Is the driveshaft required on the 3” JK lift?
No, the ICON high clearance drive line is not required on all year ranges. JK’s from 2007 to 2011 do not require any modifications to the drive line or exhaust. JK’s from 2012-2018 require an aftermarket high clearance drive line (ICON Part #22014) OR the ICON Exhaust Extension spacer (ICON part #22011) to avoid interference between the factory drive line and exhaust manifold.
