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.

Our very favorite Christmas book
Format: Hardcover
Absolutely beautiful illustrations. A lovely, sweet, well written story that we literally never tire of. I bought this book for my daughter when she was 5 & she is 7 now. We read this book year round - it is so feel good. Edited 1.5 years later - We still love this book. Never a month passes without reading Dasher, rarely a week. My daughter owns nearly 600 books. She read 40 *new* books in August alone, so we do a whole lot of reading in this house. And we still, time and again, come back to Dasher. We love this book so much that I'm back today to order a copy for a friend's granddaughter. While here to place that order I noticed all the negative reviews and felt the need to address them. I am absolutely astonished at how many people can create something to be offended about where there is nothing. Yes, Dasher & her family start the story in a travelling circus. There are zero descriptions of animal cruelty. There is absolutely nothing dark or scary. My daughter has been homeschooled her entire life & is beyond sheltered. She is gifted-intense, which comes with super emotional sensitivity & big, big feelings. Not only does Dasher not frighten or upset her, it is one of my top go-to books to help soothe her when she is upset about something. As for the ending being confusing, that is hog wash. There is nothing choppy or unclear or confusing in the story. Apparently there are more Grinches running amok in the world than I realized!

The artwork is beautiful
Format: Hardcover
Such a sweet story with beautiful artwork! It is a little on the longer side so may not be good for younger kids with short attention spans
