4.0L/4.2L hydraulic camshaft designed for towing, super charged and turbo charged engines. The cam lift is .480/.480 intake/exhaust. The duration at .050 is 224/214 intake/exhaust. Smooth idle. This grind is also available for the Jeep 2.5L by special request only. Does not include lifters. Use PN:HL-2011S.
NOTE: The stock valve springs will have to be replaced with our performance springs and retainers or severe damage will occur. 1997 -up 4.0L engines will also have to replace the stock triple groove valves with the earlier single groove valves for the valve stem tips to protrude up far enough for the rockers to contact them. When replacing a later cam with the small timing gear journal you will need an earlier 4.0 timing set, cam bolt, and washer. |
