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.

Amazing Spark plugs
Smooth starting came after I fitted these Bosch 9614 double iridium plugs into my 2014 Honda Accord Sport, along with slightly better idling behavior. Longevity might come from those fine iridium tips; installing them felt straightforward enough. Yet here's the catch - the 9614 doesn't match what the factory actually specifies for the 2.4L engine in that year’s Accord. Most often, it's the 9694 or some other OEM-recommended plug you’d want instead

Great plug
Not sure about gas mileage, but these definitely improved the performance of my little 1.8 L Honda Civic, not sure if it’s because the old Plex were just old and weak or just because these are that much better. Acceleration is much better and engine or idle is much smoother

Bosch is a good product in any form
I had used these plugs before in my 03 Honda Element and they performed well for 5 years or more so I considered these for use in my now 07 Honda CRV.
