    I'm not sure specifically about studed, but from some experiences and research, so long as ALL the tires on the truck are the same diameter, you won't have a problem running them. If they are the same diameter, then the axles will be spinning at the same rate and it won't interfere with the TOD. Basically any time the speed sensors detect a varying speed of an axle or driveshaft it attempts to equalize them.

    If you go to 265/75R16s your speedometer will read about 7% low.
  • Anyone install tubular side steps on their Trooper?
    I've been checking sources on the web and I am having trouble locating a set for my 2000.
    I'd be interested in hearing the pros and cons, good experiences and bad.
    My wife is only 5 feet tall and she could use a little help getting in and out!

    St. Charles Isuzu.

    Also any 98-01 Trooper application *should* work on a 2000. They are essentially the same vehicles. (heck a 92-01 should also work, except for the front nose cone, everything from the A-pillar back is the same on 92-01)

  • To all Edelbrock IAS Performer shock users and/or OME rear spring users: WARNING:

    My '99 Trooper, currently equiped with OME rear (progressive) springs and IAS Performer shocks all around, just had a rear IAS shock break - literally come apart - while I was driving to work last week. I noticed a terrible noise after I left the freeway and while driving slowly thru parking lots and secondary streets, and on to work.

    This is my 2nd mishap - failure - with Edelbrock IAS Performer shocks. I'm done with 'em.

    Went over to the dealer, and inspection revealed that the IAS rear shock for the Trooper is threaded only about 1/3" (at most!!!) at the bottom of the piston rod which screws into the top of the bottom mounting point. The piston is NOT safety welded!!! Apparently, the IAS for the Trooper is NOT designed for ANY type of lifted situation - even the measley 1-1/2" that the OME results in. Looking closely, the threads didn't appear to be stripped; instead, we think the top of the mounting bracket, over time, began to dis-form enough such that the threaded end of the piston was able to pull out. We unbolted the bottom bracket, screwed the thing back together and remounted the shock. For now it is holding - with very slow driving - my wife is driving to and from the daughters school only. When I remove it for good (in 7-10 days) I will report again with more details of this malfunction.

    This vehicle has NEVER been taken off-road, never driven over drop-offs, never abused, never had the brakes hard locked, or anything - just normal city/freeway/go to work/get groceries type driving.


    I am replacing these "shocks" with OME Nitrochargers (firm variety based on several recommendations) - which is what I should have done in the beginning. Unfortunately, I was taken in by Edelbrocks "slick" marketing campaign. Never again. Please keep in mind that I earlier (last year) had both of the right side (front and rear) IAS shocks develop leaks after going over a moderate bump on the pavement 3 miles from my house. Those were replaced under warranty; bottom line is I don't recommend use of the IAS shock - it doesn't appear to be a truly robust piece of equipment - certainly not one I would trust knowing what I know now.

    About 2 months ago I installed the Isuzu brand black side steps on my 1998 Trooper. They install quite easily, in factory-drilled holes in the frame, although it took me a couple hours because I'm terrible with a wrench. Anybody with some common mechanical sense should be able to do the job in 30-45 minutes.

    I ordered from St. Charles Isuzu, which sells all Isuzu parts at 15% off manufacturer's list price. I believe the price was $279.40. Shipping is free. I think the aluminum side steps were about $330, and the running boards were about $310, IIRC.

    I didn't really look at other brands of side steps or running boards. At $280, I didn't think an aftermarket version would be that much cheaper anyway, and I prefer being able to say/know that it's an Isuzu brand item.

    I decided on the black ones instead of the brushed aluminum because my 98 Trooper doesn't have a ton of chrome/aluminum showing. It's a Performance Package, which means it has monotone paint and body-colored side mirrors (not the chrome mirrors on the '98-99 Luxury Package / 2000-01 Limited trim Troopers).

    So far I've been pretty pleased with the side steps. They look good and feel quite solid-- I bounced my full 185 lbs. up and down on them and there was no flex or sag, although the truck really does rock back and forth!

