When lifting your 2012-2018 Jeep Wrangler JK with 3" or more suspension lift you will need to install this 22011 Exhaust Extension Spacer Kit to ensure proper front drive shaft clearance.

The purpose of this exhaust extension spacer kit is to move the cross pipe down and toward the rear of the Jeep to prevent contact of the front drive shaft during full droop or articulation travel..
