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.

Little big
Size: 20, Color: Rinse Wash
They run just a tiny bit big. The length is more ankle length instead of capri length as shown. However, I liked the wash and the length doesn't bother me. Perfect match to the essentials jacket.

good stretch
Size: 10 Long, Color: Dark Wash
Honestly, these are one of those surprisingly good basics—especially for the price. The biggest standout is the stretch. They’re really comfortable and move with you, so they don’t have that stiff “jeans” feeling. They hug your body in a flattering way without feeling too tight or restrictive, which makes them easy to wear all day. The mid-rise fit is also a sweet spot—not too low, not too high—so they’re super versatile with different tops. What I liked: Very stretchy and comfortable (almost feels like jeggings, but still looks like denim) Flattering skinny fit through the legs Easy everyday jeans—work, errands, going out Great value for the price What to know: Material is on the thinner side (more comfort than “structured denim”) They can lose shape slightly after a full day of wear Not the most durable long-term compared to higher-end denim Final thoughts: These are perfect if you want cute, comfortable, affordable jeans you can throw on with anything. Not premium denim, but for everyday wear—they definitely get the job done and are worth having in your rotation.
