Author Topic: Question for all you guys running 63" Chevys (Read 3515 times)

Alright I know there's MANY people out there running 63" Chevys. This is the main reason I went with these springs because I had heard for years how great they were......

MINE SUCK and have absolutely no were NEAR the amount of flex I need, the front with the 44044's are awesome but the back is just ridiculous. So i'm chatting with my friends over at Rock N Roll offroad and they brought something very interesting to my mind and showed me some proven facts that it actually works.

Ok so basically if I were to move my 63" chevys inward more twords the center of the axle and set up the shocks triangled on the outside of the springs this would give it WAY more flex because the farther you go in twords the middle of the axle the less "work" the springs have to do so it'll allow the axle to articulate farther without the spring maxing out so soon. Honestly it seems like these Chevy springs are to thick and my trucks way to light to allow the springs to even begin to bend in either direction.

Wonder what all setup's you guys have tried and what works best, right now i'm on 63" Chevys with 3? or 4 leaf packs and a 3" block with / \ shocks and 8" strait down shackles.

Im considering moving the Chevys inward but that's going to be alot of work. It'll consist of pulling the gas tank out and relocating it along with makeing a cross brace to mount the front of the springs to.

Anyone got any idea's they'd like to share that worked better for them?

TIA,

Shamb

inboarding springs is an old trick that would give the axle more leverage on the srping, but i would mount your shocks striaght up and down to control the springs the best.

Inboard springs and angled shocks would be very "tipsy" for a full body truck. I ran 2 different sets of Chevy springs on my '83. First set was a worn 3 leaf + overload pack. They were very worn and the flex was okay butnot what I was hoping for. My second set was a 2 leaf + overload pack off an '02. They had a great arch, they flexed awesome, and they road great on the street. My shackle angle was probably 45-55 degrees with a 7" shackle
I'd say before you move the spring hangers, check to see if you have a 3 or 4 leaf pack, and also check your shackle angle. That will also affect spring movement if it is too upright.

check your shackle angle. That will also affect spring movement if it is too upright.

That's another problem, they're nearly strait up and down.

Yes, if your angle looks like this, then that's a bad thing.

My truck is the biggest non-flexer there is.

I think the most important thing with chevies is the shackle angle. since the spring are almost flat you can make it really angled. also I think it is best with 3 leaves no overload. That is what I run on my 86 and on my 83 and it works great.

yup,,no over load and good shackle angle..I took the rear clamps off to let the spring come apart and even with out the rear of my truck missing it still flexes pretty good..

taking off or moving the clamp forward help spread the leafs like this..I put on an after market spring clamp.

and here is where my shackle angle is and it works great..

Over all not bad,,,notice the rear axle is straight,,all tires on the ground..

I'm running 3 leaf + overload (Cut at rear of perch, cut 8" in front of perch) and it flexes fine.
I am thinking of removing my bottom leaf and just running 2 leafs to squeeze out another inch or two of flex, but I have very little weight in the back.
Not running bump stops cause the overload keeps the springs from going inverted and my truck is too light to bend them.
I've got the stock clamps front and rear and it doesn't affect flex much.

Just set up your shackles at 45 deg resting and try to keep your shocks verticle.

With Chevy's the more weight you have in the rear, the better they will flex (4Runners get the most flex I've seen yet)

If your rig is too light in the rear, just remove some springs.

Here are mine. 3 leaf with double shackle. The rear shackle mounts moved forward 2 inches for better shackle angle. I made my own shackles 9-10 inches long. Shackle angle is great. You can see that they flex pretty good. A lot of the flex is cuzz fo the double shackle pulling down. It rides great on the road and i haven't gottem them to unload on me when it was a DD. I don't drive it on the road anymore.

Ramrod · « **Reply #10 on:** Aug 29, 2005, 09:12:36 PM »

You don't drive it on the road any more at all? I love driving my truck on the street. I get so many looks and thumbs up, especially when I put on my flashing blue led rock lights

MiniSimp · « **Reply #11 on:** Aug 29, 2005, 09:35:46 PM »

Hyena, your flex sucks, you should be ashamed!

mr4x42u · « **Reply #12 on:** Aug 29, 2005, 11:31:34 PM »

minisimp,,,your spring still won't go negitive with the over load out..I have not been running on overload basicly after my 1st trip out with these springs and they have yet to go past flat..I say don't run an over load..these springs will be fine even with two leafs and no over load..

Hyena · « **Reply #13 on:** Aug 30, 2005, 03:37:10 PM »

I drive it on the road when i have too. I had to drive it and hour and a half home From Hell Hole a couple weeks ago. It was hella fun bombing down the road and it didn't have any vibrations at all. but i would still rather trailor it to the trail and have to worry about breaking it and calling a tow truck again.

hmm.. yea i hear alot of "its all about shackle angle, shackle angle, shackle angle"

maybe i'll experiment tomorrow for the heck of it...

i'll cut my shackles and just move the "mounting point" on the frame forward a few inchs to make them at more of an angle.

See if that helps.. if it doesn't someone's gonna be pulling me back on all 4's when we get to MCR4 cuz i'll probably roll that bi-atch multiple times

btw that picture in my Avatar is me flexin on my buddies Runner with 39.5" Iroks and I was about 1/2" from flopping it, literally you could have walked up and flopped it over with your pinky...

I thnk if you mount the rear shackle mount about a 1/4 inch behind the stock one your angle will be perfect..

Shamb · « **Reply #17 on:** Aug 30, 2005, 10:45:02 PM »

in other words.. 1/4" back from strait up and down?

there's no more "stock" position for me.. i've chopped the frame back.. lol

mr4x42u · « **Reply #18 on:** Aug 30, 2005, 10:50:33 PM »

if you put your axle in the stock location then mount the shackle mount 1/4 in behind the stock shackle mount..

I can put an angle finder on mine and see where it sits if you want..I just kind of eyeballed mine where I thought looked good..so far been happy,,even with out all the weight I lost by hacking the back off..

Shamb · « **Reply #19 on:** Aug 31, 2005, 09:53:25 AM »

nah thats okay, i'll just go off of the pictures provided here and mount mine the same.
