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.

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.

Cute for girl's dorm room! Needs a wash/dry warning.
Color: Pastel Lilac, Size: Twin/Twin XL
Wash/dry by itself. Leaves lint on anything and everything that is washed and dried with it. Kiddo learned the hard way. Loves the blanket and it's feel and color but was disappointed with the left-over pills on the rest of her items from that 1 load. Soft, fluffy and lavender. Great for her dorm!

I almost didn't purchase because I was nervous about the shedding. To my surprise the quality is fantastic. Minimal shedding and soooo soft! The size is perfect for a TON of stuffed animals along with blankets. Good bang for your buck!! Makes organization a breeze!! It is very durable when needing to move!

Too expensive to rip within hours
Color: Leopard Print Brown, Size: Large(38"x38"x40")
The handle ripped off while carrying, which left a giant hole on the top. The beanbag was in no way overstuffed or heavy. Not worth the money.
