Good To Know

Q: Does this cylinder head come with valves and springs installed? A: Unless the listing photos show them, this is a bare cast cylinder head, so you will need to transfer or source valves, springs, and retainers. Check the photos and description carefully before buying.

Q: Will this fit any 4.0L Jeep engine? A: It is intended for the 4.0L inline-six used in Cherokee XJ, Grand Cherokee WJ, and Wrangler TJ models. Confirm your exact year and engine code before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
