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.

my puppy shreds every "indestructible" toy I give to her instantly. she's had one for months and it is only missing a corner of it, so I bought a spare. it also smells like food. she loves it.

Great toy!
Color: Grass Green, Size: Medium
We have a boxer and pit mix and he destroys everything. This toy however lasted the longest. He played with this every day and he plays very rough. But after 3 months I finally threw it out. It was still in tact but it was about to start falling apart. I will definitely buy another one.

Great for aggressive chewers!
Color: Mixed, Size: Medium
My dachshund pit mix is VERY hard on toys. She is a very aggressive chewer. She loves this toy and so far hasn't destroyed it! I was concerned because the center is softer, but because of the shape she is unable to get a good grip on it to chew it to pieces. Very happy with it so far!
