For all Chrysler, Jeep, Dodge, & Mitsubishi 4.7L engines. Detailed instructions on how to upgrade to the 08 and later camshafts and while I have it apart I'll replace the valve stem seals and install the replacement HO valve springs (part number 53020749AC) with new retainers. I use a tool that I built to compress the valve spring allowing both hands to be free to remove and replace keepers, retainers, valve springs, and valve stem seals. Work performed on 2004 Jeep Grand Cherokee.
The 2008 & later Camshafts had a couple different part numbers
LEFT: 53021979AA or 53021983AB
RIGHT: 53021980AA or 53021984AB
2008 Camshaft spec. Int. Duration @ .050 236 with .277 lobe lift. and Exh. duration @ .050 252 with .257 lobe lift. 110 LSA with a rocker ratio of 1.85:1 that give a valve lift of .512 intake and .475 exhaust
If you are interested in the Martinbuilt valve springs compressor I have them currently available for $86.00 with free shipping. I have made upgrades to the one you see in the video. The aluminum plate has been water jetted to precision and comes complete with a retainer cup and hardware.
