Description
Carli has teamed up with Deaver Spring to bring you an upgraded leaf spring package that lifts the rear 1" (14-18 or 2" 19+) while drastically improving unloaded ride quality without compromising your payload capacity. These progressive springs alter the rear position sensor to ensure the air bags are deflated at the new ride height, which creates an increase in up-travel before the bags engage, providing you with a smoother ride (less air-spring ramp).
Part Number: CS-DFSP-19-D-ALAS
Features
- Designed to be used in conjunction with the Carli Ram 3500 Air Ride Specific lift system, and is NOT recommended for use in any other scenario
- Air ride specific spring kit includes sensor, bag, airtank relocation, airline, hardware, and fittings
- Provides 2" of rear lift
- Minimizes axle wrap/wheel hop
- Maintains factory payload
- Alleviates the Amp Research Step and air tank interference
- Can handle the capacity of your truck - if your airbags fail, you're not stuck on the side of the road
Notes
- ONLY for trucks equipped with rear air ride suspension
- As the weight of the truck is being held by the springs at ride height, your "ALT Trailer Height" button will not function when unloaded to drop the rear 1" for trailer hookup. This button will function normally when the truck is loaded to tow or haul at the 1" lower height, if desired, but a couple more cranks of the trailer jack handle is a small price to pay for a better unloaded ride and a safety net for your 3500

Soft and smooth cover
Color: Grey, Size: Body（20"X 54"）
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.

These are the ones you want
Color: Grey, Size: Body（20"X 54"）
May need to iron them out when wash/dried but my old ones still look new- soft, cooling, smooth, color is still great. Not itchy or cheap feeling. Buying a new set for family.

Very nice pillowcases
Color: Haze Blue, Size: 2 Pack Standard（20"X 26"）
Very pretty pillowcases. I washed them in cold water and dried them on low before using. They came out a little wrinkly but smoothed out on the pillow. The fabric is shiny and rich looking. It's not hot yet, here in Texas, but I am anticipating the coolness of these pillowcases to feel very nice. I appreciate the envelope closure. It gives it a finished look. There was no odd odor. They feel good like they'll last for a long time. I am a satisfied customer.

Body pillow covers
Color: White, Size: Body（20"X 54"）
I ordered the body pillow covers. They fit my pillow perfectly and the fabric is smooth and silky, but I did not find them cooling.

Cooling King-Size Pillows (used on a Queen pillows to tuck the extra in)
Color: Navy Blue, Size: 2 Pack King（20"X 36"）, Color: Navy Blue, Size: 2 Pack King（20"X 36"）
🛏️ Product Review: Cooling King-Size Pillows (used on a Queen bed)
⭐ The Good
• These are king-size pillows, which I actually love on a queen bed because I can tuck the ends into the fabric.
• The fabric feels slick and cool, but you don’t slip off of it.
• They feel cold to the touch right out of the package (which is wild).
• I sleep extremely hot and even run fevers at night due to a medical condition (literally 101–102° sometimes), and these pillows still stay cool where I lay my head.
• I’ve honestly never slept this well in my life.
• For the price, you cannot beat them, and they go on sale often.
• These beat any high-end version I’ve tried.
• If you sleep normal-temp and not lava-hot like me, you’re going to be VERY comfortable with these.
⚠️ The Bad
• The fabric does show crease lines.
• If wrinkles bother you, this might annoy you (doesn’t bother me personally).
🔧 What I’d Change / Tips for Care
• Don’t use fabric softener — it clogs the cooling fabric and ruins how it works.
• Wash with unscented detergent + a little vinegar.
• Dry on low heat only (do NOT dry on high if you want the fabric to keep working long-term).
✅ Final Thoughts
I will literally never not own these again.
If you sleep hot, night-sweat, or just want a pillow that actually stays cool — these are it.
10/10 recommend.
