Colt Cams is proud to introduce our latest grinds for the Cummins 5.9L B series engine! We've worked long and hard to develop these great new profiles. We've dyno'ed some 50 different combinations of durations, lobe separation and installed centerlines to come up with the ultimate cam for your Cummins 5.9. We have a large quantity of new cast billets in stock ready for you! Our 5.9L Cummins cams are available in 6 stages. We are always willing to customize alternative grinds as well.

Stage 3: Nicknamed the "BIG STICK". It has gained the most popularity. This cam delivers the strongest mid-range torque and H.P possible, but still has good bottom end and drivability. No mods are required, but we do recommend a set of springs.

  • Average 2 – 3 MPG increase
  • 30 – 35 % smoke decrease
  • Approximately 200° EGT drop
  • Good to 4000 rpm

  • Follow Cummins installation instructions, use adequate amounts of assembly lube.
  • Retainer torque 44 ft lbs – use red loctite.
  • When using our retainer, clearance is required on C.R.
  • Always use new or re-crowned lifters! The cost for us to re-crown yours is $75.00 USD.
  • IMPORTANT NOTES:
    • C.R. cams cannot grind to stage 3, only to 1 and 2. You must use 24V 2nd core or new cast billet cams for anything over stage 2 grinds.
    • When using our new Big Stick Cast Billets, use 2nd gen. 24V lifters only. (From 1998.5 – 2002, use Cummins Part #3942565.)
    • If using C.R. lifters with larger head, (also heavier) make sure it clears the fuel pump lobe on # 5cyl., especially on the 12V engines. C.R. blocks are ok but you should still check. If your gear is not pressed on all the way, the lifters could touch.

CAUTION! IF USING AFTER MARKET CONNECTING RODS,
EXTRA CLEARANCE MAY BE REQUIRED ON CAM CORE!

BREAK IN PROCEDURE

  • Cam Lube on all lobes, lifter faces and oil pump gears.
  • Oil all bearing journals and lifter barrels.
  • Always turn engine over by hand before starting, check for clearances and proper timing location. 
  • Fire up to 1800 – 2000 rpm. for 18 – 20 minutes. 

Note: Most oil companies have taken out a percentage of additives that are meant for anti-scuffing for break in on flat tappet cams, so please ask your local auto parts professional for the best zinc additive they have and add it to your oil before you fire up your engine for the first time. (We prefer ZDD Plus.)
