are any additional parts suggested or needed?

I have had it in my head for a few weeks to go with the AEV 2.5 coil lift and 315s. I am second guessing and wondering if a BB is all I need. my wheeling is limited to the hunting club and dirt roads.

Just not sure if a BB with shock extensions is going to ride any different than what I have now. Do I need an adj front trackbar like what comes with the spring lift etc.

 

It really comes down to how complete you want it to be. At heights below 2.5" changes in the suspension are minor but everything under the jeep has the geometry changed and things shifted. This has an affect on the ride of the jeep but many will not address it due to the cost or lack of knowledge on the subject. If you want the axles to run in the same track then an adjustable front track bar and a raised rear axle side track bar bracket (same height as the lift) will put them back in line and improve the ride. Correction brackets will increase caster and drop the control arms down so they are more level, which is what you want for the best ride and to minimize axle shift during articulation.

For most people a simple puck lift is more then enough and even those that praise the coil lift don't know how to properly set up the suspension to maximize the travel of longer coils.

There is more if you want to read the red link in my signature.

 

BBs have a much less steeper cost curve so if it's just hunting and fire roads, don't bother with a coil lift. At 2.5" u get into drop brackets/control arms, etc etc yada yada. Spend $150 and see how it rides and go from there. I'd stick to 2" or less. I know they offer 2.5" spacer lifts, but...

 

I have read your write up and it is the main reason I wondered if I was over thinking the whole setup. I don't want the flat fender look though and was curious if the BB would be enough clearance, and then the track bar issues I have talked myself in circles about this for a couple of weeks now. The cost difference is not really a factor but there is no reason to throw money away knowing what I'm actually going to do with the jeep is less than the current capabilities. I just want bigger tires and a little more belly clearance.

thanks for the response.

 

One other piece to the puzzle is that you will want to move the new 35" tires further out. (wheel spacers or rims with less backspace). When stuffed, those taller/wider will likely be contacting the lower lip of the fenders, rather than tucking up inside as they do now.

You may be able to add some bumpstop to minimize the contact, but ...

 

I don't have a rubicon so no electronic discos, makes it less likely that I will disconnect very often if at all. am I going to stuff them in the fenders connected? honest question still trying to learn . I dont' want to blow money on something but am not opposed to spending to do it correctly the first time if that makes sense.

 

With a 2.5" lift (Spacer or Spring) you are most likely still going to be tucking that 315 into the wheel well pretty tight with the sway bars connected.

Like Dirtman and others have said, the trackbar isnt essential, but will better guarantee that things line up like stock. A track bar is expecially good to buy if you are scared that your 315s are going to make contact when stuffed (You wouldnt want your axle shifted over more to one side making contact)

 

I plan to run 1.5 inch spacers on the stock wheels no matter which route I take . I like them

Would a more narrow 33-34 be a better choice like a 285/75 or a 295/70 or will the 315s work fine with a 2.5 BB?

 

My JK had a 2.5" spacer lift and adj track bar on it when I bought it.
I did not like the squirrely nature of it. I would suggest you add to your list something to correct caster (control arms or relocation brackets).
Once I had that sorted out, it was fine and dandy.

 

It depends on the BB you choose.. Some are complete, some are not. The TeraFlex 2.5' Performance BB is the exact same parts as their 2.5" spring lift .. Only difference is spacers versus springs..
If you already have, or will be getting, heavy bumpers, armor and/or winch go right to a spring lift. If you want the same ride you have now and dont intend on all that heavy gear for quite awhile just get the BB.. The spring lift will ride harsh without the extra weight they are designed to handle..
