1991 Jeep Comanche Eliminator 4.0 from North America


Fast, reliable and sporty


To date I have done very little to this truck except general maintenance. This is my second Comanche. I drove over 400 miles to buy this truck, that's how much I like these trucks.

General Comments:

This is a super fast little truck.

It's a shame Chrysler discontinued this truck. I get comments on it everywhere I go, it's a real headturner.

Would you buy another car from this manufacturer? Yes

I too have a Jeep Comanche. 1990 Eliminator 4.0L L6 motor putting out about 350 horses, with a AX15 5 speed transmission.

I love this truck!!! I have done all the work myself and have bought the Comanche new in December 1989.

The truck now has 245000 miles on the body and frame. The motor has about 35000 miles on it now. I get about 10 miles to the gallon, but I get where I'm going quick.

More Power, that's what it's all about. Engine mods: Stroker Kit from Hesco, Cam from Comp Cams, 60 thous over on the pistons, Ported Polished aluminum Head with roller rockers from Hesco, Bored and ported Throttle body from Hesco. Ported and polished Intake manifold, Headers with 3" exhaust all the way back (Stainless). Dana 44 with 4 11 Positive Track Rear, Dana 35 with Positive Track Front. Cold air intake from Hesco, High flow Thermostat Housing, High flow water pump. AGR Steering Box. All Plastic Vacuum Lines have been replaced with 1/4" Stainless Lines. And Many more Mods.


Thanks for listening


1991 Jeep Comanche Pioneer 4.0 Litre from North America


Fast, reliable, and rare, there's only one


The front brakes needed to be replaced when I first owned it, I did that, then 4 months later, the callipers went out, causing me to redo the entire front brakes.

The oil was leaking from the rear seal ever since I purchased it.

There is piston ring blowby, I don't know when that started, but I found it out this summer.

Right now, the back brakes are worn to hell, and are hanging up.

General Comments:

The specs: 1991, maroon, long bed, Pioneer package, 4X2, auto, 4.0L, CD, air, rear-sliding window, 185HP, 225 ft lbs. torque?

The only reason I bought this truck was because my friend owned one, his was a 1990, short bed, 4.0L manual, sport package. When he let me drive it, I fell in love with the truck. I was sick of driving my 1984 Toyota Corolla around, so I had to have a Comanche.

I really wanted a manual, but auto is fine, not as much performance though.

I do have air conditioning which is great for the summers around here.

I would recommend this truck to anyone, it's just a fun truck to drive. And very fast, lots of low-end torque. I really would have liked to find a 4X4 version.

My first winter with it was last year, and it got to 10 below zero (F), she started right up, absolutely no problem. The heater works GREAT, I stress great.

After 103,000 everything is original, except tires, brakes, battery, exhaust and CD. The only thing that irritates me is that Jeep has heads where they're not supposed to be.

They should put them back into production, I know at least 10 people who whould buy one brand new.

Another thing, I think the highest concentration of Comanches is in Kenosha, WI, I have counted 32 different Comanches!

Yes, I would buy a new one, I have a short bed 88 with 4.0, auto, air, PB, PS and disc player.

You might want to check the valve cover for a leak. I had a leak that I thought was the back main. I took it to a dealer and had it replaced. When I got home with the truck it still had a leak. I replaced the valve cover gasket and stopped it. It was leaking on the very back of the cover.

I now have 213,000 miles and still runs strong with no oil consumption.
