Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kit for Honda's B-series VTEC engines. Each kit includes Skunk2's high-quality dual valve springs and race-proven titanium retainers that are the result of nearly two decades of racing and engine building experience. Each Alpha Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm. Skunk2's industry-leading Alpha Titanium Retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Similar to Skunk2's already popular Pro Series Titanium Retainers, Alpha Titanium Retainers feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction. Alpha Titanium Retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno as well as the race track. Once approved for manufacturing, only medical-grade titanium that's been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures.

Wrong size on shirt’s tag and description!
Size: 16"-16.5" Neck 36"-37" Sleeve, Color: Dark Blue, Size: 16"-16.5" Neck 36"-37" Sleeve, Color: Dark Blue
We have ordered Van Heusen dress shirts in size 16.5 neck and 36”-37” sleeves for years. This shirt’s sleeves are 2-3” too short! The shirt is tagged wrong. I ordered the same size brand and shirt in a different color and you can see the difference in the sleeve’s length in the photo! Annoyed I need to return the defective item.

Excellent shirt that compares to box brand stores and fits very well.
Size: 15"-15.5" Neck 34"-35" Sleeve, Color: Light Blue
I recently lost 44 pounds and all of my dress shirts no longer fit correctly. These are an excellent replacement. I am 6'2" and now 180 lbs. These are a perfect fit and are slim where they need to be and don't bunch up on the sides, and they are super comfy. Bottom of the shirt is long enough to keep tucked in even when bending over. Sleeve length is decent, they do slide up past my wrists when doing extreme reaches, but are right at the hand/wrist connector when in an idle pose. They did have a weird chemical smell when I first put them on, but let them air out when you first put them on. They are also very wrinkled, so make sure you have an iron around. No status on durability, but the material is not super thin, its thick like Target shirts.
