Swapping only the cam leaves stock springs and pushrods as the weak link. The Hamilton Cams 178/208 combo upgrades every part of the 12 valve valvetrain at once. It fits 1989-1998 Dodge 5.9L 12 valve Cummins. The cam itself fits 1989-2018 Cummins.

Includes: 178/208 camshaft, extreme duty pushrods rated past 2,000 hp, 155 lb valve springs, retainers and locks, and 1.45 inch lifters. No core charge applies to this part.

Key Features & Benefits

• Use: Quickest spool and widest rpm band of the Hamilton cams, built for towing with springs that control the valvetrain to 4,500 rpm and 80 psi of boost.
• Drop in: Drop in on a 12 valve needs no more than .020 inch piston protrusion and at least .055 inch valve face depth with a standard head gasket and a 99 intake centerline. Otherwise run an oversize head gasket or cut valve reliefs.
