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.

These shoes are adorable but they run large
Size: 11, Color: Champagne
Dream Pairs Low Chunk Heel Size 11
Color
These shoes are absolutely gorgeous. The beautiful champagne color shines so exquisitely in the light. They are very shiny and somewhat sparkly. They are definitely eye catching.
Style
These shoes are great looking, rather sharp. I appreciate the chunky heel design which goes with many outfits from dresses, pants, and jumpers.
Size
I usually wear a size 11 shoe, sometimes a 10.5 depending on how they run, but these run large in length. I could have easily bought a size 10 for the length of the shoe. My left foot is smaller than the right foot so usually the right foot fits more snug. I definitely still had room in the back for the right foot, but of course, even more room in the back for the left foot. In terms of the width, the toe strap very well accommodates wider toe boxes, as the straps fit properly right out of the box, but the arch of the shoe is a little narrow. Nothing too noticeable but the fit of the shoe is a little odd.
Versatility
I find that these shoes can be worn with many different styles and outfits, and can go with dressy or casual clothing. The variety of matching outfits is not limited.
Comfort
These shoes are very comfortable to wear and walk in.
Overall, I recommend these shoes

Perfect heel!
Size: 11, Color: Gold/Glitter
Love these heels! I bought the gold and wasn’t expecting them to be most glittery. They are beautiful and comfortable! The heel is chunky enough that these walk like a wedge but don’t look like the heels from the lay 90’s. Love them and will be buying in different colors n

Great heels for beginners or comfy shoe girlies
Size: 11, Color: Nude/Clear
I am a sneaker/comfy shoe girlie. I bought these heels because it had so many great reviews. Baby!! They do not disappoint. I am 5’10 230lbs. I bought these in a size 11. This by far is the most comfortable heel I have ever worn. They are great and so comfortable to wear. Usually I bring an extra pair of flats to change into at the end of the night. No need for that with these. They are easy to walk in and they hold my weight. I love that they run a little big, I love that they have little extra space for wiggle room in the back. The only issue I had was they don’t run wide for an 11 so the toe strap was a little tight but it’s nothing a little stretching can’t help with (blow dryer and YouTube videos). Also it’s a quality shoe for a great price. Definitely will buy more in different colors.

Love these!
Size: 9, Color: Champagne-satin
I purchased these to attend a wedding as a guest. I wear a size 9 sneaker and ordered a size 9 in these. They fit well and are fairly comfortable during a quick try on and walk around. Theyre a little slick on the bottom but have a textured sole to help which i love. The color is so pretty and is true to what is pictured. I haven't worn these for an extended period of time, but feel as if they will be fairly comfortable for wedding wear. I love the chunk heel as it provides more support to walk around on. Overall great heel!
