Upgrade the coil springs in your 2020-2023 Jeep Gladiator JT with the Synergy 8865-30 3" Rear Lift Springs from GAP. Synergy has designed these springs from a clean sheet for the new Gladiator platform. All springs are multi-rate and have been designed to make a great platform even better. These springs are unique to the JT and not shared with any other vehicles. The multi-rate design has a soft initial rate which prevents the spring from coming loose, even with long travel shocks. The ride rate is the average of the OEM spring rates to maintain adequate payload and towing capacity. Springs are proudly manufactured in the United States of the highest quality steel. Springs are designed to be able to set solid (fully collapse) without overstressing the material and are pre-set from the factory meaning the springs will never sag or set.
Features:
- Multi-Rate Coil Springs Allow For Longer Spring Lengths And Increased Travel
- Spring Rates Are Similar To Stock To Maintain Payload And Towing Capacity
- Coil Spring Block Heights Designed Around Common Bump Stop Spacings To Optimize Wheel Travel
- Frequency Balanced And Tuned Spring Rates To Maximize Suspension Performance On And Off Road
- Abrasion-Resistant Black Powder Coat Finish For Maximum Durability And Corrosion Resistance
- Sold In Pairs
Note: Coil springs require proper bump stop spacing with Synergy 8057-10 Bump Stop Spacers.
Lift heights are based off fully optioned Rubicon models. Other models will see more lift.
Coil springs retain the stock rake of the vehicle.
Up to .75 inch of front coil spring spacer can be added to level the vehicle using 8017-075 front coil spring spacers.
Minimum bump stop spacing listed is the minimum amount of bump stop spacing required to prevent the springs from going into coil bind. Do not use less bump stop spacing.

I am stunned
Color: Black, Size: Queen(20x30)
I had no idea what to expect from these. But for as cheap as they were I was willing to just write it off of they weren't that good.
I had already picked up a new memory foam pillow to replace my previous memory foam pillow that didn't do well with dissipating heat. This new pillow was fine by itself, but when I put my pillowcase on it, the properties that made it cooling were negated. I'd get a bit of sweat on the side of my head or my neck where it was against the pillow all night. The pillow was supposed to be a cool one, but the pillowcase was not.
So I grabbed this set. Smooth, no loose threads anywhere, stitching and seams are all spot on. And it's smooth to the touch. Got it on the pillow, and as soon as I laid my head down on it, I could tell immediately that this was going to be a different result that my other one. Not nearly as warm even after laying on it for a while. No heat buildup, no bits of moisture on the skin after being on it all night.
This definitely works well, especially with my cool sleep pillow. Now I can have a far more comfortable nights sleep. For the price, it's a steal. I have no idea what longevity will be, but with two of them, I'm sure I'll get more than my money's worth.

Soft and cooling
Color: Dark Grey, Size: 2 Pack Queen(20x30)-Regular
Soft, not too thick and wash very well. Feels great against my skin and doesn’t make my hair frizzy. Color was perfect.

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!
