More Info:
True conical valve springs are not a new concept and are industry proven to provide several key advantages over traditional spring designs. A major advantage of conical springs vs. traditional cylindrical or beehive springs is the damping and removal of valvetrain harmonics.
Of the three designs, conical springs are the front runners in valvetrain harmonic stability. Utilizing a varying coil diameter as well as coil spacing, a conical spring acts as a natural harmonic damper in the transfer of valvetrain shock. This translates to less stress, less wear, and a longer life of the included components.
This level of protection is needed in today’s engines being pushed to their physical and mechanical limits by aftermarket modifications. Every GSC conical spring offers a super finished surface treatment to go along with the patented, multi-step heat treatment process. The finished product is an extremely reliable, high-performance spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures.

Luxe and cozy
Color: Camel (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
Very luxurious, plush, and heavy! I bought this blanket as a gift to myself because, being cold natured, I LOVE to have plenty of throws/blankets around the house. This one stays on my bed and was wonderful this winter. My cats love it, too!

"Cozy & Chic: The Perfect Cow Print Faux Fur Throw Blanket!"
Color: Black Ombre White (Faux Fur Bubble + Flannel), Size: Twin (60" x 80")
I recently purchased the cow print faux fur throw blanket, and it has quickly become one of my favorite home accessories! This throw is absolutely beautiful and adds a stylish touch to my couch.
Not only is it visually appealing, but it is also incredibly soft and cozy. I find myself wanting to curl up with it on the couch and even take it to bed with me! The quality is outstanding, and it feels luxurious against the skin.
Whether I'm watching TV or reading a book, this throw is the perfect companion. It's both practical and decorative, making it a fantastic addition to any home. Highly recommend it for anyone looking for a warm, stylish blanket!

Wrapped in luxury
Color: Cream (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
I went through a lot of faux fur throws and blankets to find this gem. It’s double sided fur and very warm and cozy. My only gripe is that it’s not wider but it measures true to its size. It’s super soft and fluffy. Would highly recommend this blanket as you’ll be wrapped in luxury.

Amazing and luxurious
Color: Cream (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
My daughter said this blanket can be described as luxury. It is soft, plush, and warm. It does slip and slide some, so just be aware that it can do that
