Ok people (and yes lurkers too)

Here is what I need:

Measurements from wheel center to bottom of the fender flare.

Approximate extra weight (list what you have if you don't know)

Springs used mileage and age on springs if possible as well.

As a side note: I am getting some vibes now in the drivetrain around 55 mph. Roto looks good and so does all else. Do you think that having the trucks nose up a little higher would cause the vibes?

I've almost got my spreadsheet dialed in.
It's getting pretty close predicting lifts based on weight and springs. I would like to include it in the tech section also. How do I do this?

I still need to know the free lengths of stock front and rear springs as well as confirmation of their spring rate 133/210 as well as The free length of the rovertym springs. John?? RonWard??

RTE HD 2" freelengths are something like

Those are the measurements that I wrote down after opening the boxes and puting the tape measure up to them. They sound low, but as they are installed now.....

Hey Keith (Discosaurus),

The OME 764's you have in the front, were they not one of the first generation (For lack of a better description) springs that were actually longer than the current 17" free length 220 Lbs/inch Springs now marketed? Was just curious, as I thought that had come up once before, and that would effect the outcome of this discussion.

I am considering using the current 17" long 764 in the front of my Discovery, because the OME 758 (200 lbs/inch, 17.1") spring is a little short for my 759 rears.

To make this all relevent, my truck is a 1996 SD with ARB bumper and X-9 Winch. I carry about 100 Lbs of gear in the back all of the time, and I run a 10 mm Spring Packer ontop of each Passanger side spring to level.

Front Springs: OME 758 (200lbs/inch, 17.1" Free)
Rear Springs: OME 759 (260-300lbs/inch, 18.1" Free).


Front Driver's side: 20.25" (Hoping OME 764's will bring me up to 20.75" - 21", essentially leveling the truck)
Rear Drivers Side: 21.25"

By Discosaurus (Discosaurus) on Thursday, December 06, 2001 - 02:25 pm: Edit

Yes, you're right.

My 764's were almost an inch longer then the springs OME currently markets as 764's...

Hopefully, we'll be able to get some nice 220 rate springs in 18"+ length from RTE sometime soon !

Keith

By John on Thursday, December 06, 2001 - 02:34 pm: Edit

Why do you consider the rate and free lenghts of springs important as opposed to rate and actual lift? Just curious...

By Discosaurus (Discosaurus) on Thursday, December 06, 2001 - 02:46 pm: Edit

Well, I want 3+ inches of lift but I also want a spring that will stretch the most in a captivated setup for maximum down travel. And, I don't want my fillings falling out on fast whooped dirt due to rigid high rate springs. I'm far from a suspension engineer, but to me that means long and soft springs.

After trying several combos, I've zeroed in on ~220 lb/in straight rates for the front - just like my old OME764's (just longer !).

Now everybody can tell me what I REALLY want...wait, haven't we been here before ??

By John on Thursday, December 06, 2001 - 03:05 pm: Edit

Rate + axle weight + desired lift makes the free lenght fall to whatever it works out to be with wire dia. creating varible free lenghts. Long and soft will will give a stacking problem so the distance between spring mounts also is a player. Thats why I ended up with a 225 main rate front spring that is a dual rate to not stack on the 225 rate, give a 3" lift and stretch as well(25" plus). Its a 20 1/2" long free lenght but a 225/128 varible rate that stacks the 128 rate to give you the 225 ride rate to ride on but not stack under compression...confusing I am sure but it works and is sweet.(SP-2)

By Kyle on Thursday, December 06, 2001 - 03:20 pm: Edit

Makes ya wonder whats gonna happen to that portion with a lighter rate and the point in which it joins the heavier rate over time...


Kyle

By John on Thursday, December 06, 2001 - 03:26 pm: Edit

Like any other progressive rate spring where 2 different winds meet...nothing. The old 759 OME spring is a good example as it is wound under similar construction.

By Discosaurus (Discosaurus) on Thursday, December 06, 2001 - 03:29 pm: Edit

Yeah - guess I forgot about coil stack. Don't want to have those 6" long bump stops that Kyle always rides people about !

So, your truck on SP-2's is about 0.5" lower then my A-version 764's if you discount your spacers. But, they probably stretch a hell of a lot more. Of course, you may weigh more then my setup...

Sounds good - maybe I'll buy a set in the spring before Moab.

