Quick Fuel Black Diamond SS-Series Carburetors
These Quick Fuel Black Diamond SS-Series carburetors are designed to offer the power of a race carburetor in a streetable package that weighs 5 lbs. less than other carburetors. They feature a unique PTFE Teflon coating that provides a highly durable satin black finish, is impact and scratch-resistant, and impervious to underhood chemicals. The coating also offers a six percent reduction in fuel temperature, allowing for improved performance. Manufactured completely from aluminum, they allow you to change the idle feed and offer power valve channel restrictions and idle and high-speed air bleeds for the ultimate in tunability. The solid-state, electric-choke Quick Fuel SS-Series carburetors have billet throttle bodies, billet metering blocks, 4-corner idle systems, secondary jet extensions, and notched secondary floats. The vacuum secondary carburetors feature fuel bowls with a single-sight glass window, while the mechanical secondary carburetors have dual-inlet, dual-sight glass 4500-style fuel bowls and include additional links to tune the secondary opening rate. Quick Fuel has done it--they've created an all-aluminum Super Street carburetor that's perfect for your high performance street machine.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

Healed cracked feet!
Color: Gray
These moisturizing heel socks are great for dry, cracked heels. They’re soft, comfortable, and easy to wear around the house or overnight. I like that the silicone/gel part helps lock in moisture, especially when paired with foot cream or lotion.
They fit well without feeling too tight, and having 4 pairs is really convenient. After using them consistently, my heels felt softer and smoother. Great little self-care item, especially if you’re on your feet a lot or struggle with dry skin.

Great stretch.
Color: Gray
My husband has diabetes and these work great on his heels.
I was worried they would be too small, he wears a size 12 shoe and they fit great!
