Titainium w/7deg. Lock Seat. 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. Finally, each retainer is serialized for your protection, including valuable information, like material batch specifics as well as production and inspection dates. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. During development, each valvetrain component is tested both on the dyno and the road, including 11,000 rpm drag racing engines and 17,000 rpm superbikes. Manufactured from the best materials available, Skunk2 valvetrain components provide exceptional performance, reliability, and quality and remain standard-issue on each Skunk2 vehicle that we build and support.

Although retainers may appear easy to make, they remain a critical engine component where quality control is crucial. Material flaws and improper machining can result in incorrect valve spring installed heights and potential retainer failures. Skunk2 cautions enthusiasts from using retainers made from companies that claim to have engineering capabilities but do not have practical engine building, CAD modeling, and machining experience.

Great
Size: Large, Color: 5 Pack
These are big deal toys for our dogs. Use them when have to go out for a whole day. Have bought three sets over about two years. Takes them a several days to gut and get to the squeaker. They keep the skin around for months if we let them.

Dogs love them!
Size: Large, Color: 5 Pack
May dogs loved these. The squeaks last long enough but get lots of wear and tear. Worth money for the fun. My dog is 12 and still enjoys perfect size, weight, and flexibility.

GREAT Value even for a big boy.
Size: Large, Color: 5 Pack
My new 80lb husky/lab rescue LOVED his birthday present. They crinkle has he plays air-fetch w/himself! He does instantly puncture the squeekies at either end, but he's a large dog who chews. And these are SAFE for that. I figure 5 will last 2 months, but for the price? Who cares! He's worth it! Next time I'll go brighter colors because he tosses far &wide.

Squeaker short-lived, enjoyment long-lasting
Size: Large, Color: 5 Pack
My 10-pound dorkie rips out the squeakers in about 30 minutes. I wish they were sturdier or the parts of the toy housing the squeaker were reinforced. However, he is so excited to get a new one and will continue to play with it even when the squeaker is out. He loves to play tug. They do get pretty gross from the chewing and definitely benefit from a trip through the washer. While this is not a very sturdy toy it provides so much entertainment I had to give it four stars.
