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.

Longtime Berkshire Buyers 🩶
Color: Stormy Weather, Size: King (90 in x 108 in)
We have been Berkshire buyers for years and they never disappoint with their quality. They always make the best bedding on the market at a reasonable price point. In the economy we currently live in, it's getting harder to find quality products that don't break the bank & Berkshire has been consistent for years!
This blanket is no different & has held up to their name and brand. This blanket is large, which I love. There's nothing more annoying than trying to cover your whole body with a 50x60 sized blanket lol. This blanket is most definitely aesthetically pleasing but also keeps us warm. It feels like this blanket traps our own body heat and keeps it contained instead of producing heat, making us hot. We always stay a nice, consistent temp without getting overheated and sweaty....nobody wants that lol. It's made from high-quality fabric that isn't only soft and comfy but it's woven tightly and has held up wonderfully for how much we use it! This blankey also washes really well ((i.e. zero shrinkage, dries in an adequate time, no color fading and/or bleeding)). I also appreciate that even though this blanket keeps us warm, it isn't heavy & pretty lightweight compared to some of our other non Berkshire blankets. The color is also a rich blueish, cool colored gray that accentuates all of our decor and other bedding.
Overall, Berkshire has always been a household name in ours. We love the quality, the consistency of knowing what we're getting when we purchase from their brand, and the prices are always crazy reasonable without sacrificing what you receive. Hands down another great item from their brand & we will always recommend ✔️

Soft, plush, lovely
Color: Blue Moment, Size: King (90 in x 108 in)
We got this blanket in king size to use in lieu of a comforter in the warmer months. It's incredibly soft and luxurious. It's thick enough to feel plush and heavy, but thin enough to be perfect for a cool summer night.
It feels like really excellent quality, too. This is not cheap thin fleece. I've only washed it once so far, but it seems like it'll hold up to many washes. It's big, though, at least in king size. It takes up pretty much our entire washing machine, so it needs to be washed by itself or with little else. To dry, I tossed it in the dryer for 40 minutes or so on medium heat and then hung it over a banister to finish drying, and this seemed to work well.
It's also a very pretty blue, like a dusky light blue, just lovely. Overall, I'm very happy with this blanket.

A good lightweight blanket
Color: Blue Moment, Size: Twin (60 in x 90 in), Color: Blue Moment, Size: Twin (60 in x 90 in)
With perpetually dry hands I have issues with certain fabric textures. This Velvetloft blanket is on the border of triggering, but nothing like how the Classic Extra-Fluffy Plush throw is. The ribbing is interesting visually, but also made the blanket feel a lot lighter too. Definitely one I'll keep on the couch for a chilly day and not for my bed.
When I washed it I was expecting a lot of shedding like the Classic one, but there wasn't as much. I washed it on cold and dried it on the delicate setting since I don't have a good place to air dry. It doesn't appear any worse off than before I washed it.
Overall I like this one way more than the Classic, but the Primalush wearable blanket is still my favorite.

Wait until you unroll this beautifully soft blanket! It’s the one you want.
Color: Goose Egg, Size: Twin (60 in x 90 in), Color: Goose Egg, Size: Twin (60 in x 90 in)
I can’t pass up a good blanket, and boy is this one impressive! It’s another high-quality product from Berkshire Home Company.
What I love about my goose-egg colored, velvety soft, blanket is the ribbed design. The lines separate the elevated design, and I could literally rub my hand over it throughout an entire movie!
It’s SO plush and soft. It’s made from their signature VelvetLoft fabric. Plus the design makes it look like a planned piece of your decor. I like the color I chose but there are others to choose from as well.
It’s nice and thick but not too warm. I got the 60”x90” twin size which is great for me! Next time I will get a queen size to go over my bed.
The price point is so low for the quality you get! You should stop your search now because this is the best one!
