PPE Stage 1 Performance Camshaft 01-16 GM Duramax LB7-LMLAlright, so you've replaced your exhaust and intake, and didn't see enough power gains. You want more for your 2001 2016 Duramax, so you install injectors, a bigger turbo and get a tune. Still not enough, or maybe the power band from the factory just isn't where you want it and you want more out a tune. Time to talk camshafts. While yes, the air available for your truck starts at the intake, but it still has to make it into the cylinder. Camshafts
Alright, so you've replaced your exhaust and intake, and didn't see enough power gains. You want more for your 2001-2016 Duramax, so you install injectors, a bigger turbo and get a tune. Still not enough, or maybe the power band from the factory just isn't where you want it and you want more out a tune. Time to talk camshafts. While yes, the air available for your truck starts at the intake, but it still has to make it into the cylinder. Camshafts control the length of time that your valves stay open and how far they open, dictating how much air and fuel can make it into the combustion chamber. By swapping out the camshaft, you can (within reason) change that duration and lift to a timing that better suits a mid to higher rpm range, or lower depending on the configuration.PPE (Pacific Performance Engineering) presents the Stage 1 performance cam for the 6.6L Duramax in standard and alternate firing order configurations. Featuring a moderate intake/exhaust duration, and a .470" lift, this is an ideal camshaft to match with near stock or moderately tuned engines. With power production focused below 4000 rpm, you can expect low-mid range power increases, without sacrificing low end torque. Also, no modifications are necessary to the heads of your pistons unlike some aftermarket cams.
For trucks producing larger power numbers, or for those aware of the crankshaft failure rate at higher power production numbers, PPE also offers an alternate firing pattern version of the Stage 1 cam. For those not familiar, as you produce high power, there are little vibrations that develop and lead to failures of the crankshaft. One remedy for this is an old hot-rodders trick, of changing the firing order. The result is a change in the location of those harmonic frequencies, similar to moving a subwoofer away from a wall. With the resonant frequencies relocated, the forces and science that's happening in all that metal are redistributed more evenly, promoting reliability and less change of failure.
NOTE:
- When converting to an alternate firing order camshaft, you need to re-pin your injectors to correspond with the changes.

Know what you're doing before you order
Color: Grey
There's a very high quality item easy to assemble last a long time it was pretty nice. For the first one. My roommate talked me into buying the second one and then he backed out of the deal he didn't have the money. So I returned it at the Amazon store and like a boomerang it came back. I end up having to buy it anyway you're still sitting in the box

Must have for at home workers!
I bought this divider because I work from home and wanted to have a professional and neutral background for video conferencing. There were other dividers that I contemplated purchasing because of the variety of colors but ultimately decided to go with this divider because of prime shipping. I noticed in the reviews of other dividers on Amazon a lot of people talked about cracks. I noticed a few cracks on mine but they are small and minimal in appearance so it does not bother me (see pictures). Overall, it came in great shape. I love the color of the divider. I was concerned it would come solid brown based on the pictures but it is more rustic, which I love. The dividers are tall and long so it covers a great amount of space. The hinges go either way which is also a plus. I will say it seems slightly unstable on carpet but it would only move if bumped into so that is not much of a concern. Most likely would be more sturdy on solid/ hardwood floors. Overall, I am super happy with my purchase. Definitely worth the price with fast 2 day prime shipping and no assembly needed.
