Replace the coil springs on your 2018-2023 Jeep Wrangler JL or 2020-2023 Jeep Gladiator JT with the Synergy 8863-40 4"-5" Front Lift Coil Springs from GAP. 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, Synergy 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. Springs are designed to be used with up to .75 inch of front spring spacer without requiring additional bump stop spacing. The multi-rate design has a softer 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
- Ground And Closed Lower Spring Ends To Prevent Bowing
- Includes Front Lower Coil Spring Isolators To Match The Ground And Closed Spring Ends
- 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
Note: 4-Door Lift Height: 4"
2-Door Lift Height: 5"
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.

Good So Far
Color: 01 - White, Size: Queen (2 Pillowcases)
Don't let my 4-star review dissuade you, as I've had to reassess prior products that initially I thought were great but then failed me in the long term. These are definitely full and plush, you might want to avoid if you prefer slightly thinner support, especially if you are a side sleeper. But so far I find them comfortable and meeting all of my expectations.

These Made My Bed Game Stronger
Color: 01 - White, Size: Queen (2 Pillowcases)
These pillowcases impressed me right away. The material feels good in your hands and the stitching looks like it was done right. Soft enough to sleep on comfortably, but not that overly silky soft that gets hot.
I’ve washed them several times already and they came out looking the same each time. No shrinkage and no issues with the fit.
I sleep pretty still, and honestly I never even think about the pillowcases once I’m out. That tells me everything I need to know. Great value and something I’d buy again.
