Titainium w/7deg. Lock Seat-Must Use Skunk2 P/N: 312-05-0010 (Locks) on 05+K Series. 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.

Nice little jewelry box
Color: Cloud White, Material Type: Paper, PU
Just what I wanted in size and available compartments. The only thing I am hesitant about is the paper outside. Mine is white and may get dirty quickly.

finally organized all my jewerly!
Color: Black
This jewelry box completely transformed the way I store and access my accessories. It’s not just functional, it’s genuinely beautiful, with a sleek design that looks great on my dresser. The exterior feels sturdy and well-made, and the interior is soft and luxurious, keeping all my pieces protected and tangle-free. There’s a perfect place for everything: rings, earrings, necklaces, and even watches or bracelets. I especially love the multiple compartments and drawers, which make it easy to separate everyday items from special pieces. No more digging around or untangling chains! The mirror inside is a thoughtful touch, and the box itself feels compact enough for smaller spaces while still holding a surprising amount. It’s one of those things that makes daily routines feel a little more put-together. If you’re looking for a jewelry box that’s practical, elegant, and gift-worthy, this one checks every box. Great for personal use or as a thoughtful present.
