Elevate the suspension system on your 2018-2023 Jeep Wrangler JL (4 Door) with the Synergy 8843-4000 4" Stage 3 Lift Kit Suspension System from GAP. Synergy MFG Suspension Systems use a synergistic approach, meaning the combined effect of the components is greater than the sum of the individual parts. The overall performance of the system is the most important factor when designing components to work together. Synergy MFG Suspension Systems are complete systems for your Jeep and include all necessary components for the lift height and performance advertised. Coil springs and shocks are two of the largest determining factors in ride quality and a mismatched system will never perform to its potential.

This system is the apex of Synergy's JL Wrangler offerings and capable of extreme performance.

Wheel and Tire Fitment:
Recommended tire size is limited by fender clearance. With higher clearance fenders or trimmed fenders, larger tires may be fitted. Bump stop spacing should be matched to the collapsed length of the shocks. Mismatched bump stop spacing and shocks will limit the available travel from the system.Notes:
Synergy MFG coil springs lift the vehicle the advertised height over stock based on a fully loaded JL Rubicon. Other JL models will see more lift over stock. These coil springs do not lift taller than advertised. The stock rake based off the Rubicon model is kept to retain its load carrying capacity. If you prefer the vehicle to sit level when unloaded, Synergy recommends adding a small coil spacer to the front (up to 3/4-inch without affecting up travel or causing coil bind, 8017-075).Synergy is not responsible for maintaining finish of products. Environmental factors will affect rate of corrosion and wear for items advertised to be corrosion resistant. Synergy recommends using protective coatings for all items that will see extended outdoor and off-road use. Synergy has had great experience with the Fluid Film product and recommend it and similar products for any items susceptible to damage from corrosion. It is great for keeping double adjuster assemblies working like new and protecting shock bodies from the elements.
Additional Specifications:
Lift Height: 3-inches over stock Rubicon, 3.75-inches over stock Sport/Sahara

her eyes focused on it like laser beams and I could see the bloodlust in ...
I have bought all sorts of toys for my VIzsla, but nothing has made her more crazy than this rabbit. I have bought her stuffed mallard ducks, kong toys, fluffy sheep and all manner of hard, soft, stringy and other toy - but when I first pulled this rabbit out of the shipping box, her eyes focused on it like laser beams and I could see the bloodlust in her soul. The rabbit's head was barely clear of the cardboard box when Rosie was lunging at it. I'm tall and she had no hope of getting it, but she bounced off my thighs and made another jump in anticipation of the rabbit coming lower. She was of single purpose and nothing was going to stop her - this rabbit needed to be killed. It was hard to even throw it for her, because each time I moved my arm to swing it, she lunged for it... I had to go with the overhand throw, and she still leaped to pluck it from the air as it sailed a good three feet above her head. When it bounced along the ground, she was on it in an instant. The rabbit has squeakers in all four of its paws (and its head) and a "grunt" type of noisemaker in its body. It started grunting and squeaking at the same time as Rosie began her bloody work. I had to keep telling her to calm down so that my $15 investment would get me at least a dollar a minute of viewing pleasure watching my pooch eviscerate the thing. I managed to distract her by pointing outside and saying "whassat?!?!?" and as she looked for a moment, I snatched it from under her jaws, only to hear the crisp clack of her teeth as she made a last desperate attempt on the rabbit's ear as it vanished around the corner of the couch.
I have bought two of these rabbits. I sort of wish I had Jeff Bezos money. I would buy a hundred of them and make a ball pit for Rosie, but made from these rabbits, then I would record the results and upload it to YouTube as my submission for the definition of bliss.
I'm sure you are getting the idea... dogs go NUTS for this thing. I think it's a combination of the numerous squeakers, the type of squeakers (especially the grunty one), the crackly material in the ears, the softness of the rabbit, the coloration of the fur that looks so real and lifelife, the innocent look on this thing's face that lets dogs know they can just go full Ghenghis Khan on this thing with reckless abandon.
The only downside is it doesn't last. Not if your dog has the heart of a warrior. I am sure some day Rosie will develop some chill... now she has no chill and the Colossal RABBIT is her plaything. In the future I'll get her another and maybe she'll lay her head on it to sleep. But it sure is fun watching my little girl act like I used to when I was 8 years old and got that present I didn't think I was going to get (but hoped beyond hope I would) at christmas time. It's worth the price to see a puppy going full-puppy on this thing. Hats off to the people who designed it - it's effect on dogs is like wearing a Palpatine Imperial Guard outfit, dousing yourself in heifer pheromones and walking up to the angriest bull you can find while he's eating dinner and punching him as hard as you can in the gonads. That's how dogs react to this rabbit. It's divine.

I love it too - it is adorable and so high ...
My dog loves this thing! It is quite large (15 inch model) and it has SO MANY SQUEAKERS. There is a squeaker in each paw, one squeaker in the belly that makes a grunting sound, that crumply sounding stuff in the ears, and a squeaker in the head! My 70lb mixed breed dog usually tears apart soft stuffed toys, but he's had this one for months and hasn't even attempted it. That's not to say I don't think he could tear this apart, he simply has chosen not to for whatever reason. He just loves his bunny. I love it too - it is adorable and so high quality. If it weren't for the squeakers, I would think it was intended for a human child. This is one of those rare items I would purchase again and again, though it doesn't look like I'll have to.
UPDATE: After four months, it was ME who ripped this toy! I pulled one of the ears while my dog had it in his mouth and the seam ripped. Amazingly, my dog didn't seize upon that as an opportunity to tear it apart. Ordinarily, if one of his toys tears he goes straight for the stuffing (usually it's HIM that tears them open). I just ordered a new one - not because there's anything wrong with the first one, but because it's lasted so long that it's totally gross and now needs to live outside and I had a coupon for amazon so I figured, why not?
I still love this toy. I go to Jolly and JW Pet Company for all of my tough rubber and plastic dog toys, but for stuffies this is a perennial favorite.

Abbie Gives It Four-Paws Up !
My Flatcoat Retriever has been collecting stuffed animal friends for almost eleven years now. She never destroys them---tends to cuddle or wrestle with them. She likes to give them a good shake. She never disembowels them.
This has turned out to be one of her favorites, if not THE favorite. Not only is it much more lifelike-looking than most stuffed animals, it is life-sized. Best of all, while the paws have squeakers, if the chest cavity is compressed, it emits a low guttural sound, making it again, the most lifelike stuffed animal I have come across. It sounds like a pig feeding...like grunting, which is cool and creepy all at once.
Very sturdy. Lots of fun. You can spend less, but not for an animal that is going to get this much attention.
Great toy.

Teh awesome rabbit
Don't let this bunny fool you. It's almost too cute and fluffy, but has surprising staying power. Over the past month it has been thoroughly shaken, tossed, slobbered, pounced on, and dragged wherever, by a German Shepherd pup who has proved to be the jaws of death for many stuffed squeak toys that sport better pedigrees. The only reason I've given it four stars instead of five, is that I have had to sew its seams a number of times, like almost every night at first (sort of understandable I guess), and only two and a half of its many original squeakers still work. The fact that it still actually looks like a rabbit and those squeakers still work (and none were ever torn out) is actually a testament, when I come to think of it. Huh. Anyway, at this point it looks disreputable and bedraggled as h**, and it has lost its tail, somewhere along the way. But it is still the pup's favorite toy and best friend (she coo's to it in her throat)--bar none. And when it comes time for it to go, I'll be buying another one.