    I had the running boards on my previous Trooper, a 1996. These were factory-installed. I like the cleaner look of the side steps better, although the running boards may provide more secure footing because of the larger surface area.
  • The shop that lifts the Troopers here in Iceland also modifies the shocks. They weld an extention on to the top. I do not know that much about the process, but it looks fairly easy with the right type of welder. 10k miles and no prblems. Good luck. Troopin.

    Someone on eBay is selling the factory 6-disc in-dash CD changer from a 1999 Rodeo. Just thought I'd mention it. Auction # is 1217355072.

    Don't think anybody has mentioned this yet on the Isuzu Owner's Club...

    A while ago, some discussion on pointed out that a company called Wet Okole makes some pretty cool neoprene seat covers that are customized for many makes and models. A couple Trooper owners had excellent things to say about the quality of the seat covers. They aren't cheap, but if you're looking for a seat cover for whatever reason, you might want to check out In particular, these seat covers seem like a good choice if you do a lot of off-roading or other activities which get your vehicle's interior dirty or wet.

    Paisan, this might be a good link to add to your web site.

    Thanks for re-posting that link.
  • paisanpaisan Posts: 21,181 has the rancho 9000s for $55 currently which is an outstanding price IMHO.

  • paisanpaisan Posts: 21,181
    My buddy who's my Isuzu salesman who also used to be a mechanic, helped me to convert over my XT6 from the stock air-ride suspension to struts and springs. The car handles like a dream now! :) Just in time for Auto-Cross season.

  • I understand that Manik makes a pretty nice set of tubes, that fit nicely with the Trooper. One of their tech support guys told me they are somewhat adjustable in how close you can put them up to the body(range of 2 3/4"-3 1/4"). The catalog pic I saw was pretty sharp. My local 4 wheel parts store quoted me $250 installed. Not a bad deal.
  • Hey Sahara-
    You sure got my attention with your story...I have the exact same setup on my 99 Trooper. Springs were added just last week. I'm going to get it up on a lift tomorrow and have it checked out by my local 4 wheel shop. Pls keep us posted on what you find out. I've been looking for an excuse to get Rancho 9000's or OME's.

    Hey, can anyone tell me what's involved in installing fog lights(Hella) in the cut out locations...they appear to be pre-wired already.
  • cmunizcmuniz Posts: 604
    I had Hella fog lights installed by my local 4x4 shop. They ran a new set of wires from the dash to the lights. They install nicely in the cut-outs, but not as flush as the factory ones. The black trim on the sides and back make them stick out just a hair beyond the bumper. They are very secure and do a tremendous job of lighting back country roads and of course in foggy conditions. I'm very happy with them. I paid $50 for the installation.

    I have the manik tube steps on 2k trooper. I do not like the fact that they only attach in 2 places. Having said that, they hold me up (250+) and look pretty good. They did shift ever so slightly once, but seem to have seated themselves. Other stock steps (other than Isuzu) seem to attach in 4 places. OT...Has anyone tried to install a Nokia cark-91H hands free set? It is the wired one with antennae that uses your cell phone as the "unit". I hope there is enough room. Also, What weight oil is everyone using. So far i am using Mobile One 10w30 and burning a qt about every 3-4k. Next!
  • Yep, that's about my results. Mobil 1 10w-30 and maybe a quart every 3-4k miles. I change just the filter at about 3700-4000 miles, top it off with more oil, and go another 3700-4000 miles before I change everything. Also doing this in my '92 LC that has 135,000+ miles.
  • paisanpaisan Posts: 21,181
    How do you guys change the filter w/o the oil? Doesn't it pour out of where the filter goes when you do that? Just curious.

    I have had the Old Man Emu shocks on since last June, no problems. In early January I put the OME springs on also. The shocks were very beefy compared to the stock shocks. So far so good, even though a couple of ice storms have turned the side streets around here into virtual "off-road" situations...
  • paisanpaisan Posts: 21,181
    I'm thinking of getting the OMEs instead of the rancho 9000s. I've heard great things about both but maybe since I'm getting the OME springs I should stick with their shocks... Where did you order from?

