1989-2019 Cummins 5.9L / 6.7L Colt Cams Stage 3 & 4 "Big Stick" Camshaft
PowerHouse is proud to carry the latest grinds from Colt Cams for the Cummins 5.9 - 6.7L B series engine! These camshafts have been 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 - 6.7L 12V & 24V.
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
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 if revving over 3000 rpm.
- Average 2 – 3 MPG increase
- 30 – 35 % smoke decrease
- Approximately 200° EGT drop
- Good to 4000 rpm
At the bottom of this page are the specs for the stock and performance grinds. The secret to the outstanding performance of these cams is their ramp velocity and acceleration.
Stage 4: Cummins 5.9 -6.7. Similar to the Cummins stage 3 but runs a larger EXH profile. Great for max flow on large singles or compound turbo.
