Fitment
Restore horsepower, compression and fuel economy to that tired engine with one of our factory replacement heads. Matches original performance flow and is available as a complete ready-to-install unit that's fitted with valves and springs.
These are the only NEW Jeep® cylinder heads (NOT rebuilt), available in the aftermarket today. Built with all new parts, these cylinder heads have been engineered to withstand the demands of aggressive off-road driving and will resist potential cracking and warping. The Jeep 4.0L and 2.5L heads feature hardened valve seats and heavier than stock castings to increase strength and durability of original equipment. Bare cylinder heads are also available less valves and springs. Gasket sets, pushrods and rocker arms available separately.
