Sorry, this part is NO LONGER AVAILABLE.
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.
**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.**

BREAK IN PROCEDURE
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.)
EXPECT A 1.5-2 WEEK LEAD TIME BEFORE THIS ITEM SHIPS.
