Add a Synergy 8840-2000 2" Starter Lift Kit Suspension System from GAP and upgrade your 2018-2023 Jeep Wrangler JL (4 Door). 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 vehicle and include all necessary components for the lift height and performance advertised. All of these systems have shock solutions available, whether it be shock relocation brackets to continue using the stock shocks in our Starter System or one of our Synergy MFG tuned shock packages aimed at affordability or performance. Coil springs and shocks are two of the largest determining factors in ride quality and a mismatched system will never perform to its potential. All Synergy MFG tuned shocks are matched to the coil springs and application to provide the best ride and performance possible.
The Jeep JL / JLU Starter System is a coil spring 2" lift designed around 37" tires for Rubicon models and 35" tires for non-Rubicon models (See fender and bump stop spacing recommendations below). This system is designed to be the most capable performance coil spring lift on a budget, with room to upgrade as funds allow. For more complete 2" lift systems, see the Stage 1 or Stage 2 systems.

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:
In Order to use factory shocks you need to add Part Number 8819 to the KitIf using longer travel aftermarket Shocks you have to do one of the following options:-
1) Move OEM rear sway bar links to the front and add 8860-11 to the rear
2) Keep OEM rear sway bar links and add sway bar disconnects to the front
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).
For off road use, the front sway bar can be disconnected on Rubicon vehicles via the built in electronic disconnect system. On non-Rubicon vehicles, Synergy recommends the addition of their front sway bar disconnect kit, 8859-01.
Synergy MFG's Starter System is designed to be used with stock length shocks. If upgrading to longer shocks, the suspension will also need to be upgraded to at least Stage 1.

Synergy MFG 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.

Wonderful teething toys for small teeth!
We bought these for our new three chihuahua babes and they love them so much! For now, since the babies still get really cold, we just do them as is and are going to hold off on freezing them for a bit but it's still great! They love to chew on either end and the different textures of both the rag and the different ones on the bone itself, keep them really entertained.

Gumby is a hit!
Size: 9 inches - Plush Gumby, Size: 9 inches - Plush Gumby
The dogs LOVE their Gumby toys! Do I expect them to last long? Not with this dog. In fact, the dog pictured began chewing Gumby's arm off shortly after this photo and had to be redirected, given a chew, and the Amazon box to shred before trying Gumby again. However, if your dog is like my Boston and more gentle on soft toys then this toy will last a long time. Her Gumby remains fully intact and loved. So, if you're buying this, just know your dog's style of play and how they treat soft toys, then purchase with reasonable expectations. I knew my wild man would destroy this, he destroys the tough made stuffies, but he has fun doing it and you can't beat the $3 price.
Overall it's a cute toy at a good price. It's fun to play fetch with it in the house, but I wouldn't tug at it. Playing tug could rip it.

GREAT for small dogs!
Size: 6 inches - Plush Gumby
My Pekingese, Yuki, has tiny and shallow jaws. So, it’s tough to find toys she can hold, let alone squeak. But “Gumby” was a surprise, and a fast favorite.
The fur is pleasantly smooth, vs. dense. It seems to help. The front/back are somewhat flattened. That seems to help, too. The squeaker is strategically placed…. Thus, she can easily mouth the neck/head area, regardless of the arm placement to easily squeak away….
And what fun to twirl. I’ll grab an arm, and spin her in circles. It’s wonderfully stitched. Nary a worry about an arm coming off.
A truly quality toy…. Purchase for your wee one with confidence!

After a good scrub, the dogs love them!
Size: 9 inches - Latex Gumby, Size: 9 inches - Latex Gumby
These gumby toys are flexible rubber, and exactly what you'd expect for the price. I ordered three to replace two that had been gifts well loved by my dogs.
I read reviews mentioning smell, but wasn't really prepared for it when the package arrived. They all arrived zip tied to a paperboard backing. They all smelled like a fine fragrance designed for robots - like burning motor oil with floral undertones - and the zip ties were stained a sickly green wherever they touched Gumby. Initially, my dogs wanted nothing to do with them, even after a good scrub. I left them to air out in the shed for a few days and then ran them through the dishwasher (without cleanser!) and they were good to go.
My dogs love these toys. I know they're not going to last long! I know the arms will get yanked or chewed off first, and then the corner of Gumby's head will go missing. Eventually, his head will be ripped into tiny pieces and strewn about my living room. I know that, sooner or later (and probably sooner!), Gumby will be little more than a torso with weird square legs. And that's okay, because that means my dogs enjoyed the toy.
People complaining about a $7 flexible rubber toy not being appropriate for heavy chewers don't understand what dogs need, or what dog toys are for. Part of the satisfaction that chewing brings for dogs is also shredding. Dogs destroy stuff. Some more than others. It's what they do. No toy will last forever if it's used! But I have five dogs, including bully breeds and a Saint Bernard, plus two occasional visitors, and these toys have lasted longer than expected (even if their arms are off in minutes!)
The dogs in the pictures are 90 and 120 pounds, modeling both a well loved older Gumby and a brand new one.
