Is it recommended that you replace your 4 cylinder engine with a 6 cylinder to go bigger on tires and lift, and is it difficult?
*Diesel* 4 cylinderIn all reality you can use the same engine just regear for the tires. Dirt every day has a Jeep names tube sock. That started as a 4cyl they ran 37s on it just fine. Now of course they did bigger axles but gearing was key to good performance.

I was thinking 33 tires.Yeah, I don't think Tube Sock spent much time on 37s with the stock 2.5L!
To answer @Tiffany LeBlanc 's question...No, you don't need to change the motor to lift and / or run bigger tires. Just need to get more gear (numerically higher numbers)
How big do you want to go?
4.88 or 5.13 gears, upgraded 27 spline alloy axles and drive it in a reasonable manner should work just fine on the street and for mild off road. Anything more abusive will require a locker of some type so you can upgrade to larger 30 spline axles.I was thinking 33 tires.
Im sorry I dont know what you mean when you say gearing, or what gear I will need.No problem...Definately don't need a new motor for 33's Some of the other gearing experts will have to chime in with what gear you need though...Maybe @Rob5589 can help.
By gearing, we are talking about the physical gears in your front and rear axles. Also gearing is the final drive ratio.Im sorry I dont know what you mean when you say gearing, or what gear I will need.
So, your engine drives the wheels through a transmission (the thing you shift) and then to the rear axle. In order to make the wheels roll forward or backward, the power needs to "turn a corner" if you will. In other words, the engine, being arranged as it is, spins counter clockwise as you look at it from the drivers seat. If you were to let it move, while its in that orientation, it would go left. Follow?Im sorry I dont know what you mean when you say gearing, or what gear I will need.
So how do I know what ring and pinions I need?

Math, experience and a little magic. There's charts out there that will tell you a recommended gear ratio, that's the math part. The charts usually use tire size and speed to determine a recommendation. There's more to it than that though. How you use your rig, where, the transmission...that where the tribal knowledge here comes in. The charts will get you close. The common pool of experience will get you even closer, if not right on.So how do I know what ring and pinions I need?
