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:
Recommended addition of (8859-12) - Synergy Jeep JL / JLU / JT Sway Bar Link Disconnect Brackets on both Rubicon and non-Rubicon Models to maximize front wheel travel.Synergy MFG coil springs lift the vehicle the advertised height over stock based on a fully loaded JT Rubicon. Other JT models (Non-Rubicon/Mojave) 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-inches without affecting up travel or causing coil bind, 8017-075).
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.
Recommended aftermarket shock fitment if not running Synergy Tuned Shocks.
1. Rear shock mounts in the highest position (brackets closest to the body of the Jeep).
2. May not be compatible with stock wheel backspacing.

Our doggies favorite toy
Color: Yellow, Color: Yellow
This is our 3 dog’s favorite toy! We’ve had it for over a year, it’s lived outside for a while, was buried, found, taken all around the house. This toy shows up in the most random places and is still in tack (for the most part). They fight over this toy. They also have the pig from the same brand and it’s still alive! Other toys are usually shredded in a few days.

Not a strong toy for chewers.
Color: Yellow
Not quite as strong as its description. My dog chewed off its foot within the first 10 minutes . I expected it to be stronger because it’s made of Kevlar material but it’s not that durable. Save your money it is far from being durable / indestructible.

Leave a toy for the dog when going to work, and no housebreaking when coming back
Color: Purple-Blue, Size: 2pcs
The dog is quite clingy. Every time it sees me put on my shoes to go out, it gets nervous. Since having this bear around, when it goes out, its attention is all on the toys, and when it comes back home, its mood has become much more stable.

Keeps my dog busy and actually holds up
This jigsaw-style dog toy has been a game changer for keeping my dog entertained. The design is super versatile—you can spread peanut butter (or yogurt, wet food, etc.) into the grooves, and it keeps them busy licking for a long time.
What I like most is that it’s not just a lick mat—it’s also a durable chew toy. The material feels strong and holds up really well, even with a dog that usually destroys toys pretty quickly. Toys made from rubber or similar materials tend to last longer and are safer for chewing compared to softer options.
The grooves and compartments make it a little more challenging (in a good way), so it takes my dog longer to get through the treats. I’ve even tried freezing peanut butter inside, and that keeps them occupied even longer. Lick-style toys like this are great for slowing dogs down and keeping them calm and engaged.
It’s also been really helpful during times when I need a distraction—like when I’m busy, cleaning, or even during grooming.
Pros:
• Durable and holds up to chewing
• Can use peanut butter, yogurt, or other soft treats
• Keeps dogs busy for a long time
• Helps with boredom and anxiety
• Freezable for longer use
Cons:
• Can get messy depending on what you put in it
