Skunk2’s Ultra Series Camshafts for Honda’s K-series engines dramatically increase both horsepower and torque yet retain complete valvetrain stability and exceptional engine response. Ideal for heavily modified engines, Ultra Series Camshafts are manufactured from proprietary, high-quality forged tool steel cores, are CNC ground, and feature patent-pending profiles with unique lobe shapes and revolutionary lift, velocity, and acceleration characteristics.Up to 80 hp gains with Skunk2’s Ultra Series line of camshafts, Skunk's professional line of high-lift, racing camshafts for Honda’s K-series VTEC engines. Ultra Camshafts are designed to optimize mid-range and top-end horsepower and torque, with peak power moved up the RPM band. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible. No other line of racing camshafts even comes close to Skunk2’s Ultra Series. What's more, Ultra Camshafts are also the perfect addition to any high-output, turbocharged engine.
Skunk2 camshafts deliver unparalleled power as a result of continual, extensive development and testing. By utilizing advanced manufacturing techniques and the latest computerized simulation and modeling equipment, Skunk2 camshafts are able to deliver maximum power across the entire powerband. Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance. Each camshaft is manufactured of forged tool steel core, increased torsional strength, improved durability characteristics, and reduced frictional effects. All Skunk2 camshafts are ground to exact specifications using state-of-the-art CNC cam grinding machines equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces.
Skunk2’s Ultra Series Camshafts also feature Fast Ramp and AMAX profile technology, which increases overall performance and results in unmatched response from idle to redline. AMAX technology simply maximizes the area under the lift curve but without compromising reliability or valvetrain stability. Skunk2’s profiles feature more duration than competitors’ at lifts above 1mm, resulting in greater efficiency and more power. And thanks to Fast Ramp, the same technology used in Formula One racing, seat timing is reduced, which results in additional cylinder pressure and more torque but without compromising valvetrain longevity.
Skunk2 camshafts designs are the direct result of our years of drag racing and road racing efforts. In addition to each Skunk2 project car and race vehicle, the world’s top road racing and drag racing teams have relied on Skunk2 camshafts for years.

Worth it if your dog destroys plush toys & likes to chew
Color: Cyan NylonFish
My dog is a very big chewer and destroyer of toys. This toy is perfect for her. It is durable and keeps her engaged chewing for a while. I have a 55lb dog, considered a large dog, and it’s a great size for her. She’s unable to break it apart. The ends do tend to get a little sharp after extended use

My Boston loves this fish toy
Color: Cyan NylonFish
Very durable. It takes a couple of months of intense chewing to make holes in this toy. My Boston has incredible mouth strength so he destroys most toys in minutes unless they are rocks. I have replaced this fish 2 times in the last year. I keep an eye on the wear and replace it when he makes a hole in it. Worthwhile purchase but monitor the dogs chewing.

Great sturdy toy
Color: Cyan NylonFish
Great toy.
1 yr old puppy LOVES it! However, not good for TILE FLOORS. It's so strong and sturdy but bangs all over the tile! Enough to crack tiles 😬

American Bully Trial - Honest Review
Color: Cyan NylonFish
I have never gotten a toy that lasted more than an hour when it comes to my baby girl. She is an aggressive chewer and loves anything that squeaks. This definitely helped to keep her entertained and use her teeth. I can confidently say that this toy may last a long time but she has already ripped a piece from it. I didn’t expect anything less since she always knows how to test new toys lol. I would definitely recommend though and will be getting more for her once this one is gone. Thank you!

Hard, heavy, sharp
Color: Cyan NylonFish
This is very durable, but it is also very heavy (our dog likes to throw her toys) and after some chewing, the head and tail are very sharp
