Swapping the stock manifold for a header is one of the first moves on a 4.0L that has a trail build in its future. The job goes better when the flanges, gaskets and hardware show up together.
The Rugged Ridge steel header has flanges welded 360 degrees so the joints stand up to heat. The bolt-on kit comes with a manifold gasket, hardware and a down pipe flange gasket, and Rugged Ridge backs its headers with a limited 5 year warranty. This one is finished in black. It is sold for racing and off-road use, so check local rules before installing it on a street Jeep.
5 year limited.
For racing or off-highway use only. Not legal for sale or use in California or other states that adopt CARB standards.
