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.

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.

Not too thick and durable and sturdy.
Color: Rustic Brown, Size: 24"W x 6.7"D, 3 Pack
Just before I purchased these 3 I bought 2 sets of 2 larger ones. The color is exactly what I was needing. They are packaged together so no scratches or damage. My husband (the installer) says they are easy enough to install. They are perfect for a diy update, durable and hold plenty of weight for their size. Happy happy customer

Good quality for the price
Color: Black, Size: 30"W x 6.7"D, 3 Pack, Color: Black, Size: 30"W x 6.7"D, 3 Pack
Seamless floating shelves that look and feel great. I opted to use different drywall anchors since I didn't trust the ones that came with the product. I have bad drywall and no studs where I was mounting so that doesn't fall back onto the product. The shelves are true to size and have held up great. The shelves themselves aren't too heavy so it leaves some room to add weight onto them. I used the 30in long shelf on the left and 24in long shelf on the right to create a nice corner shelf. There are additional screws on the bottom the keep the shelves from moving off the bracket.
