What size lifts require the exhaust spacer?

 

the problem isn't so much with lift size but rather, if the shocks you run are long enough to allow for too much droop. in other words, so long as you install a 2.5" lift with shock extensions or, install shocks that are short enough to limit your droop, you will be okay without the spacers.

having said that, even if you install spacers, lifting your jeep 3" or more will cause your cv joint at the t-case to sit at a steep enough angle that the joint will fail sooner than later. needless to say, you will need to replace your drive shaft at that point and time.

 

Thank you for the quick response, however Im still lost as far as the exhaust spacers go.

I'm in the same boat! I've been searching forums for weeks and decided I may just do a front 1" spacer or the rock krawler 1.75" leveling kit and some flat fenders with 33's and be safe for now since its my dd. later after my warranty runs out I'll do the bigger lift/ shafts/ gears.

 

the spacers just help your front drive shaft to clear it at a full droop. if you just install an aftermarket front drive shaft like you really should as it'll not only be narrower in diameter, won't have a slip shaft boot to get in the way and won't come into contact with the exhaust cross over, it'll actually address the issue you will have with cv joint failure on a 3" or taller lift.
