188/220 Cam Outperforms All the Other Cams

If you are looking to take your engine performance to the next level, then you are going to need a high-quality cam to get everything moving. The 1989-2018 Ram Cummins Hamilton 188/220 Steel Cam outperforms all competitors out there at all RPM ranges from idle to 4,200 RPM. It is a simple, drop-in replacement that is to be used with 62mm or larger single turbos or larger twin turbos. During installation, you will also need an intake on a 99 centerline, performance springs, and performance pushrods. If at any point you surfaced the head or block, you will need to make sure that there is adequate piston to valve clearance.

Fitment: 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 Dodge Ram 2500/3500 5.9L/6.7L Cummins

Modifications Required:

• For it to be "drop in" on a 12V you will need no more than .025" piston protrusion and at least .055" valve face depth with a standard head gasket and a 99 intake centerline. On a 98 - 02 24V you will need no more than .025" piston protrusion and at least .038" valve face depth with a standard gasket. On an 03 and up, it needs .018" piston protrusion and at least .038" valve face depth with a standard gasket. If you do not meet the minimum requirements for piston to valve clearance, don't worry, you can still run an oversize head gasket or cut valve reliefs.
• Although this is considered a drop in cam it is important to check clearances (You can use our clearance calculator to make it a little easier).
• For the Steel version you will need atleast two bushings installed in the cam tunnel, otherwise the steel could eat into the cast iron block.
• We always recommend new lifters when changing a cam.
