1989-2018 Cummins Stage 6 Cast Billet Camshaft (C.784.S)

Fits

These Stage 6 camshafts from Colt Cams will give you a longer duration & lift on the exhaust side for motors with a slight restriction, or if you want more exhaust flow and great for max flow on large singles or compound turbo setups.

Part Number: C.784.S

• Valve lash all grinds: INT: .010" EXH .020" cold
• Good to 6500 RPM
• Full race/ sled pull applications
• Thicker core and fillet radiuses in front of both journals on #1 cyl - This strengthens cam for less chance of breakage
• Colt Cams heat treats them in a very unique way again for less chance of breakage and lobe scuffing
• All the cams are parkerized. This is for the initial start-up, break in procedure. Parco lubrite is a graphite coating done in a hot acid bath. This allows your cam lube something to hang on to and puts a barrier between your tappets and lobe so no hot spots can occur from metal on metal. This is another important detail for longevity.

• Colt Cams Tappet Set is highly recommended
• Valve clearance required
• Retainer torque 44 ft lbs – use red loctite.
• Due to many contributing variances in an engine: heads planed, block decked, valve recession etc... any cam including stock, should always be checked for clearance before start up!