Thanks. Now, for the rears. Did you ever have a spring made specifically for those running captivated suspensions ? I know we talked about it during the KKC bulls**t.

By kyle on Thursday, December 06, 2001 - 03:31 pm: Edit

Hmm , not really , the lighter rate is way light. With that light rate its like bending a pepsi can back and forth. Ofcourse that wire and the treating quality plays into it but I am still seeing some pepsi can action there... If they were retained it would be worse....The point in the spring where the rate changes is the point that will see the most stress over time...

Kyle

By Clint on Thursday, December 06, 2001 - 03:36 pm: Edit

John,
I consider the rate and free lengths of springs important because the resultant amount of lift is dependant on the truck's weight. Weights vary greatly. For example, someone with a stock truck who wants a little lift will get too much when he gets springs designed to carry expedition weight.

I would rather calculate the lift rather than hope that my truck is close to the truck that a certain set of springs were designed for. Thats just the engineer in me.

By Clint on Thursday, December 06, 2001 - 03:41 pm: Edit

Chuck just completed the CB lift.
The free length of the stock rears was
left 15 7/16
right 15 5/16
average of 15 3/8 for calculation purposes.

Ron,
These springs are nearly identical to each other unlike the fronts. That is why the lean goes away when you get rid of the stock fronts. I could also guess that the right hand spring is shorter because it was forced to handle more weight to make up for the short front spring, so it sagged a little more.

By John on Thursday, December 06, 2001 - 03:42 pm: Edit

As a progressive rate spring opens it doesnt bend at the progression point by itself, the whole lessor rate spring as a unit begins to unwind its entire lenght as any progressive wind will do.However you look at it is fine.

By kyle on Thursday, December 06, 2001 - 03:48 pm: Edit

Yes , that whole set of lighter wraps will move first but they all hinge on the point that its joined to the heavier rate.That will be exagerated by retaining it. I am looking at durability and longevity... Thats how I am looking at it...Now if its some super high quality pepsi challenge type shit then I am sure its all good....

See it was not that hard

One interesting note I would like to make is that the rear measurement is the same experienced with two DS OME 762s by my buddie Dom when he first did it. So it is a rate choice there.

RTE 225 rate 3 inch springs with one inch spacers in the front.

RTE 285-325 rate 3 inch springs with one inch spacers in the rear.

Springs are only a few weeks old with about 1000 miles on them.

RTE rock sliders, LR wrap around brush bar, about 70 pounds worth of tools in the back, and a full tank of gas.

Driver side front = 22 1/8
Driver side rear = 22 7/8

Passenger side front = 22 9/16
Passenger side rear = 22 3/8

Interesting that most peoples front and rear heights match up where as mine don't. Hmm..

Kyle

By John on Sunday, December 09, 2001 - 03:00 pm: Edit

Put a 5 m/m OME packer under your FD spring. Or 3 1/2" spacers for 26" measurement.

By Eric N (Grnrvr) on Sunday, December 09, 2001 - 03:09 pm: Edit

Maybe, maybe not.. The steering would be the hard part to figure out. If I can keep the drive shafts lined up with the pinion angle it should be OK. The only bad part is the more you rotate the pumpkin up towards the transcase the more the steering suffers. Hell, I may very well still have a slight vibe now. My steering wheel shakes a little at about 50 and I messed around with some things today so hopefully when I go out for a drive in a few minutes I'll know whether or not it is fixed. I wanted to check out the radius arm bushings but, I can't get the f'n arms off and on again with my limited tools and no help. So I may have to get someone else to do that for me. Mine had vibes at two inches and at three, but, they almost totaly went away at four. I think another inch and I should be perfect. Still need to get new tires though. Maybe after x-mass if I can find a set of steel wheels that I like. Hey, where did you get yours from?

By Eric N (Grnrvr) on Sunday, December 09, 2001 - 03:14 pm: Edit

Damn, I don't think that a 3 1/2 inch spacer would look to good. Would have to go for some 7 inch custom springs. And some thing else for a little extra height. Right now though I have other things that I want before I start figuring out how to get that monster truck I always wanted.

Eric N,

PB Blaster, Sockets, breaker bar, hacksaw, factory bottle jack, and a few open/box end wrenches is all you need. You can do it alone. But you don;t need to pull the arm to check the condition of these bushes.
