Hamilton Cams Cummins 24V Hot Street 188/220 Camshaft Combo | 07-CC-24V188 | 1998.5-2018 Dodge RAM Cummins

The Hamilton Cams 188/220 Camshaft Combo enhances mid-range power and efficiency for 24V Cummins engines from 1998.5-2018. Designed for moderate to high-performance builds, this combo is ideal for enthusiasts using larger turbos or compound setups. It includes all necessary components to boost performance and reliability while maintaining proper engine clearances.

Features:

• RPM Range: 1700-4500, offering robust mid-range performance ideal for daily driving, towing, and competition use.
• EGT Reduction: Lowers exhaust gas temperatures (EGTs) by 200-300 degrees, preventing heat-related stress on components under heavy loads.
• Pushrod Strength: Heavy-duty pushrods designed to handle high engine loads, minimizing valve lift loss, bends, or retarded timing at up to 750 hp.
• Improved Power Delivery: Enhances low and mid-range torque for quicker turbo spool-up and smoother power at higher RPMs, ideal for both street and race applications.

Included:

• 188/220 Camshaft
• Heavy-Duty Pushrods (OEM to 3000hp)
• 103 Valve Springs
• Lifters/Tappets

This camshaft combo provides increased airflow and reliability, with components designed for performance builds and daily use. Proper clearance and break-in procedures are essential for optimal results.

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 with a clearance calculator, even for drop-in cams.
• Steel Cam Version:
  • Requires at least two bushings in the cam tunnel to prevent wear on the cast iron block.
  • New lifters are recommended when changing 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 to ensure quick oil pressure buildup.
• Priming Procedure:
  • Disconnect the fuel system and crank the engine with the starter until oil pressure is visible or oil reaches the rocker arms.
  • Limit cranking to 10 seconds per attempt to prevent starter damage.
• Initial Start:
  • Once oil pressure is verified, run the engine at 1200–1500 RPM for 5 minutes, then shut it down.
  • Adjust the valves after this initial run.
• Additional Tips:
  • If re-torquing the head, complete it before adjusting valve lash, as it can affect the settings.
  • Change the oil after the break-in process to ensure engine health.
