I've been lookin at the 2.5" TF BB and really like the size and the price, but all my friends outside the forum say that ill deff have problems with my rig after i put any type of lift into it. what kind of problems would i b looking at by lifting my jk 2.5inches? they said drive shaft problems will deff happen to me. i also had a question about shock extensions. they dont come with the 2.5 BB kit. I was wondering if by purchasing them seperatly it would reduce my risks of those problems happening. one last question is how well the TF BBs handle on rocks? please guys help me out

 

You need to download the 2009 TeraFlex catalog from my sig line below. TeraFlex offers 3 different BB 2.5" kits and 3 -2.5" Coil kits. It depends on what kit you buy as to wither or not shocks/shocks extensions come with it. Sounds like your looking for a #1355210 on pg 10. Many forum users are running stock shafts with these kits. Look up jkkat and her pics.

 

I ran my 2-dr for 2 years on the TF BB w/ shock adapters and stock shafts. It gave me no trouble at all, and I'd recommend it to anyone who wants an inexpensive lift.
It doesn't increase the range of the suspension, so it's mostly a looks lift, but you can squeeze 35's under there if you want.

 

My neighbor.......

I have the TF BB and have been running it for close to 2 years now. I do A LOT of wheeling, and hard wheeling at that. There are NO driveshaft problems. There are NO suspension problems. There are NO vibes. I can do 90MPH all day long in it (but I don't). I told you, if you need help or assistance, I'm right around the block.......literally. Swing by and I can show you my setup and answer any questions you may have.

 

That is true, to some extent, but not quite as rough as they make it sound. It's just a fact that the higher you lift, the more you need to do to bring it back to that 'stock' ride. (and also depends on what handling characteristics you're willing to live with...)

If you haven't done so already, I'd suggest starting here for some basics: (try the suspension, then the tires, and even the axles faq's)

But with any lift:
-Your axles will be off-center - Add brackets or longer or adjustable trackbars to correct.
-Your caster will be lower, causing flighty handling/bumpsteer/etc. The fix is Cam Bols (which are inexpensive, but have some drawbacks), or new longer/shorter control arms, or adjustable control arms (which are preferred)
-Your brake lines may be stretched too tight when flexing. Drop brackets or longer brakelines will help.
-Your tires may rub suspension components/bumper/skidplate/etc. Various remedies, but trimming, different backspace on wheels, more lift, extended bumpstops, dialing in steer stops, etc.
-For drive shafts, 3" is generally the place you want to start looking into new ones. (depending on other factors, but ya know) At 2.5", if you have an automatic, you may run into a problem with the front shaft contacting the skid or the corner of the transmission. Trimming and/or lowering the skid a bit would not be a bad idea. And pulling off the metal band that is on the driveshaft boot and replacing it with a zip tie for added clearance is also good.

None of these should be major issues with a 2.5" BB. If it doesn't bother you, then don't worry about it. It just comes down to preference on how bad 'you' think they are, and whether you want to do anything to correct them.

 

Looks like you have a JK buddy close by to aid you. Now you just need to decide what kit you going to buy and put it on. I have had no issues with any of the TF BB kits I have helped with. Best of Luck

 

The TF BB comes with the rear trackbar bracket to re-center the axle. I bought a TF front adjustable trackbar, re-centering problem solved.

I have stock control arms and don't have flighty steering. I have no pinion angle problems either. BTW, cam bolts SUCK and should NOT be used.

The TF BB comes with rear lowering brackets for the brake lines. At full flex WITH FACTORY bumpstops, my brakelines are not fully stretched and is NOT pulling on my ABS wire.

With 285/75R16 tires on factory steel wheels I have MINOR rubbing at full lock. But, used one washer on the turnstop bolts and problem solved. There's nothing a torch can't cut off (a little off the skidplate).

Like I said, I'm running factory brakelines, control arms and springs. My BB has been working phenomenal with all the wheeling I do without a single issue.

 

OP is asking what issues he 'might' run into. I thought my post was fairly accurate.

As opposed to your first post saying NO issues. And your second post listing :
I bought a TF front adjustable trackbar
TF BB comes with rear lowering brackets
rubbing at full lock
used one washer on the turnstop bolts
There's nothing a torch can't cut off (a little off the skidplate)



Oh, and what issues did you have with cam bolts? If I were to guess, you've actually never used them...

 

He's worried about having problems. Issues are different. Issue is something that can easily be corrected, problems cost money to fix.

The front trackbar is not needed because PLENTY of people are running with the axle not centered. I didn't want to rub on lock to lock so I added a washer, for FREE. Issues can be addressed. There a thousand people or more on here with a TF BB and you're telling him you might run into this and that and blah blah blah. I'm not arguing with you, just stating what I ran into and with the TF BB and it's not that big of a deal.

I don't like cam bolts because I don't like the fact that you have to modify your control arm mount to accept it, and generally, hard to go back without fully cutting off the bracket and welding a new one in. Had 'em in my TJ, would never do it again

So before you get sand in your vagina, ease up.
