Grab the Synergy 8864-30 3"-4" Rear Lift Coil Springs from GAP for your 2018-2023 Jeep Wrangler JL. Synergy MFG has designed these springs from a clean sheet for the new Wrangler platform. All springs are multi-rate and have been designed to make a great platform even better. These springs are unique to the JL and not shared with the JK or other vehicles. Like OEM, our coil springs are unique lengths to account for load differences on each corner of the vehicle. There are right and left specific springs front and rear to guarantee the vehicle will sit level. The multi-rate design has a soft initial rate which prevents the spring from coming loose in the coil tower, even with long travel shocks. The ride rate is slightly stiffer than the OEM springs to account for additional weight from bumpers, winches, skid plates and gear. 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 Only 5-10 Percent Stiffer Than Stock For Superior Ride Quality
- Coil Spring Block Heights Are Designed Around Common Bump Stop Spacings To Optimize Wheel Travel
- Unique Spring Lengths For Each Corner Of The Vehicle So It Will Sit Level Side To Side
- 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: 4-Door Lift Height: 3"
2-Door Lift Height: 4"
Coil springs require proper bump stop spacing with Synergy 8057-10 Bump Stop Spacers.
Lift heights are based off fully loaded 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.
Min 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.

Longer Lasting than most things I've tried
Size: 1 Count (Pack of 16)
I bought these to go on the PetSafe Bouncy Bone which I had bought for my Australian Shepherd/Vizsla mix puppy who chews everything. We had gone through so many "long-lasting" chew toys/bones that really lasted only about 10 minutes and I was looking for something to occupy his time a little longer. These do the trick. Although they still don't last super long, they take a little more effort and keep him distracted a bit longer than anything else edible that I've tried. To me they are a bit pricey, so I try to make them last by only putting one on at a time, instead of one on each end of the toy. I also tighten the ends pretty tight to make it more difficult for him to get at the entire ring. If you don't mind the price, these are an easy and convenient way to keep your dog busy.

PetSafe Busy Buddy Refill Ring Dog Treats
Size: 1 Count (Pack of 16)
Great! My Baby Pearl Anne loves them. And, she won't normally play with anything else. The Vet says it's due her being in a HORRIBLE Puppy Mill. She never had a puppyhood. She is still Neurotic, even after having been her parent for over 4 years. I would definitely like to get my hands on these people, if I knew who they were. She was found her on a VERY busy intersection way up north in the Texas town where I live.
I don't normally go in this neighborhood, so I didn't see her on the street. My best friend, who died just 4 years ago on the 18th of March, had a ex coworker. Leslie(my best friend),KNEW I wanted a dog. I fell in love with her dog: a Miniature Schnauzer. One day Leslie's coworker called her. She said they had found a dog on the street. The coworker said that she couldn't keep anymore dogs. She has 3. So, when they described her, I knew I wanted her! She's a rare pure white Miniature Schnauzer. She was skinny, shaking, with horribly matted hair. She was scared to death, and freezing to death. I put her in a towel, and took her the Vet. And, she said she had worms, was dehydrated, and malnourished. not anymore. She's my baby, my child. Who is now spoiled to death.
Sorry this is so long, but, I really needed to tell her story.
Donna Valentine-Jones.
