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.

Feels good on the skin not greasy
Size: 1.3 Fl Oz (Pack of 1)
Very nice product very concentrated has a very light fragrance that dissipates very quickly not greasy. No I do not have any redness or sensitivity I wanted to try this product anyway because I'm always looking for moderately priced good quality that travels well. And this fit the bill especially with it being on sale.

Good product , but
Size: 1.3 Fl Oz (Pack of 1), Size: 1.3 Fl Oz (Pack of 1)
It seems to be a good product and it’s not too heavy , but still caused few breakouts here and there . Also, Avenue always has protective foil on their cream , this one didn’t have (I replaced it but new one also didn’t have it). Also, it goes away really fast because it’s only 1.3 ounces.

Gold Star
Size: 1.3 Fl Oz (Pack of 1)
This cream is truly gentle and healing for a compromised skin barrier. I prefer this cream in the winter, when the weather is dry, and after procedures like microneedling or laser. It has never irritated my skin, and does soothe and heal. The La Roche Posay cicalfate cream is also excellent, I think it is slightly less rich, so I prefer that in humidity or the summer.