  • We need more folks to make $250 deposit for the Project to begin. Please visit or for detail info. TIA

    Did you get the speaker wire scenario straightened out? Circuit City has both the SONY CDX-4000X (150) and the JVC KDS550 (130) on sale this week + a free set of JBL (low end) speakers.

    Should I replace either front or back with these JBLs (dual cone)? The back definitely sound worse then the fronts. I really don't need anymore highs since those come from the tweeters in the doors and that is mostly what you get from the better 2-way speakers. Do you or anyone know the base response on the stock front and rear speakers (i.e. do the front go below 70 Hz)?

    How does the CDX4000X look in the dash of the trooper. Does the red around the volume knob blend in okay? The JVC has similar features (separate bass, treble, loudness) but less power (40 watts*4) and no readout on the CD titles. The base output on the JVC as compared to the SONY was not as good on the dual cone JBL speakers, but the JVC is a more toned-down looking unit. Also the JVC loads CDs straight-in without opening the front. The SONY could be useful in keeping offroad dust out of the CD player though.

    Any other thoughts?

    Hey Chris Miller, my e-mail has been down today. Check out the page and you can check the prices for the bars. As soon as I get your order I'm gonna process the group buy.


  • I found a site,, that lists an application for the Trooper for $205 plus shipping. $250 installed sounds like a good deal. I think I'll keep shopping.

  • No - how could the oil come out; with the engine off it's all (except a little in the filter) down in the oil pan area. Just unscrew the filter (a little bit comes out like a normal change), put on a new one, clean up the small mess on top of the splash guard (my '99 has), top off with oil to Full and you're ready to go. On my '99 Troop the filter lies sideways. On my '92 LC the filter is actually located higher up the side of the engine, with the threaded part pointed down - makes a nice mess every single time. Oh well, 9 years down and 9 more to go on the LC, then no more messy oil changes!!

    I have ordered the OME shocks from 4 Wheel Parts & Wholesaler guys - the national chain. They are "special" order meaning they don't stock them but instead get them direct from ARB USA. I hope to have them in town in several days.

    Good luck on your decision. If you want to wait several days I'll report on how the OME rides vs. the Edelbrock.
  • Well, I wasted no time after reading enough stuff about Edelbrock....ordered the OME shocks through 4 Wheel Parts. I chose OME over 9000's for two very minor reasons...first, I already have the OME springs and I bought into their "matched for each other story" after talking to Buddy at ARB. Second, I really don't want to have to fool with adjustments(even though it's simple) in the weather during hunting season. It's hard enough just getting my waders and gloves off. I was very impressed with ARB's interest and helpfulness and figure that's a good sign if there's ever a problem.

    By the way, per Buddy's Rx for my vehicle use, I went with softs on front(N26F) and firm(N15) on rear. I'll be putting them on Saturday and posting my "for sale" ad for the IAS's thereafter.

    Hey, I put Hella 450 fogs in my cut outs...a little large, but man are they intense. Now if I can only do something about that flying meteor(bright green) toggle switch that nearly blinds me at night.
  • paisanpaisan Posts: 21,181
    Try using some nail polish on the switch, I've done that on several that were too bright. Thanks for the input on the shocks. I'll likely go with the 9000s or the OME haven't decided yet.

  • bluedevilsbluedevils Posts: 2,554
    Sahara, thanks for the explanation. I am thinking of switching to full synthetic on my 98 Trooper, replacing the filter every 3,000 miles and the oil every 6,000. Currently I'm using synthetic blend - Castrol or Valvoline - and changing oil and filter every 3,000.
  • sdc2sdc2 Posts: 780
    I got my OME stuf at a couple of different places, since I didn't get the springs and shocks at the same time, and at least one of them is out of business. Since then the lowest prices I have heard of are from Tennessee Off-Road.
