A little help/advice with suspension mods

Hi everyone,

I recently acquired a 2012 JKU Rubi that's pretty much stock. I'm ready to start the modifications.

I'm looking at around 3" to 3.5" for suspension lift. My local 4x4 shop only carries the BDS 3". It's $1k out the door installed. In all my research online, it seems like this will be a fairly decent (not the best, but also not the most expensive) for what I need. I have an appt. Thursday to get this done.

However, while looking at pictures online, it seems like with the tires that I want, I might want just a bit more space. I'm 90% certain I'll be going with Goodyear Duratrac 315/70r17 (35s). I came across a build thread of someone who was running pretty much that exact same setup (BDS 3" & Duratrec 35s) but he also had a 1" body lift added. I loved the look and clearance and pretty much want to achieve the exact same thing.

I called the shop and asked them about how much extra that'd be to add a 1" body lift on there as well while it's in there Thursday. He kinda squirmed at that and mentioned that'd probably run another $600 and that honestly the best thing he could recommend if I got the tires on there and wanted more space would be to just add 1" coil spacers and that would only run me around $150.

So, the advice I need, is to achieve basically the same look and clearance as the build I saw, would that be the route to go? Or is there any advantage to doing the 1" body lift instead of the coil spacers? If I do the 3" BDS and the 1" spacers, will my ride quality and dynamic change for the worse vs. the body lift?

Sorry for all the incredibly dumb questions, I'm very new at this, but would really appreciate the help.

Thank you!

He squirmed because a body lift is a pain in are arse to install. The lift itself is not expensive. The labor is what is gonna cost so much. I put a 3" body lift on my TJ, and it was awful to install. You have to extend fuel filler hose, transmission linkage, just an overall pain. May not have to do all of that with a 1", not sure. Point to my story, I would take the advise of the shop. 35's are spot on with a 2.5" lift. I don't know why you wouldn't be happy with 35's on a 3"er.

Do not perform any mod for looks alone, mod for function. I promise you if you plan your mods to improve function, you will have a Jeep that "looks" the way you want.

Shaun, thanks for the input! I think I'd probably be happy with *just* the 3" BDS lift, however, just in all the pictures I've seen another 1" in there definitely seems to look better to me and allow for a tiny bit more clearance. Probably mostly a personal preference thing, but I just thought it looked nice.

So in your opinion, following the shops advice of doing the 1" spacers is better than the body lift? I guess what I'm really trying to understand is if there are any downsides to doing the extra 1" that way. If they were the same cost, would it be more advantageous for any reason to do it the body lift route?

look at a rock krawler lift, I installed the 3.5 midarm and it sits a lot higher than 3.5.

another word of advice that I can not stress enough, you NEED to replace the stock bolts in your suspension or you WILL have problems down the road. swap the 14mm bolts for 9/16 x 3in and 9/16 x 2.5in grade 8 avaliable at tractor supply, etc.

these are 36's on a RK 3.5 lift, I only rub on my bumper.
