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.

Pups all time FAVORITE!
Color: Dim Sum Dumpling Pet Toy Set
Our pups FAVORITE “ball”. He’s obsessed and has a blast with these little dumplings. Small size toy, but our medium labradoodle loooves them. Not to loud of an squaek either. They last quite awhile before he pops the squeaker. Fabric holds up really well.

Great squeaky fetch toy for small dogs
Color: Dim Sum Dumpling Pet Toy Set
My dog loves these little squeaky dumpling toys. They are the right size for small dogs (under 20 pounds) to chase and fetch, and they have good squeakers inside. They have a friendly look and my dog can fit them in her mouth.

Cute toy for small dogs!
Color: Pinata Dog Toy
My dog is obsessed with this toy. This does not have a squeaker in it which is great cuz she doesnt like them. The crinkles and rope seem very durable. She did eat the tail very quickly but overall its held up well! Great tug toy for a small dog or puppy!
