Spring Rates?

Ok, I’m new to “newer” Jeeps. I have a 97 TJ with 31X10.50 Firestone Destinations. My past Jeeps were all from the 1950’s and 60’s, and I have a quick question that might sound stupid to some of you.

Why do suspension manufacturers list two different lift kits…one for a 4 cylinder 97 TJ, and another for a 6 cylinder 97 TJ? I am assuming the only difference is the weight of the vehicle? Is this correct or did jeep decide to make something a millimeter smaller on 4 cylinder vehicles?

I haven’t had the 97 for even a week as of today, so the only mods so far are the above-mentioned wheels and tires, and an abbreviated rock bumper that I just built. Still to come is the rear bumper/carrier, complete undercarriage skid plates, front and rear lockers. The rest will be run of the mill Jeep upgrades, so I will not bore you with all that.

I am a structural steel fabricator/welder by trade so yes I will be building all my own components. If I can build bridges, modify and repair naval vessels, heavy equipment, and fabricate for government contracts…there is no way I am paying $400 for a bumper I can build myself (to a higher standard), in one Saturday afternoon.

PS…if anyone needs a component built, let me know. I guarantee it will be better in every aspect and a hell of a lot cheaper!

To answer your question, yes. The 4 banger is lighter than the sweet I6. One thing to look at as well is Old Man Emu suspension has light and heavy springs depending on if you have a winch or a heavy rear tire carrier.

Honey, I'll have to buy a winch to balance out the weight of the rear tire carrier...
