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.

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.

Better than thin plastic boards
I used to use one of those thin/bendable plastic cutting boards, thinking it's easier to transfer food into pots/pans from the board, but they tend to get bent in time and they're simply too thin and I hated the feeling of my knife pretty much hitting the kitchen counter.
So, I decided to buy this set. I wanted to try a wooden board, but didn't want to spend too much in case I didn't like it, and this set had the perfect price tag and I liked the fact it came with 4 different sizes, so that I can see what size would actually be more useful.
I've been using it for 2 months now they're doing great (except one of them started splitting a bit and started showing some strange black dots on the side... possibly mold??? though I can't think of any reason why mold would grow on just one of them. Maybe it's related to the fact that it's the only one that's cracking. And this is the only reason why I gave 4 stars instead of 5.)
Anyway, apart from that one, the rest are doing well and having 3 boards is plenty.
I like the juice groove to avoid spilling liquid on the board, as it happened so many time using the bendable plastic boards.
I'm handwashing them with dish soap. They seem to dry pretty fast, and so far no stains etc. on the surface. They're not super duper thick so even the largest one is not too difficult to handle.
I sometimes use them to serve some food like appetizers, snacks, pizzas and sandwiches, etc. too!

Updated review: spitting and splintering
UPDATE:
Originally, one of the boards arrived with a split in it, but I was still happy with them. After a few weeks of light use, hand washing and drying of the boards, I figured it was time to update this review and knock these down to 1 star.
The boards do not hold up very well. Cut marks are deep, and they are starting to splinter. Another of the boards has also developed a split.
Save your money and go with cutting boards from someone else.
ORIGINAL REVIEW:
I bought these cutting boards to cut down on microplastic exposure. This would be a 5 star review except that one of the boards arrived cracked (noticed while hand washing all of them before use). Despite the one cracked board, I did not return them, as I immediately started using the boards, was too busy to deal with it at the time, and the overall value was still there.
These boards are great, the value is excellent since you get several of different sizes. I like that all sizes have the moat for juices, because sometimes you are cutting one or two chicken breasts or one steak and don’t want to have to grab a big board.
I honestly am writing this review because I wouldn’t be surprised if the company sends me a replacement. If they do, I will update the review to reflect their customer service.
