Namura piston kits come with the piston individually wrapped; a set of OEM quality rings packed in their own box, a wrist pin, and circlips.
- MOS2 (Teflon/Molybdenum) Coated Skirts: A rolled-on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction, and helping to eliminate cold seizures.
- Machined Smooth Heads: Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%.
- Anodized Domes: Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons.
- Hypereutectic Casting Process: Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.

Nice flat bill hat
Size: One Size, Color: White
My husband says this is a comfortable hat. It was a little hard to shape up when it arrived, but overall the quality of the hat is nice. Nice and white and a mesh back to it. The design is a burnt orange color. Nice fit and adjustable in the back.

Unisex
Size: One Size, Color: White, Size: One Size, Color: White
I’d definitely call this a unisex hat, I like it as much as my husband does! Nice true white, the embroidery is great and it’s a classic style. This is very well made and comfortable, I would purchase in additional colors!

Yeehaw Energy Activated
Size: One Size, Color: White
Put this on and suddenly I feel like I need to buy a truck and start two-stepping. Sharp design, solid fit, and the spurs logo gives just enough Western flair without yelling “rodeo clown.”
One star off because the white gets dirty faster than a cowboy’s boots after a rainstorm. Still, great hat if you're chasing cowboy cool.
Also, have had a few people ask where I got the Texas Longhorns hat...
