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.

The perfect throw-on athletic dress (with built-in shorts!)
Size: Small, Color: Navy Blue
I’ve been loving this athletic dress—it’s one of those pieces that’s both functional and cute, which is hard to find. The fabric is lightweight, breathable, and slightly stretchy, so it’s comfortable whether you’re running errands, going for a walk, or just chasing kids around all day.
The built-in shorts are a huge plus. They stay in place well and make it feel more secure than a regular dress, especially on busy days. I also appreciate the pockets—they’re actually usable and don’t feel bulky.
The fit is relaxed and flowy, which I personally like because it’s easy and flattering without clinging. The straps are adjustable, so you can customize the fit a bit depending on your height or preference.
I’d say it runs true to size for a looser fit. If you want it more fitted, you could size down, but I like the casual, sporty look as is.
Overall, this is a great everyday summer staple—super easy to style with sneakers or sandals, and perfect for travel or on-the-go days. I’ll definitely be getting more colors!

Perfect for summer days.
Size: Medium, Color: Deep Gray, Size: Medium, Color: Deep Gray
I absolutely love this little athletic summer dress. I typically wear a size ten and ordered this in a medium and it's a perfect fit. I have the straps short so way it doesn't look baggy. It is super soft and comfortable. It is breathable and a perfect cut and length for me so so I plan on wearing it all during hot summer days. This is very versatile and easy to style by layering different things underneath it. I have a gray and leopard sports bra that is a really close shade of gray so it almost looks like it's one piece. I plan to order the teal as I have a swimsuit top that will match that color spot on. It seems like it is good quality and should hold up well to normal usage. I like that it has really big pockets , but I likely will not use them often lol. I just like the fact that if I need to have pockets they are there.

Size down! But overall comfortable and cute and good quality
Size: Small, Color: Light Yellow
Overall it’s cute and comfortable, but my advice is to SIZE DOWN!!! I wish I would have, but I’ve already washed it so it’s too late. The straps are adjustable, but even so, I’ve had to tighten them as far as they’ll go. For reference, I am 5’1” and 125#, rectangle shaped/boxy body with a very small chest and I got a Small. The top gapes open on me and the dress is longer than I prefer for this style. Material/fabric is nice and good quality and it’s a perfect one-piece easy outfit for warm days. I like the yellow color too. It is tricky to find the right bra to wear with it, though. Got lots of compliments on it the first time I wore it.
