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 only balls that have lasted with my dogs.
Color: Orange, Size: Large
I own a Southern Black Mouth Cur and a Belgian Malinois. They have destroyed every other ball I purchased in a matter of minuets, except for these. I will not waste my money on any other brand!! Also come in large and small sizes, for at home backyard play or carrying in a pocket. Okay, so my dogs have now had these balls to play with for months and finally put tiny holes in both. The holes are so small you can't see them, but you can hear air escaping when they chew on them. One actually folded in on itself one time but I was able to pop it right back out, throw it again, and watch my happy aggressive chewer catch it on the first bounce. And they both still bounce well! These Chuck It balls are easy to find if left outside because of their bright orange color, rinse off easily with just water when muddy and grunge covered from outdoor play, or you can use any soap or cleaner you prefer without damaging them. Perfect for any dog, big or small - indoors or outside in the dirt. Love these!!

Won't go through "hurricane" or chain-link fencing - dogs LOVE it.
Color: Orange, Size: Large
We've been using this size (large) for about 2 years now. Between our Doberman pinscher and the boxer-pitbull mix, they are tough on toys. These dogs have access to the Chuckit Ultra balls only under supervision and they run like crazy in the backyard while either fetching or holding onto the balls. It keeps our doberman out of trouble because she's running with a ball in her mouth and therefor cannot nip at the other dog when she gets overly excited. Tennis balls are lucky to last one play session with these guys, just for comparison purposes. When throwing the regular size, the ball occasionally went right through our backyard (chain link aka "hurricane") fence -- even though they shouldn't quite fit. The size large balls bounce off the fence; our only problem now is when one of the dogs does a soccer style head-butt and knocks the ball over the fence that way. After 2 years, one ball has a split down the side and two are discolored because they were left outside when we couldn't locate them after a play session. Overall I like these very much and appreciate how well they've held up.
