What is involved with a 3.5" Lift?

I have a 2003 Jeep Rubicon. It is stock right now. I was looking to get a lift sometime soon. My first plan was to go with the rubicon express 2" budget boost with a 1" body lift. But now I'm also thinking maybe the rubicon express 3.5" lift possibly. I was wanting to be able to run at least 33 tires which from what I have been told the budget boost with body lift can achieve that. But then I started thinking for a little more money I could go with the 3.5 lift lol. So what would all be involved in the 3.5 lift? Would I have to change out anything or would the lift be all that is changed?

This is my daily driver, so I was thinking I probably shouldn't go too crazy lol. I don't do a lot of off roading, this is just mainly for road travel, but maybe a few trails here and there. I'm sort of on a budget with this, but I would be willing to splurge for the 3.5 kit if I wasn't having to change out a lot of things. Would there be a huge difference in height with these kits? Please help me decide, thanks!

Welcome, The re 3.5 kit is nice lift. Not sure which version you are looking at, as you can mix and match stuff in the kit depending who you purchase it from. But in general, you may need a new rear driveshaft, if you don't want to lower your t-case, and even with that you still may need one. Some jeeps get vibrations some don't. Other things to consider, Front and rear adj track bars, lower adj control arms. I have run several RE kits on my jeeps and have been happy with them. This should give you the proper room for 33's and some folks run 35's with this kits.

I believe that with a rubicon there is less of a chance with the vibrations because the rubicon uses a differant transfer case. Someone with more experience is gonna have to explain that more though.

You shouldn't need the SYE/driveshaft since you're driving a Rubi. Your transfer case has a significantly shorter tailshaft, eliminating the need to swap it out for less vibes. Saves some $ too!! You may need to use the transfer case drop kit, though, since all Jeeps are different. It should be included in the RE kit. I don't run the RE kit, but I've heard alot of really good things about them. I say go for it. You'll need new shocks, and definately go with a monotube design either from RE, Full Traction, or Old Man Emu. You'll never regret them. Welcome to the forum, and show us some pics of the old girl!!

i have an 04 rubicon and here's what I did when I had 3.5" on my jeep. Its all a bunch of mixed parts but worked great and I didn't have to invest the $$$ all at once.

- one pair of RockKrawler front lower control arms to correct caster and eliminate the death wobble

- 3.5" Rubicon Express front and rear coils (the box actually said 3" instead of 3.5 but they are 3.5")

- front adjustable RE1600 Rubicon Express trackbar

- teraflex rear track bar relocation bracket

- one pair of rear Rubicon Express sway bar link extensions

- removed the front stock swaybar completely

- one inch Daystar body lift

- one pair of Daystart 1" motor mounts (helps correct the rear driveshaft angle so its not so steep)

- longer shocks ( I forget the exact length but I had to experiment with a few different lengths to get it just right)

- still used the stock driveshaft and is NOT necessary to lower the tcase at all. The motor mount lift made that possible by helping with the rear DS angle.

I ran with that setup and 35" tires for a LONG three years of wheeling... and the stock control arms flexed amazingly well... they are also weak and were cracked and split in a few places by the time I upgraded to my current long arms.

In the long run I ended up paying approx the same price I wouldve with a full kit but I was able to piece it all together from other peoples used parts etc and the price hit was not bad over time. I wheeled the crap out of that setup and it was a ton of fun too.

I respectfully disagree with you tripp

a 1" body lift works great with the motor mount lift...
and the motor mount lift is necessary if you want to install 3.5" coils while keeping the stock rear driveshaft

I highly recommend the body lift and motor mount lift with any suspension lift. Even the Rubicon TJ, which doesn't have a slip yoke, still needs all of the help it can get especially if the stock rear driveshaft is being used. I'm still using the body lift and motor mount lift on my 5.5 xfactor longarm setup.

The body lift has a couple other benefits... easier for me to remove/install the front driveshaft since there is more room between the frame and the tub for me to fit my ratchets, extensions, and fingers in there... more room under the oil pan for me to raise my oil pan skid an inch higher... more room for the aftermarket gas tank skid and allows to raise it an inch higher... using the body lift and the motor mount together allows me to close the hood whereas if I just had the motor mount lift it would be too close... no mod required for tcase linkage if motor mount lift is used with a body lift... little details like that are cool... plus the fact you can run bigger meats.

Here is an old picture showing my jeep with the 3.5" coils with 1" body lift (1" motor mount lift is installed but obviously cant see it) the 1" helps





I can't think of a reason not to get the body lift/motor mount lift combo.

I remember nico talking about something like that.. some one did a 2 or 3" body lift and put a flat sheet of steel for a belly up. Looked like it was very nicely done. Obviously it wasnt much work since it was a flat sheet of metal however it was a very good idea.

Thanks for the help guys! So what about the Rubicon Express 2" budget boost? Anybody had any experience with that? Is it noticeable? My other option was the 2" budget boost with a 1" body lift and run 33s. What do you guys think about that lift? Thanks for the opinions!

I'm currently running a 2" BB with 1" BL with 33" MTs. As long as you adjust your bumpstops, you'll be ok. I've got 15x8 Eagle Alloy rims with 3.75" BS and no rubbing issues even at full lock. The ONLY reason I'm running this lift though, is because I haven't been able to install the 3" Full Traction suspension that's currently residing in a big box in the back of my Jeep

I say don't cheap out and do it right the first time around. You opted for the Rubicon, the best out-of-the-box Jeep made, now don't pull in the reins and get cheap on it. Save if you have to, but do it right. You won't regret it.

I ran the 2" budget boost on stock coils and it worked great. I later added some used 3" teraflex coils that were super soft and more like 2" instead of 3" since they were used. Worked great then too. but thats when I had to get front lower control arms to adjust the caster and avoid the death wobble... anything aroundd 4" of lift and that needs to be addressed.

But 2" spacers on top of the stocck coils and maybe even with a body lift would give you room to run 33s. Throw on some slightly longer shocks and your ready to rock

I installed the RE 3.5 std kit and I love it. The kit wasn't bad me and a buddy did it in a night. Im still running the stock track bars didn't have to do the front relocation. The kit came with everything I needed. I did do a temporary t-case drop which came with the kit. I plan on doing a sye in the near future but the jeep rides great I wouldn't have changed anything about my decision. The install was easy and the directions were pretty straight forword. I think you would be alot happier with this kit then the BB BL option. The jeep looks great with the extra lift and has no trouble running 33's. Like you have heard tho some have worse vibes then others! Just my 2c good luck!!

X2 - I did the RE 3.5" kit and bought their monotube shocks. I added adjustable JKS front coil spacers to level off the extra weight of the winch and RRC bumper.

Very nice kit, easy to install and it holds up very well off and on road.

If you ever see yourself wanting to go bigger then take a look at the kits that are upgradeable to a long arm kit. This gives you many more options. I don't think you can go wrong with the RE kit.
