Lift your 2011-2019 GM Silverado/Sierra 2500HD/3500 6.6L Duramax LML/L5P 4WD properly with the Icon K78103 0-2" Stage 3 Suspension System from GAP. The 2011-2019 GM 2500HD/3500HD requires significant shock damping to comply with the massive spring rate of the factory torsion bar system. Icon Vehicle Dynamics has developed a range of suspension systems with optimized vehicle specific shock damping. These systems offer excellent on and off-road drivability. While driving the construction site or trails to your favorite dirt bike location, Icon wants you to get there in comfort just like your drive to work. The Stage 3 system is comprised of our V.S. 2.5 Aluminum Series front & rear reservoir shocks featuring Icon's Compression Damping Control Valve (CDCV) for 10 settings of adjustability for any driving style or condition. The Icon vehicle specific tuned 2.5" diameter shocks with CDCV are the key to attaining optimum ride quality and getting that desired comfort with the 3/4- & 1-ton working capability. Adjustable reservoir shocks ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. Additionally, Icon upper control arms add strength, durability, and when paired with extended travel shocks increases wheel travel 2" over the OEM configuration.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉

Stretchy Material and Cooling Fabric
Color: Light Gray, Size: Standard, Color: Light Gray, Size: Standard
Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case. Durability: zipper works great and material is easy to clean. Color: I have the gray and my daughter has the pink. Both colors as advertised. Value: Good value and I got what I expected.
