1982 1st Gen Pickup
4" procomp suspension lift consisits of 4" lift springs on front and block lift in rear
now sagging to little over 3" now.
1" RB body-lift
front axle widened using IFS hubs axle now 58"
rear axle widened with 1.25" wheel spacers now 58"
35x12.50 BFG MT KM tires on 15x8 3.5" backspaced wheels.

Front tires do rub under full compression even with 1" body-lift


Currently running rancho 5012's on the back like this / \.

I don't recommend the Procomp suspension lift it came with my truck but I wouldn't buy it personally.

The plan for my suspension is going to 63" chevy springs on back and rear springs on the front.
Info on 63" Chevy springs:
63" Chevy springs FAQ
I will be using Bud Built chevy spring hangers and a custom built rear shackle out of 3/8" 2" wide flatbar it will likely be about 7-8" long.

Here's a little info on the rear springs on front subject
Rear springs on front FAQ
A side not on rear springs on front you basically have to build your own pack and experiment to get the right combo you want.
I will be using a combo of leaf springs from a 85 2wd rear pack and my old 83 rear spring pack.
This will also address rubbing issues with the front wheel well since it moves the axle forward at least 1-1.5"
Also you cannot use the stock push pull steering with these either.
You must goto a hysteer setup.

Then I am adding the Ford F350 shock mounts and rancho 5012's to front as well.

Prices:

4" Procomp suspension lift - $513.99

Planned suspension going on:
Bud Built chevy spring hangers - $55
4ea Rancho 5000 5012 shocks - $160
RB 1" Body-Lift - $90
Junkyard not rusty good condition 2000 63 Chevy leaf springs - $120
U-bolt Flip kit for rear - $55
Budbuilt 8" shackles $40

Ford F-350 shock towers - $30
used 85 2wd leaf packs $40
Rear stock leaf pack - free
Budbuilt Banana Shackles for front springs $50

Sky-Manufacturing Hysteer - $413
IFS steering box - Got for free

Other stuff

4 ea 35x12.50 BFG MT KM tires $760
4 ea 15x8 Rock Crawler series 51 3.5" backspaced rims - $200
2 ea 1.25" wheel spacers - $110

Probably about $200-$300 in welding required for the spring hangers and shock mounts and mounting IFS box.

Funny thing is I put that all togehter back in 2002. It is horribly out of date and we have found so much better stuff these days.

I actually "LIKE" the 2" ID Sway-A-Way's at that point which are complete garbage. Biggest waste of $700, bar none.

Old Man Emu Coil/ Shock Info

ok, this may be a long post, but i got some information a while back on all the OME gear for a 3rd gen 4runner. the following is a long email train about it. some things ARB told me conflicted with what i had previously thought so, you may find it intersting. read it from the bottom up.

Well, i'm corrected on the 906's. They are still being made. I just talked
to the tech guys about it. The 906's are a heavier spring rate at about
220lbs. They are not as tall as the 890's.

Trim spacers in that truck can only be used for levelling out the truck left
to right, not front to back. They're 5mm each for the front and i'd say you
couldn't use more than 2. The rears are 10mm.

Biggest problem is the IFS and the shaft angles if you get too much lift.
Leads to bigger problems.

So if the 906's aren't being made any more it sounds like they wouldn't be
an option for me. If I went with the 890's in the back, you guys sell trim
packers to raise the front, correct? What size are they, and how many can
be used on the same spring safely? Thanks for the contact info in San
Diego.

I believe the 906's aren't being made anymore. I don't have a reason for no
info on it, it just skips in my guide. I believe it's the same thing as a
stock spring.

Between the 880 and 881, yes, just length. You'd use a heavier shock to
allow for more weight.

By using the N91SC and 881 on a stock front end would be a little firmer
because of having a little more spring stuffed in there. To get the most
comfort, use the 880's on the front with the N91SC.

For the rear, it may sit a little higher than desired (compared to the front
end) if you go with the 890's and softer shocks. I can't see that it would
give you a problem, but it's not listed to work with it like you mentioned.
You'll always wanna pair up the springs and shocks as listed for the better
ride.

In San Diego, you can talk to Pro Gear at 858-571-1158 or Off-Road
Warehouse at 858-565-7792. Each of those 2 dealers of ours both sell and
install all of our products, including the OME gear.

Subject: RE: suspension questions


Wow, thanks for the quick response.

Currently the vehicle is stock, with the factory tow package and roof rack.
I really don't tow much (or at all), and I don't foresee adding anything new
such as a front bumper, winch, rear bumper, roof rack or tire carrier.

The info I had below on the spring numbers comes from various vendors
online, such as wheelers offroad, 4x4 connection, and xtremeoff-road. Looks
like they may have some incorrect information.

I have never heard or seen anything about a 906 coil spring, or of anyone
using one. Is there a reason you don't have information on it? Is it
basically similar to the 89x springs? If so, I would think its longer and
narrower then the 890 but has a lower spring rate?

It looks like the only difference between the 880 and 881 is the length, or
consequentially the lift. Would there be any adverse effects to using the
881 spring with the N91SC shock with a totally stock front end? For the
rear, would there be any problems with the 890 springs and the N86C shock?

Also, I have found a few dealers online, but none in my immediate area. I
live in San Diego, CA 92107. Could you recommend a dealer down here that
would have OME gear? Thanks a lot for your help.

Subject: suspension questions

Hi Brian,

What we have listed is almost the same as what you have listed to me, but
with one change. The 880's and 881's are for the front (light and heavy),
and the 906's, 890's and 891's are for the rear.

We'd be looking for a little more info from your end about what kind of
accessories you have or plan on getting for your vehicle. Bull bar, winch,
rear bumper, spare tire carrier, roof rack/cage, roll cage. These add up to
necessitate using a heavier spring set.

