Sorry, this part is NO LONGER AVAILABLE.

As an alternative we recommend the Stage 3 Colt Cam, Here.

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.

No clearance issues or springs required
Lobe separation, higher lift and longer duration, improves air flow by approximately 30%
Reduces turbo lag, faster spool up
Greatly improved throttle response
Approximately 25% reduction in smoke
100 – 150° EGT drop
1 – 3 MPG increased fuel economy on average

Stage 2: This is very similar to stage 1 but with a longer duration and lift on the exhaust side for engines with a slight restriction—or if you just want a little more exhaust flow.

• RPM: Idle – 3000

**About core charge: The stage 2 cam is a reground cam so you NEED to send your core back to colt in the same package that the new cam came in to get your refund of $200.00. Also when shipping your core back to Colt Cams make sure you state Return and Repair and value of no more than $10.00. Customer is responsible for core shipping fees.**

ROCKER RATIOS:
12V - 1.75/1 INT/EXH
24V - INT 1.5/1 EXH 1.4/1

• 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 2^nd 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.)
