Default 2.5 bb... What else do I need to replace with this...

Anyone know what else I am going to have to replace when I put on a teraflex 2.5" bb? I have heard the drive shaft I have heard exhaust spacers need to be added. But I have also heard nothing else needs to be changed out. Anyone know for sure from their own experience? No heresy please

You have a 2012, so you will need exhaust spacers. The driveshaft should been fine. Which bb kit are you going with? It should have new swaybar links and brakeline relocation brackets, minimum. Also, longer shocks or extensions.

The teraflex kit should come with everything needed, i.e. sway bar links, shock extensions and brake line bracket relocate. Call Dave at northridge 4x4 and he will help you out.

If you are using the kit with shock extension along with stock shocks and not exceeding 2.5" of lift you will not need the spacers. Only people using the aftermarket longer shocks will incur a problem.

Unfortunately you need it on any 2012, now you only need the front DS if you are 3" or over and some folks are not replacing the DS but if you are doing off road you may run into issues.

torn driveshaft boot on a 2012 JKU two weeks ago on my first wheelin' trip.

i have the 2.5" bb from teraflex with the shock adapters.

i read everywhere that "you'll be fine" - well i am fine with replacing my driveshaft now.

save yourself some money now and buy the exhaust spacers on any lift!!

after seing the damage i would say that anyone who will disconnect on a trail with anything more than a 3/4" leveling puck up front needs to add the exhaust spacer - period.

my neighbor was with me with the 1.5" leveling kit on his JKU and after i damaged mine, we looked at his and it was just too close!!

Thanks for the real world report..that's most helpful.

Being I have a Sahara and cannot disconnect do you think that would make a difference? My initial impression is that it should be OK as mine won't drop out as much.

If you have a 2012 with a TeraFlex kit with shock extensions, you will need the exhaust spacers #2610000.
