lift question

I currently have a rubicon express 5.5 inch lift. I need new shocks and am thinking about replacing the springs while im at it. Does anyone know what all I would need to change if I wanted to go to the rubicon express 7.5 inch lift cuz the website says the shocks are the same for both and the springs aren't much more expensive to go up th two inches. Any help would be appreciated

Are you running 42" tires? Because 7.5" RE springs are actually closer to 9" of lift.

As for what you would need to change, probably brake lines, and bump stops. And bigger tires, which will mean big axles with more WMS, better brakes, stretched WB, deeper gearing, HD TC, etc.

X2 Thats a wholeeeee lot of lift there boy. Really there is no need for that much lift either. Its just raising your center of gravity dramatically increasing your chances of a roll over. Look at Lances rig. His running about 6 inches of lift. On 39 inch tires. His center of gravity is low so his chances of rolling arent as high (even though it looks like he rolls it all the time ) Plus the other thing to think about is yes your gaining clearance in the middle of your jeep but thats not the lowest point of your jeep. The lowest point of your jeep is your diffs. The way to lift those is bigger tires. You probably could do 37's on the lift you have now and have a very capable jeep. Good luck bud.

The highline fenders would be your best route. I wouldnt go any higher then you are now. But what axles are you running? I hope you already upgraded them to take the bigger tires.

Your better off with a Hi-Line kit for the fenders and keep the a low COG.

What size tires are you planning on running????
Rubi axles are only good for 36 maybe 37s with the right axle shafts.
If you get chromoly rears and the RCV fronts you should be OK on 37's but still need to be easy on the skinny pedal.

If your planning any bigger then 37's you might want to think about Ford 9's w/ big bearings or D60's front & rear

Once you start getting that big of tire other issues will be Hub Assemblies, Ball Joints and DS U-joints.

based on your profile pic it would appear you have room for 37's. But I would think about upgrading your shafts with that size tire, steering, brakes etc.

There will deffinetly be a lot of room in those fenderwells. I plan on going to 37's with a highline kit and a bit of lift myself. But I'll be doing the super 8.8 kit and superior shafts and install kits to a Dana 44 front.

I need to find out what shafts and stuff my axels have. I bought my jeep less than six months ago and whomever owned it before put alot of money into parts and upgrades. And it looks like they crawed it or something cuz the muffler is all dented up and that's a long ways off the ground

Ahhhh ok... sooo see you need to get out wheeling it before thinking of needing bigger tires. A rubi on 35's is quite capable. I'm running 33's and soon moving up to 36/37s and I can hang with guys runnning 37s. Sometimes I have to take a different line but I can still make it thru alot. I ran my rubi stock for a year before lifting it.

The key is... you need to get out & wheel your rig so you know what you & the jeep are capable of and also learn more about your Jeep too.

Depending on whewre your at and whats in your area or near you.... just plan a trip, people are always willing to go wheeling and will probably chime in as well.

So.. see plan a trip and get out there and enjoy what that RUBI was made for... wheeling the piss out of it, not daily driving... lol

That's the sole reason I bought mine back in 05, to wheel the piss out of it.

I'm in NE Ohio and will be hitting Rausch Creek this spring summer, since I have not been there yet.

I actually now only have 4" of suspension lift and 1" BL. The BL is just for the fact of my swapped in t-case needed the extra tub clearance. I run 39s. I am also about 10" wider than TJ width axles(70" WMS where TJs are 60.5" WMS), and 17.5" longer WB(111" WB where TJs are 93.6" WB).

Stable as heck.
