I changed different coils and coil spacers on 3 different late-generation Isuzu vehicles, totally probably more than 10 times. Now as I used to this procedure, it takes only 30 minutes for me. I am using a different sequence of actions:

1) Disconnect the rear sway bar, if you have one. I am not using the rear sway bar on my vehicles. I am always removing it. With better shocks and coils, you do not need it, really.

2) Disconnect the brake lines, if you do not have the brake line extension.

3) Disconnect the upper shocks mounts.

4) Take the Hi-Lift and raise the passenger rear side of the vehicle ( I use the rock sliders as the jack point).

5) Replace the right coil.

6) Lower the passenger rear side of the vehicle.

7) Reconnect the passenger rear shock.

8] Disconnect the rear bolt of the upper driver side trailing link. If you are doing this first time on your vehicle, and you are not a guy of strong build, you may need an impact wrench.

9) Take the Hi-Jack and raise the rear driver side of the vehicle.

10) Replace the coil.

11) Lower the vehicle.

12) Reconnect the trailing arm. If the holes do not fit, jack the axle under the link with the stock bottle jack until the holes more-or-less fit. Force the bolt into the hole with the rubber hammer. Tighten the bolt and nut with your hands. Do not use the impact wrench here.

13) Reconnect the driver side rear shock.

14) Reconnect the brake lines if you disconnected them.

15) Reconnect the sway bar if you have one.

The actions 3 through 13 take about 30 minutes; I have all the convenient tools for that. I do not need to do the actions 1,2,14,15, they would add another 15 minutes, I guess.

Hurray for special tools! LOL



A port-a-power makes moving the axle back into position to line up the upper link soooo much easier. A bottle jack and piece of 2x4 will also work well, just takes more hands.

Ok Probably a stupid question.

Is their any store that sells "new" trooper springs that anyone is aware of?
Looking for something like Autozone not online if possible. Tried all Autozone , Oriley , and Napa couldn't think of any others.

I tried playing in the Mud last night and actually sheared my stock spring in 1/4. Will try to get pics.
Checked my local salvage yards and struck out at 5 different ones.

Unfortunately this is also my daily driver so this wasn't very bright of me...

I put 31x10.5 on my truck and they fit without rubbing , but I have a feeling it will be another case with my 22' boat on the back. And I would like to hang out with my Mudding buddies on occasion. Any help is greatly appreciated.

you can buy OME 912 springs from Indy4x. They will give you almost stock height for Trooper (may be 1" more) and better than stock ride.

Just a quick note. Should have mentioned, this is for a 99 Isuzu Rodeo 2 wheel drive 6cylinder 3.2.

Was considering this for a 2" lift before I broke a spring. Or is their a better more ideal way of doing this? All suggestions are greatly appreciated.

OME912 will give you 1.5" or 2" lift for your Rodeo.

OME913 would give you around 0.5" - 1" lift.

This is comparing to a vehicle with the new stock coils. If you compare it to a vehicle with some old sagged stock coils, you will see higher lift.

This is the magical answer to my question - You are Da Man much appreciated sir!

Actually OME 913's will give you a 2" lift, and OME 912's will give you a 3" lift. I have put 913's on my Rodeo that only had 50k miles and wasn't sagging at all, and got a full 2" of lift. Others have measured their 912's and got right at 3" of lift.

This is not what I observed on my 2002 Rodeo. On the new Rodeo, 913s gave me almost no lift. 912s, together with 2" spacers, gave me 4" of lift (4-2=2).

The same figures I got on the Axiom, so this is a consistent situation. Now I am using 929s (much stiffer and larger coils than 912s), and those are giving me just 3" of lift without spacers. No way 912s can give the same amount of lift as 929s.

I'm curious if their would be a difference between 2wheel and 4wheel drives. I know the chassis are the same but the weight distribution and shock ( aftermarket or stock ) make a difference maybe?

Haven't decided on exactly what to buy yet. Still considering some used shocks. absolute height is not critical. I was hoping to get at least 2" but no more than 4". I'd be happy with under 3" just so I dont have to change the shocks and extend the brake line to be honest.

That's strange Holger. I'm not saying your wrong or anything, but many people here have gotten a 2" lift with 913's (like myself) and a 3" lift with 912's. Gizmo has put 912's on 3 different Rodeos and got a 3" lift out of all of them.

I don't think it really makes a difference with how much coils will lift the rear rather its 4x2 or 4x4. Yeah if you're not wanting to deal with the shocks and such right now just get the 913's for the 2" lift. Like me you can just add spacers later on if you want some more lift.

I do not know what to say. Did you take into account the new larger tires ? Did you measure the lift immediately after the lifting, or did you give it time to settle (a month may be) ?

After few months the OME settle back at least 1". All OMEs that I personally tried on 2 vehicles (913, 912, 919, 929) did just that. So, to get a permanent lift of 1.5" - 2" you need the initial lift of 3". This is 912s.

OME lists in their catalog that 913s provide just .75" of lift for the Rodeo. You can check it on their site. And this is consistent with my results on 2 different vehicles. To say that OME is so way off about their own products... provided I double-checked it myself, independently... it would be a bit of stretch.

Actually I installed the 913 coils with the stock rims/tires the measured and it was right at 2". Then I installed 30" tires after that and it gave me about another 1/2". I also measured them about a month later (since I waited a bit to get an alignment, and I wanted to make sure the t-bars were cranked about an inch under the height of the rear to give it some rake) and they settled maybe 1/8th of inch. I also re-measured about 3 months after that before installing my spacers and 32" tires and they were still at the exact same height.

I completely see where your coming from, but the fact is multiple (not just a couple) people have gotten the same results of 2" with 913's and 3" with 912's. Not much else can be said about it.

It does not matter, they will work the same way.

If money is not an issue, and you do not need really long shocks for off-road, then take OME shocks application for Rodeo. They are a little bit longer than "stock height" shocks (OME shocks extend more than other shocks with the same length) and they are good through the whole suspension travel on a lightly lifted vehicle.

If money is the issue, then just take some Monroe or KYB, both are cheap.

Used shocks are not a good idea.

did you check the height after a month or two ?

Edited my post above with the answer to this question.

This is strange and not typical. Many people complained here about too much settle in OME. And I observed this set back myself. But... "your results may vary".

By the way, 50K miles is still a mileage. And there were several years of permanent pressure on the coils by the vehicle weight. You cannot say that "it wasn't sagging at all". You just did not see that it was sagging - a little, an 1", for example.

I observed how my former OME 919s sagged (initially) 1" after 1 (just one) trip of about 1000 miles (including some 'wheeling). Before the trip, I could not fit my vehicle in the garage; after the trip, it was fitting perfectly with some extra clearance.

The 913s and the stock coils are much smaller than 919s.
