG]

    Will I have to remove that little metal nipple that sticks down in the center? Or do I use the other bolt hole on the right? Or do I just loosen the center pin and spin the zero rate around?

    I'm missing something basic about how zero rates work.

    thanks for the help,
    James

    Get a new center pin and place it where the "little nipple" is.
    When you take it apart to change it, it will become painfully obvious

    basically flip them over and run a center pin in the middle hole.

    no you cant. the center pin would be recesed in the hole. just do like abouve 2 new center pins and run them stright up threw so the round nub is sticking out like now but no off set bolt threw the spring pack.

    true, I was looking at wrong hole. Just get a longer center pin and run through middle hole. I take a grade 8 bolt and round the hex head round and use as a center pin

    so let me get this straight, I knock out the nipples, buy new center pins of the correct length, put them where the nipple was, and call it good? Use C clamps to hold the leaves together when I do all this, right?

    If anyone knows a part number for the new center pins I would need, that would be awsome.:bow:

    You can use a 3/8" fine-threaded grade 8 bolt of appropriate length and just grind the head round. Your local spring shop would prolly also have the center pins -- they come in various lengths, so there's no one part/number that fits all -- but I find that they're easy to make.

    Stick the bolt into your drill, and bzzt it up against your bench grinder, or pin a pinch, an angle grinder (maybe your buddy holds it?) and voila, poor man's lathe. Only takes a minute to round the head off ... first time you'll INTENTIONALLY round the head off a bolt, right? :D

    I have a quick question too if it's alright to jump in here James...but I was wondering if the zero rates will work okay with a 4" lift block? I haven't invested in a shackle flip yet.

    Thanks

    So what I round the head off and eventually want to take the spring pack apart?

    I have no local spring shops. Do auto parts stores carry center pins? I'm almost thinking about taking the zero rates off the springs, but I would STILL need new center pins, right?

    If you want to take the spring pack apart, just use vice grips:D

    If you insist on "buying" new center pins instead of making your own, call ord, they have them.

    The center nipple in your pic is just a short center bolt, you just un-bolt it once the zero-rate is off and replace it with the new center pin going through the leafs.

    Cool, that's what I was kinda thinking.

    I'm wondering if ORD will sell me some of the full length center pins that come with the new zero rates they sell? I guess these would be the correct length for 4" RC's and zero rates?

    Does anyone have some center pins they're not using laying around? Either some that will work with zero rates, or maybe even just some that came stock in 4" lift springs? I may take the zero rates out before its over, still don't know.

    thanks,
    James

    As somebody else said, you can install/remove them with vise grips. You're really worrying too much -- coupla bucks for bolts at the hardware store and you're good.

    If you get some that are too long, just cut off whats hitting the spring plate AFTER they are bolted up.

    So is that a grade 8 center pin, or a bolt that you rounded the head on?

    So does the round part of a center pin go on the bottom on the spring, or top of the spring?

    I've found that using allen bolts of the proper length work perfect as the head is already round and of the correct diameter and they're grade 8 too.

    The round part goes down, there's a hole in the perch on the axle for it to fit into.
