Replace the coil springs on your 2018-2023 Jeep Wrangler JL or 2020-2023 Jeep Gladiator JT with the Synergy 8863-40 4"-5" Front Lift Coil Springs from GAP. Synergy MFG has designed these springs from a clean sheet for the new Wrangler platform. All springs are multi-rate and have been designed to make a great platform even better. These springs are unique to the JL and not shared with the JK or other vehicles. Like OEM, Synergy coil springs are unique lengths to account for load differences on each corner of the vehicle. There are right and left specific springs front and rear to guarantee the vehicle will sit level. Springs are designed to be used with up to .75 inch of front spring spacer without requiring additional bump stop spacing. The multi-rate design has a softer initial rate which prevents the spring from coming loose in the coil tower, even with long travel shocks. The ride rate is slightly stiffer than the OEM springs to account for additional weight from bumpers, winches, skid plates and gear. Springs are proudly manufactured in the United States of the highest quality steel. Springs are designed to be able to set solid (fully collapse) without overstressing the material and are pre-set from the factory meaning the springs will never sag or set.
Features:
- Multi-Rate Coil Springs Allow For Longer Spring Lengths And Increased Travel
- Spring Rates Are Only 5-10 Percent Stiffer Than Stock For Superior Ride Quality
- Coil Spring Block Heights Are Designed Around Common Bump Stop Spacings To Optimize Wheel Travel
- Ground And Closed Lower Spring Ends To Prevent Bowing
- Includes Front Lower Coil Spring Isolators To Match The Ground And Closed Spring Ends
- Unique Spring Lengths For Each Corner Of The Vehicle So It Will Sit Level Side To Side
- Frequency-Balanced And Tuned Spring Rates To Maximize Suspension Performance On And Off-Road
- Abrasion-Resistant Black Powder Coat Finish For Maximum Durability And Corrosion Resistance
Note: 4-Door Lift Height: 4"
2-Door Lift Height: 5"
Coil springs require proper bump stop spacing with Synergy 8057-10 Bump Stop Spacers.
Lift heights are based off fully loaded Rubicon models. Other models will see more lift.
Coil springs retain the stock rake of the vehicle.
Up to .75 inch of front coil spring spacer can be added to level the vehicle using 8017-075 front coil spring spacers.
Min bump stop spacing listed is the minimum amount of bump stop spacing required to prevent the springs from going into coil bind. Do not use less bump stop spacing.

Anker 332 USB-C Hub (5-in-1): The Swiss Army Knife of Connectivity
Color: Black
Ever felt like your laptop was playing a cruel joke on you with its lack of ports? Enter the Anker 332 USB-C Hub (5-in-1)—the tech equivalent of a superhero swooping in to save the day (and your productivity).
Port Party
This hub is like the ultimate party host: it’s got a little something for everyone. Need to connect an external monitor? Boom, there’s a 4K HDMI port. Want to transfer files faster than a cheetah on a caffeine rush? It’s got two 5 Gbps USB-A ports and a 5 Gbps USB-C data port ready to go. Oh, and don’t worry about keeping your laptop charged while you’re multitasking like a boss—there’s a 100W PD-IN port to keep the power flowing.
4K HDMI: Because Why Settle for Less?
Let’s talk about that HDMI port, shall we? We’re talking 4K at 30Hz, which means your Netflix binge or work presentation will look crisp, clean, and oh-so-satisfying. It’s like upgrading from VHS to Blu-ray—you won’t believe you ever survived without it.
File Transfers in a Flash
Remember the days when transferring files felt like waiting for dial-up internet to connect? Yeah, those days are over. With up to 5 Gbps transfer speeds, you can move files so fast that you’ll barely have time to grab your coffee before it’s done. Just think of all the time you’ll save—and how much more you can procrastinate as a result!
Pass-Through Charging: Power Up, Don’t Power Down
One of the worst feelings in the tech world is watching your battery icon turn red while you’re in the middle of something important. But fear not—this hub’s got you covered with up to 85W pass-through charging. So, go ahead and keep doing whatever it is you’re doing, whether it’s crushing deadlines or browsing cat memes (no judgment here).
Compact and Reliable
The Anker 332 USB-C Hub is compact enough to slip into your laptop bag without a second thought. And with an 18-month worry-free warranty, it’s clear that Anker has your back—just in case you get a little too enthusiastic with all those ports.
Final Thought
In a world where laptops keep losing ports faster than you lose socks in the laundry, the Anker 332 USB-C Hub is the perfect solution. It’s reliable, versatile, and just what you need to bring your laptop back to life. So go ahead—plug in, power up, and let the good times (and files) roll!

Reliable Hub That Gets the Job Done
Color: Blue, Color: Blue
Solid Anker USB C hub that does what it’s supposed to do. Ports work well and it’s easy to use right out of the box. Only downside is the hard plastic casing, it feels fine, but I could see it cracking if something heavy drops on it.

Excellent device, see my use case in the review.
Color: Grey
I got the hub in two days ago. I plugged it in to a uni-directional HDMI cable (I have used these for years from Monoprice.com) from the hub to the TV and the PD port into the charging block. Charging started but the iPad Pro screen was NOT showing on the TV.
I switched in a regular HDMI cable from the hub to the TV and it worked. The Monoprice cables have some sort of logic in the cable ends allowing a very thin HDMI cable. I have used these on my TVs at home and when teaching at a senior facility for at least 8 years now.
So, something with the unidirectional HDMI cables seems to interfere with this hub but “regular” HDMI cables seem OK.
Before buying this hub, I had emailed Anker TS with a question. Anker turned around 3 emails with answers in just over an hour. This is one of the reasons why I have bought quite a lot of Anker products over the years.
My use for this is to plug in my iPad Pro to my AVR so that I can stream stuff to my TV while simultaneously charging the iPad at the same time. This works well.

Works great and handles everything.
Color: Black
Works great. I plug in a standalone video camera for meetings, a keyboard & trackball, and monitor with a couple of other slots open, like for a portable CD-ROM/DVD player. One plug into the laptop and everything is connected. Initially, I bought another hub, but that one didn't consistently work. This one does. In a month of heavy use, I've had no issues with it at all.

Helped transfer data from Samsung Galaxy S21 with broken screen.
Color: Black
Helped me transfer data from a Samsung Galaxy S21 with broken screen. Simple put USB C end into phone , grab HDMI cable and plug into hub , then plug HDMI end into a monitor. Then grab a wireless keyboard & mouse and plug dongle into hub. Your phone will output to monitor and you can transfer data via Smart Switch using keyboard & mouse. Will only work if phone is unlocked I found on S21.
