Jeep Cherokee Off Road Mods

rushn12

Hi everyone,

I have recently bought a 1998 Jeep Cherokee Limited 4.0 and am in need of some guidance in what to put in/on it.

I just put a K&N 77 Series High Flow Air Intake and am interested in installing a MagnaFlow Cat Back Exhaust System.

I am completely open to any ideas in ways to make this Jeep better for mudding, rock crawling, and just overall performance. I would first like to do mostly engine work but any expertise you have concerning other areas is greatly appreciated. Also, I am willing to spend the extra dollar to build the best off-roading Jeep around so the best products are preferred.

I can't wait to see what is in store for my new Jeep.

Thanks Guys!

Find a Dual Battery System, and a high amp alternator. The 98 G Cherokee's have a bolt on 130 amp alternator so you can run off road lights at night, other power tools off an inverter, and your winch without running out of juice, or winch across creeks without running the engine.

Then go with 4:10 gears in the differentials so you can turn larger tires, 2" lift = 31" tires, 3" 32, 33 with steering issues in tight turns, 6" long travel is the best for flexing, and they have lower kits, Rubicon Express, for your driveline components which will keep your centre of gravity slightly lower, as well as correct your steering with a pitman drop arm, all included and easy to bolt on for the most part.

A rear locker, selectable or ,,, personal preference, read up, will give you an incredible forward advantage on rocks, and an amazing ability to back out of muck as well. Far less wheelspin when you start off and ....

Front limited slip in the diff over a locker as you still want to turn. Dana 60's are far too much weight for a cherokee to push, unless you are putting a vette 327 under the hood. Stick with dana 44's, much less fabricating and a better brake system too.

Front and rear bumpers, but find a custom fabricator and pay him/her too build you some high clearance ( Approach / departure angle ) bumpers.

Since you have eliminated the stock airbox, pick up another battery plate and an isolator and mount it there for a marine battery setup. If you run in the winter, you will start up much better, faster performance, ready to go winch power, power for inverters, and with the high amp alternator your lights will never dim again when you are winching : ) Then install some bright lights on your roof rack so you can see every animal ahead on the trail.

Thats a good way to spend some serious money, and wheel in a whole new realm of trails and obstacles.

If you still wish to spend more money, then with ARB air locker systems front and rear for lockers... Engine mods, I would do little there, the only company that I would trust with an elec upgrade is, ahh, here look into this stuff, but watch as my 89 is not going to work for all your mods, some you will need for yourself, look further down for a few links.

Hi,I recently picked up a 1994 jeep cherokee sport with the 4 liter inline six.  I took it to have the oil changed about a month ago and shortly there after discovered an oil leak.  After checking it out I found that is was coming from the mount for the oil filter.  The best way to discribe it would be the piece that is bolted to the extrusion molded on the block.  What I need to know is according to the pics that I can find for the motor it is always orinented up and mine is clockedto were thew filter is pionting to the rear of the motor.  I don't know if it was like this before but need to know if there is an o-ring or gasket that sits in there and what the name of it would be so that I can get one a the parts store before I tear into it.  Any help would be helpful.  Thank you

Don't trust that guy for info unless he is a friend of yours, and also a mechanic... Take it to someone who can run a diognostics on it so you don't spend a fortune replacing parts left and right to find the problem. That is what I would do.

I dont know if anyone is still reading this thread i want more performance out of this motor no one is able to help me. I was also wondering if you can upgrade the extras to that of the limited ie,heated seats,adjustable pedals,and my real question quadratrac II with gas the way it is and the fact that I cant afford what i would have to pay for the limited just wanted to know if i could do it piece by piece. Would really like some advice and or help, :confuse:

Hey all I just got a free 98 jeep cherokee sport 4x4 4 door with the classic. 4.0 inline 6. One of the best engines ever. All the jeep needs currently is a full brake job and a front coil spring. I am wanting to make it a nice offroad mud toy. Any and all suggestion would be great. I want to keep it some what a daily driver but i do have a full size ford truck if I do get it stuck. So please tell me what size, shocks, lifts, and tires are know to be the best for these beast. thanks.
