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.

Perfect fit every time
Color: Silver, Size: 30W x 30L
These original 874’s are the real deal. Stocked up during the sale and got them for my husband. He loves all the colors and the durability of these pants is incredible. He still has some from 14 years ago! But he wanted a few new ones- and they had more colors so I stocked up and surprised him when I told him how much they cost during the sale. These pants never wrinkle. I wash them hot and air dry- no wrinkling or shrinking. They look great. They’re sewn to perfection. The quality is there and has been for years, a reason my husband only wears these. Quality, value, durability, style, fit. Great for all seasons, they’re not too heavy or too light. Great functionality- pockets for everything . Great even in summer - they are very breathable. Perfect fit every time. Great for heavy road construction or just going for a hike. Highly recommend!

Run small, size it up
Color: Mushroom, Size: 32W x 30L, Color: Mushroom, Size: 32W x 30L
They go small, Im 5'8", 165lbs, usually 32x30 fits just rigth in most brands Levis, Izod, whatever, can't even close the zipper on this one, my dingus prints in the front if I manage to close it, I will try a 34 or even 36, if you want one, size it up. Length is right. Anyway, the pant is good, sturdy looking material, is not soft but nothing uncomfortable probably gets right after break it in, reinforced stitches on pockets. I think they would work great for a technician, salesman or an engineer, those jobs where you have to look like a human being with a polo shirt but sometimes needs to do something without ripping your pants while crouching or for daily abuse of the regular Joe, will try another that fits
