Upgrade your 2018-2023 Jeep Wrangler JL (4 Door) with a Synergy 8840-1000 1" Starter 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 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-inch 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 our 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.

Eliminated continual bad breath and some thrush
I’ll keep this short - I’ve had oral thrush since taking antibiotics years ago. My breath was always good though so I never cared much (though I do eat probiotic-rich foods whenever I can). Lately, I started developing a gross taste in my mouth that and my wife was saying my breathe wasn’t great - not a fun thing to hear. I tried mouthwashes, general probiotics, oil of oregano, etc...nothing worked.
I bought these on a whim and began taking them just 5 days or so, my breathe is no longer bad. The thrush has minimized as well, though is still present toward my the back of my tongue. Amazing.
I don’t write reviews and wasn’t paid to do so for this product - just bought randomly, hoping it’d help, and it did. I’m sure it won’t work for everyone since everyone’s body is different, as are the reasons you might be experiencing bad breath, but for me, this is amazing.
BY THE WAY: I see reviews saying they took these like pills. That’s not going to work, you have to let them completely dissolve I. Your mouth as the instructions say!

A Lifesaver for Dry Mouth, Without That Weird Aftertaste 👏
Size: 4.3 Ounce (Pack of 1)
If you know, you know: dry mouth is not just an inconvenience, it’s downright uncomfortable. I’ve tried several brands over the years, but Biotène is the one that consistently keeps my mouth feeling fresh without that overpowering artificial mint or gritty texture.
This formula is gentle but effective, no burning, no foamy overload, and no funky aftertaste. It’s also a huge win that it’s sulfate-free and doesn’t irritate my gums like some drugstore pastes do. The mint is subtle but refreshing, and my mouth actually feels hydrated afterward (which is wild to say about a toothpaste, but here we are).
If you deal with dry mouth from medication, menopause, or just bad luck, this one’s worth every penny.
✨ Pro tip: Keep a travel size in your bag if you’re heading out for the day. Nothing ruins a coffee date like feeling like your tongue is made of sandpaper.
10/10 recommend.

Dry Mouth
Size: 4.3 Ounce (Pack of 1)
I have been diagnosed with Dry Mouth, what a problem this is! My dentist recommended toothpaste for dry mouth; I selected Biotene Fluoride toothpaste for daily use. I definitely use it at night before going to bed to help keep my mouth less dry. I also use Biotene mouth wash and other products that I'll rate another time. I love this toothpaste; I believe it's helpful for my diagnosis.

Biotène Fluoride Toothpaste for Dry Mouth Symptoms
Size: 4.3 Ounce (Pack of 1)
I have been using this toothpaste on and off for a few years ever since I got a dry mouth. It is very good and leaves your mouth feeling fresh. Unfortunately it doesn't get rid of your dry mouth.

Chemical free is important
Size: 4.3 Ounce (Pack of 1)
I don’t like doing fluoride, but I do know that some fluoride is important so this is the cleanest fluoride toothpaste I could find and I use it in conjunction with a non-fluoride toothpaste I have I love the flavor. I love the fact that it doesn’t have a lot of the bad chemicals in it.
