Synergy MFG Jeep JL Multi-Rate Rear Lift Coil Springs. 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.

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.

Benefits:

  • Increased ride quality
  • Increased wheel travel/articulation/traction
  • No spring bowing
  • Lifetime warranty/guarantee against sagging and breakage

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 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

Notes:

  • 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.

Great value, great quality.
Color: Black/Black/ Black Digital
My husband bought this watch for work. He can’t have his phone on him at work so this watch has been very useful for him. He sweats a lot and works in a warehouse. He has a nicer “church” watch I bought him as a wedding gift and he actually has started to prefer this one. There are only two little annoyances (which might be able to be fixed) every hour the clock beeps and that the alarm goes off every morning including weekends. Those things might be features which some desire and some that even we are impressed by so 🤷🏻‍♀️ as I said, those minor issues might be fixed if we look into them but my husband doesn’t find them as bothersome as I do and he’s the one who wears it.

Would definitely recommend this watch.
Color: Black/Black/ Wjite Digital
Nice manly watch. Many Timex watches are too small. I love the size of this one and yet it's still lightweight. The face of the watch is neatly organized and very clear to read. Indiglo light works well at night. Only thing I see missing from this watch is a countdown timer. It has a stopwatch.

Big face, easy to read Timex quality at superior price
Color: Black/Black/ Wjite Digital
Great watch at amazing price. Better looking and much cheaper than current timex ironman models. Large face and numbers = easy to read. Has alarm and stopwatch functionality. Intuitive interface.
