Assuming u have a 4" lift on a 2007-2011 JKU...Obviously your stock driveshafts are gonna be getting pretty short at this point, so u realize u need new ones...My question is...How much longer if the aftermarket shaft from the OE stock shaft for the front and rear?Is it an extra 3/4"?, 1 inch?, 2 inch? Just very curious in regards to this. Any info would be appreciated!

 

It's depends on the amount of pinion angle u want to run but u actually want to take measurements. The drive shaft design will also dictate what pinion angle u should shoot for. Look at aftermarket driveshaft websites for more indepth info.

 

I get it, it all depends on the pinion angle etc. but, if u were to buy eg. a tom woods driveshaft online from quadratec or any fine sponsor for your newly lifted 4" Jeep I was just curious as to what length increase total the new shaft would be.