I'll just run thru the options that we list (that you've already seen) then
go thru the details of them each.

For the front.
Stock/light load (0-110lbs)
1.25" lift. Spring OME880 , shock N91SC
Heavy load (110-240lbs)
1.25" lift Spring OME881, shock N91SC or N91S for firmer ride

Rear
medium load
2" lift spring OME 906, shock N86C or N86 for firmer ride
Heavy load
2.75" lift OME890, shock N86
Heavy constant load (660lbs to GVW)
3.0" lift, OME891, shock N86

So the different lift for the back is when the car is not loaded, but once
the weight is put in, it'll rest closer to the 2" level.

Now for the tech info. Listed in order of diameter mm's, length mm's, #
coils, weight kg's, spring rate lbf/in.
880, 16, 365, 10.2, 4.7, 500
881, 16, 375, 10.2, 4.7, 500
906, no info here
890, 15, 435, 10.2, 5.7, 190
891, 16, 420, 10, 6.4, 210
892, 18, 400, 10, 8.1, 380

You can see the 892 is just not suitable for this. It would fit, but you'd
have fun getting it to do anything...

Shocks on the front are same length, different valving.
Shocks on the rear are the same length, except there is a softer shock
listed there (N86C) for medium use.

These springs are not progressive, although some for other model vehicles
are.

If you're not planning on rigging this thing out with any heavy stuff, then
you'll get a great ride, with a little lift, but capable of handling all
sorts of terrain.

Let me know any questions you still have, or if you need the name of a
dealer in your area.


Thanks,
Michael Tomczyk

Subject: OME Inquiry from ARB Web

Hi,

I have a few questions about your Old Man Emu suspension products. I have a
stock 2002 Toyota 4Runner SR5 4x4, and want to upgrade my suspension with
your products; I've heard nothing but good things about them. I'm looking at
your 880, 881, or 882 springs for the front and your 890, 891, or 892
springs for the rear. I can't find any statistics on these springs on the
internet. I got a copy of your literature delivered to me, but again there
are no specifics. What I would like to know for each spring is: the spring
diameter, the length, the spring rate, whether or not the spring is
progressive, and the anticipated lift vs. the stock spring. Also, for your
shocks, is there any difference in length between the firm valved and
comfort valved shocks? Right now I'm thinking of using comfort valved shocks
no matter which springs I get, if that is possible. Any other advice you
have would be appreciated as well. Thanks a lot for your help.

Interesting thread! I run a pretty cheap setup.

Front
- Revtek top out spacer
- Cornfed 1.5" coil spacer
- stock front coils
- OME firm shocks
= about 2" of lift

Rear
- Stock coils
- Cornfed 2.5" spacer
- OME firm shocks
= 2.5" lift

Here's some pics:

Interesting thread! I run a pretty cheap setup.

Front
- OME 882 Coils
- OME Firm shocks
- ATS A-arms
- Revtek Diff Drop Kit
= about 3.5" of lift but has sagged to 2.75-3"

Rear
- OME 891 coils
- OME Firm shocks
- OME 5mm trim packers
= about 4+" or lift, but with a roof rack, bumper and stereo it's now at 3.5"

Tires - 285/75R16's

I've since added a Roger Brown 2"BL and have 35's now. I plan on swapping out the trim packers for either OME 892 coils or just add some cornfed spacers

97 Tacoma

OME 880 Coils up front (approx 1" lift)
OME "firm" N91s struts
Deaver 3 Leaf Progressive AAL (approx 1.5" lift)
OME N85 rear shocks

With about 1" of lift I am running 32x11.5 Dunlop MTRs and they fit great, with just a little rubbing on the mud flap @ full lock or while hitting bumps and turning. Now, I know most people say to run 2" of lift to fit 32s but I didnt want to put the stress on the CVs and front IFS etc so I ended up going with the OME 880s instead of the 881s or 882s. I think the TJM up front helps with clearance issues with so little lift....I have not wheeled the truck yet with this setup - but I have a good amount of clearance overall.

edit: removed the mud flaps minimized rubbing issues. Small amount of rubbing when suspension is compressed and truck is in reverse, also some rubbing during hard hits on the front ifs while turning. Nothing too bad. Removing the mud flaps really makes the truck get alot dirtier - espescially up here in NH - road salt is EVERYWHERE and the truck is constantly covered in it.

With the 32s (up from 31s) I have lost about 3 MPGs or so. Previosuly I got between 300 and 315 per 16 gallon tank. Now I am getting about 250 miles per tank. About 18-18.5 mpg previously - now I am averaging around 16MPG.

I run the TRD OEM Tundra/LC setup, I purchased the "kit" from Steve at Sonoran Steel for the ease of not tracking down everything myself. it included the panhard drop bar, longer rear brake line, lswaybar mounts, bumpstops, diff drop, all the shocks and springs and one spacer for each side in the front. and im probobly forgetting something else too.
I have Lexus GX470 rims, 265/70r17 tires and 1.5" bolt on wheel spacers. I also have 1 spacer ontop of the front shocks.

Donahoe racing 3" lift extended travel coilovers, flex like a champ with swaybar off, take ANY amount of air or abuse smoothly without damage or bottoming out, fully rebuildable. As for the back, im ordering a 1.5 inch lift AAL to increase load capacity and height a little, and to get the blocks out, then im also going to do 1.5" longer greasable shackle hangers to give me more flex and compensate for the small amount sacrificed by the AAL.

i am utilizing a revtek 3" suspension lift that gave me an additional .5" of lift in the front. Really helped on trails. I reneged on the diff drop. It's not necessary. I have wheeled the crap out of my tacoma with absolutely no ill effects. The revtek is complimented by a 3" bodylift which has been great for improving approach and departure angles.
