Tweak your boost levels with this GripTec "upper" pulley upgrade for your 2.3L LS9 blower. The stock LS9 blower came on C6 Corvette ZR1s and this bolt-on upgrade allows you to change the spin-rate of the ZR1's supercharger. A Griptec upper pulley upgrade is a cheap and effective way to boost power.

ZPE (the company behind the GripTec pulley system) has their own mounting "hub" (the ZPE hub) that's required to use this LS9 pulley. If you already have the ZPE hub you can simply buy a pulley by itself. Otherwise you can buy a pulley and hub combo or you can buy a hub separately. The hub comes with a set of 10 titanium screws for weight savings and strength.

The GripTec pulleys are made from billet 7075-T6 aerospace grade aluminum which is Stronger and harder than 6061-T6. What makes these Corvette ZR1 (C6) pulleys really shine is the "GripTec" technology that's applied during the machining process.

GripTec is a micro-machining technology that allows for maximum grip force to be applied to the ZR1's supercharger pulley without damaging your blower belt. More importantly the GripTec technology essentially deletes belt slip on the LS9 blower allowing all of the crank's power to be transferred to your blower via the pulley.

GripTec Level: V2 (Coated)
Hub: ZPE (10 Bolt M5)
Ribs: 11
Color: Black
Finish: Type III Anodized, Class 2, Hard Coat

Comfy soft pillow covers
Color: 02 - White, Size: Queen (20" X 30"), Color: 02 - White, Size: Queen (20" X 30")
Absolutely love these pillow cases! I bought 2 sets. After I received them & washed & dried them they did remain wrinkly. I just went ahead and put them on my pillows & the wrinkles went away. I continue to love the feel, coolness & comfort. Will definitely buy more.

Pillow cases are beautiful and soft, great quality. I had to return them because standard were too small. I am going to order queen instead.

These Bamboo Pillowcases Made Me Realize I Sleep Hot
Color: 07 - Cream, Size: Queen (20" X 30"), Color: 07 - Cream, Size: Queen (20" X 30")
I bought these mostly because I kept hearing people talk about bamboo pillowcases and honestly thought it sounded a little overhyped, but I totally get it now. The first thing I noticed was how cool they felt compared to regular cotton. I tend to get warm when I sleep and flip my pillow a million times during the night looking for the cold side, and these actually stay noticeably cooler longer. They also feel really soft without having that weird slippery texture some silky pillowcases have. My skin has been less irritated lately and my hair definitely looks less frizzy in the mornings. I have thick hair that tangles easily overnight, and these have helped more than I expected. Another thing I appreciate is that they’ve washed well so far. I was worried they’d pill or lose softness after a wash cycle, but they still feel smooth and nice. They also just make the bed feel cleaner and more comfortable overall. One of those small upgrades that ends up making a bigger difference than you’d think.

Sheets are good. Greens don't match
Color: 08 - Sage Green, Size: King (20" X 36"), Color: 08 - Sage Green, Size: King (20" X 36")
I purchased the sage green sheets to go along with another Bedsure comforter, then purchased 2 more pillow cases (because i I like a lot of pillows) and the greens don't exactly match. This doesn't REALLY bother me as I feel like its fine with a little "texture." Sheets feel nice and light and I love the look of it in my room.
