Tires, gears, lift please explain

Without staring any holy wars.... I've been poking around on mods. It seems folks like to add LIFT to their YJ. They like to add bigger tires. Change the rear pumpkin gears to 4.10s....OK in simple plain talk, WHY ? I'd like to know what the basic benefits are to the those 3 mods ? I get that Bigger tires looks COOL. Are they actually useful to either off road or economy ? Same question for the gear and lift alterations. I'd just like to know what all the hubbub is all about.

looks and performance , for most it's for looks , a stock YJ is great off road , a little lift and tires take it a little further , gears and lockers even further , it kind of snow balls from there , as far as economy , I didn't buy mine for the stelar gas mileage , I did it because chicks dig JEEPS !!!

Here are some other ideas. Biggger tires are wider and in my life it makes the Jeep more stable on the road. Lift helps with clearance when offroad, looks cooler, allows the bigger tires to fit, and if you go off road keeps the tires from hitting the fenders when articulating.

You also sit up higher and can better see the traffic ahead of you as you drive. The lower gears are needed to keep the overall power and quickness the same as you install larger tires. It can also help keep your gas mileage the same. If you have stock 3.07 gears and add 33's to a six banger you pretty much cannot maintain highway speeds in fith gear anymore.

I don't really like people. I like to get as far away from people as I can. I need a jeep to do that. I like jeep people.

Simple enough for ya?

When I first started getting into Jeeps I would browse this forum for hours and hours just soaking up knowledge. I suggest you do the same, a lot will become clear.

Usually I don't respond to threads like this, but i'll give it a go:

Lift = more suspension travel and articulation offroad. better ground clearance.
Tires = better ground clearance, better offroad performance
gears = the ability to "crawl" easier offroad. easier to negotiate obstacles.

Lift = more suspension travel and articulation offroad. better ground clearance. only with a quality susspension , dont be fooled by a low price and don't be fooled by a high price , do your home work or you will get burned
Tires = better ground clearance, better offroad performance home work is key with tires as well
gears = the ability to "crawl" easier offroad. easier to negotiate obstacles. the right gears with the tire size is key , don't over gear or under gear , if you live or wheel in the hills or rocks higher gears are key , in the flats you can get away with a lower gear

Now for a more not so simple explanation.

Bought my jeep with a 2.5" lift and 31. 3.07' open. Wheeled it like that for a little over 2 years. Wanted more so I figured out what I wanted my jeep to do. That was I wanted to have fun with other jeep people running trails, rock climbing and basically having a great time with the people of this crazy addiction we call "jeepin". Also I wanted to take my family on vacation and see the wonderful places that God has graced us with on this planet we call Earth. So I built a jeep to get me to those places. Kind of funny cause I posted a picture of my jeep on my facebook page and a friend of mine asked me if I was building a "rock crawler?" I told him no I was not, but if it takes me to places only a few have ever seen and I have to crawl over a rock, well then I guess I am..

You see, there is not a cookie cutter definition on why we build our rigs the way we do. Every rig is unique to the person who built it. Find what your definition is, and go from there

I crunched numbers and honestly it's just about the same price if not cheaper to buy 2.5" lift then to buy stock springs. Majority of us YJ owners with stock springs have the springs looking flat as can be so I wanted new springs and went for a lift.

Oh and so stealing this!!

If you need a lift and bigger tires, you'll know it soon enough. If you wonder why you would need them, you don't.

Looks is a whole other reason, and as legitimate as any other.

Lift - added ground clearance plus additional clearance between axle and tub to accommodate bigger tires.

Bigger tires - more ground clearance. Potential for better performance off road. Bigger tires = more traction off road?

Everything revolves around the tires. Your axle clearance and approach and departure angles are greatly affected by the size of the tires. Lift is only there to accommodate the tire size at the body lines. Body lifts help get the transmission and transfer case up when getting the skid pan raised or tucked flush to the frame rails. Suspension systems work in several different ways to improve street ride, increase articulation and provide adequate lift to help tire fittament. Shackle lifts give up to an extra inch to the suspension lift but also give an extra arc for the large arched springs to flatten or droop.

The lockers you mentioned are differential lockers. Jerry explains it well here:
http://www.jeepforum.com/forum/f27/w...ad-4x4-242949/

Gearing is important to maintain torque ratios for the engine to compensate for the larger tires.

I'm pretty much rambling at this juncture.
