Hamilton Cams Ram 5.9 & 6.7 Cummins 188 / 220 Cast Camshaft | 07-C-188/220 | 1989-2018 Dodge Ram Cummins 5.9L / 6.7L

The Hamilton Cams 188/220 Cast Camshaft is engineered for 1989-2018 Dodge Ram Cummins 5.9L and 6.7L engines, providing enhanced mid-range power and reduced EGTs by 200-300°F. Designed for versatility, this camshaft is suitable for daily drivers, drag racing, and stock class pulling.

Features:

• RPM Range: Optimized performance from 1700 to 4000 RPM, improving responsiveness and efficiency.
• Heat Reduction: Lowers exhaust gas temperatures by 200-300°F, enhancing engine durability.
• Compatibility Requirements: Drop-in design requires specific piston protrusion and valve face depth; consult clearance guidelines for optimal fit.
• Installation Recommendations: New lifters are advised during installation; ensure proper lubrication and priming to avoid break-in issues.

Drop-In Cam Fitment Requirements:

• 12v Engines:
  • Piston protrusion: ≤ 0.025"
  • Valve face depth: ≥ 0.055" with a standard head gasket
  • Intake centerline: 99°
• 1998–2002 24v Engines:
  • Piston protrusion: ≤ 0.025"
  • Valve face depth: ≥ 0.038" with a standard gasket
• 2003-2018 Engines:
  • Piston protrusion: 0.018"
  • Valve face depth: ≥ 0.038" with a standard gasket
• Clearance Adjustments:
  • If piston-to-valve clearance is insufficient, use an oversized head gasket or cut valve reliefs.
  • Always verify clearances, even for drop-in cams (a clearance calculator can assist).
• Steel Cam Version:
  • Requires at least two bushings in the cam tunnel to prevent wear on the cast iron block.
  • Always install new lifters when replacing a cam.

Break-In Instructions:

• Preparation:
  • Apply a liberal amount of high-quality assembly lube to the cam and oil pump.
  • Prime the oil filter and ensure the oil system is pressurized before startup.
• Oil Priming Procedure:
  • Disconnect the fuel system.
  • Use the starter to spin the engine until oil pressure is confirmed or oil reaches the rocker arms (limit starter use to 10 seconds at a time).
• Initial Start:
  • Run the engine at 1200–1500 RPM for 5 minutes once oil pressure is confirmed, then shut it down.
  • Adjust valves after the initial run.
• Additional Tips:
  • If a head re-torque or “hot-torque” is required, complete it before setting the valve lash to ensure accurate adjustment.
  • Change the oil after the break-in procedure to maintain optimal engine health.
