Valve springs are one of the most critical and overlooked components in your engine. Proper selection of the valve springs begins with identifying the application then selecting all the necessary componentry that will complement the springs in order for the engine to reach its full potential. Unfavourable results will ensue when installing a cam that will have an 8000rpm limit with the incorrect springs and supporting parts. Improper selection of the valve springs is one of the most common causes of engine failure.

One of the biggest valve spring manufacturers in the States, a specific array of valve spring kits has been developed to work in conjunction with the latest range of next gen GM LS camshafts and all other aftermarket cams in the industry. Each kit is tailored for use with specific camshaft grinds and is available in a beehive, conical or cylindrical dual spring style setup.

Each kit is equipped with everything required to upgrade your valve-train when installing an aftermarket camshaft. All components are manufactured from high quality materials to ensure durability, and performance is maintained even in the harshest environment.

No show but stays on
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.

Post-COVID Sock Hunt: Finally a Win
Size: Medium, Color: (001) Black / Black / White
Ever since COVID, I haven’t been able to find a pair of socks that hold up for more than a few months. Brands like UA, Adidas, and others seem to have cut corners—likely in response to inflation—by downgrading materials and labor rather than raising prices. The result? Socks that wear thin, rip easily, or lose shape fast. These, however, have been a pleasant surprise. I’ve been wearing them for a few weeks and so far, they’re holding strong. You can tell some cost-saving measures were still made—certain areas feel slightly thinner—but overall, the construction is solid. A key win: they stay on. These are ankle socks (not “no-shows”), and they hug the ankle securely. That’s a huge plus in a world where most post-COVID no-shows slide off halfway through the day. We may never get back to the pre-COVID quality standards without paying a premium, but for now, these are a reliable choice. Ratings: • No slipping: 10/10 • Price: 7/10 • Durability (so far): No pilling or loose threads — promising start.

Great Quality and Stylish
Size: Large, Color: (001) Black / Black / White
Exactly what I was looking for. I don’t like socks that are no-show that your ankles rub on the shoe. These are taller than that but shorter than socks that go up and over the ankle. They’re comfortable, good quality, and pretty thick. They’re form fitting m, but not compression. I dint like compression socks, and these are tight, but not too tight.
