Wiseco sport compact pistons are forged and machined in-house and receive a full compliment of power enhancing features. Light weight forgings, millimeter ring packs, extra-strength forgings, gas ports, skirt coatings, offset pins, and a variety of other features are available to insure each engine exceeds our customer’s expectations. Optimized skirt profiles minimize rock and provide long skirt life in stroker applications. 

All machining is done on the newest CNC equipment to insure the tightest tolerances in the industry. Our Wiseco sport compact pistons are top of the line performance parts, built for the demanding consumer that wants nothing but the best. Some of our sport compact pistons are even matched with high quality NPR Steel nitrided rings with napier style 2nd rings.

Below are just some of the popular features found in our forged piston product lines:

  • Valve pocket designs allow maximum flow around the valve, allowing the use of oversized valves and high lift cams.
  • Piston crown shapes are designed to promote the maximum intake charge efficiency through a scavenging mixture ‘Cross Flow’ during intake and exhaust valve overlap. More fuel and air equals more horsepower.
  • Piston domes are designed for optimal quench during the compression/ combustion cycle, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.
  • Precision machined ring grooves with proper orifice/ accumulator volume feature calculated groove root diameters and axial widths, providing excellent surface finish and flatness, maximum ring seal, and minimized blow-by and oil consumption.

The ultimate "cozy" blanket—thick, soft, and incredibly warm
Color: 03- Tie Dye Black, Size: Throw (50" X 60")
his Bedsure blanket is the definition of comfort. One side features a velvety smooth faux fur while the other is a thick, plush Sherpa fleece. It’s significantly heavier than a standard throw, making it perfect for cold nights. The black color is deep and rich, and I’ve been impressed that it doesn't shed at all, even after several washes. It drapes beautifully over a couch or bed and adds an instant touch of luxury to the room. It’s the perfect size (50"x60") for curling up with a book or a movie.

Buy this now!!!
Color: 15- Teal, Size: King (108" X 90")
This is probably one of my favorite purchases from Amazon. I have washed it at least 10 times so far and it still looks the same as when I bought it. It is so soft and snuggly I love it so much. The color is beautiful the furry side is soft and the bottom side has Sherpa on it which is also soft. It's not super heavy and it keeps me warm and it fits my king size bed perfectly. It is such a good value for the money and the quality of it is amazing do yourself a favor and purchase this you will get the best Sleep Quality of your life I swear. I wish I would have had this years ago I don't know what took me so long to find it I have bought several blankets and ended up throwing them away because I did not like the way they felt. This one will be a keeper.

Soft and comfy!
Color: 06- Beige, Size: Throw (50" X 60")
The material is very soft and thick, but not to the point where it makes me feel hot. The only reason why it hasn't received five stars is because I ordered the twin size thinking it would give me good coverage (and I didn't want to order a bigger size), but it's just an inch or two too small for my body. But it's not a big deal. I love the quality too! You will get your money's worth for sure.
