Synergy MFG Jeep JL Multi-Rate Front 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, Synergy 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.

Springs are designed to be used with up to .75 inch of front spring spacer without requiring additional bump stop spacing. Multi-rate design has a softer 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
  • Ground and closed lower spring ends to prevent bowing
  • Includes front lower coil spring isolators to match the ground and closed spring ends
  • 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 Boy Loves His Freezer Toy
Style: Large - Red
The GoSports Pets PupCream Freezable Dog Bone Toy is seriously one of the best purchases I’ve made for my pup! He goes crazy for it every time I pull it out of the freezer. It’s adorable, but more importantly—it keeps him cool, busy, and happy. He loves to chew, and this toy is perfect for that. The material is soft enough for his teeth but still holds up really well. It stays cold for a while, which is great for hot days or when he just needs to chill out. It also helped a lot during his teething stage! Why we give it 5 stars: • Freezable for cooling relief and long playtime • Great for teething and heavy chewers • Easy to clean and reuse • Durable but gentle on teeth and gums Highly recommend this for any dog parent—especially if your pup loves chew toys and needs help staying cool. My boy is obsessed, and I love seeing how much joy it brings him!

Best for small-medium sized dogs
Style: Large - Red
For the price I bought two, one for each dog. I like the idea of this. In practice its not nearly deep as it should be. My dogs love it and spend 10, maybe 15 minutes, working to eat the inside once its frozen. I like the idea I just wish it was deeper than it is. Otherwise its great. Probably better for small-medium sized dogs. I have a 45 pound dog and 65 pound dog and its almost too small for them. Fun snack. The dogs love it. Easy to use and clean.

Great buy! My dogs love them!
Style: Large - Red
My 2 chocolate labs, both males, aged 7 & 8 love these. I've mixed banana and peanut butter, plain yogurt and topped with a few blueberries on top. Freeze them for a few hours and they LOVE them. I ended up purchasing 3 more - 1 as a gift for another dog's birthday party! I recommend these for all dogs 👍

Not durable
Style: Large - Red
I have trouble finding good chew toys for my dog becs there is a problem with everything. Rawhide is dangerous, bully sticks can cause infections, etc. I devised a system where I mix my dog's regular dry food with water, run it through the blender, and freeze it. I have a few bone molds where you can take the ice out fully, which work much better. I thought this would be good for him to lick. Unfortunately, once he was done licking, he began to chew the edges of the bone on this toy, and he was able to EAT little pieces off. I have a 23 lb. Cavalier King Charles Spaniel, so he's not exactly a rough and tumble kind of dog. I noticed little red flakes in his poop, so this went in the trash.
