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 5.9L.

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. The secret to the outstanding performance of these cams are their ramp velocity and acceleration.

Features & Benefits:
  • Average 2-3 MPG Increase
  • 30-35% Smoke Decrease
  • Approximately 200 Degree 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!
    • 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.

When sending us your camshaft(s), 
please remove the gear(s) before shipping!


  • 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.

This Cam just works!!!!!!
98 12valve (Northern Alberta) 9/2/2015 7:42 PM
I replaced the cam in my 98 12valve with the big stick. One of the best investments you can do. Better fuel economy, smoother running. The power to pull right from idle to 2900 Awesome product that is worth every dime.
Very good improvments

This was one of the best all around upgrades on my 97 12 valve. It helped the turbo spool quicker, lowered egts, and helped power all around. I would recommend this to anyone who wants a better running 12 valve. Order #339923
