Enjoy a proper header upgrade on your HEMI SUV
These Kooks long tube headers give your 5.7-litre Grand Cherokee or Durango a choice of 1-3/4" or 1-7/8" primaries, both with 3" outlets. Pair them with the matching front connections to build the exhaust around your own HEMI setup.
SKUs: 36102201, 36102401
Two sizes, matching connection requirement
Both stainless options include an O2 extension harness and require Kooks front connections. Choose the primary size around your engine modifications and completed exhaust.
Different years for the Jeep and Durango
The exact application covers the WK2 Grand Cherokee from 2011 to 2021 and the 5.7-litre Durango from 2011 to 2026. Those ranges are kept separate in the vehicle table.
