Metal Wheel Hex Hub Adapters for 1/10 ARRMA 3S Models
I picked up this set of 12mm Metal Hex Hub Adapters mainly because my stock plastic hexes were starting to strip out after a few months of bashing my ARRMA Big Rock 3S. These aluminum ones caught my eye due to the price-to-quality ratio and the fact that they’re listed as one of the top sellers in their category. With CNC-machined aluminum and included pins and screws, the value seemed too good to ignore.
Delivery took just under three weeks to the US, which honestly wasn’t bad at all. Everything arrived well-packed with no missing pieces. Installing them was easy—just pop off the wheels, pull the old hubs, slide these on with the pins, tighten the screws, and you’re good to go. Fitment was perfect, no wiggle or tolerance issues.
Pros: – Solid anodized finish – Precise fit on axle and wheel – Much stronger than plastic OEM parts – Affordable upgrade
Cons: – Not threaded inside for easier installation like some higher-end ones – Slightly heavier than plastic (but that’s expected)
Compared to similar parts on Horizon Hobby or Amazon, these cost literally 1/3 of the price. I’ve already done a few bashing sessions with hard landings, and the hexes haven’t budged or shown wear. Expectations exceeded for sure. For anyone running ARRMA 3S cars, this is a must-have upgrade.

22 Pcs Steering & Shock Ball Link Kit for ARRMA 1/10 3S Models
I ordered this pivot ball & tie rod set mainly to refresh the worn steering parts on my Typhon 3S. Over time, the stock plastic ends tend to loosen and wobble, especially after a few crashes. This 22-piece kit promised a full refresh for both suspension and steering linkage points—and the price was too good to pass up.
Shipping was smooth, with tracking updates throughout. It took about 2.5 weeks to arrive. The kit came well-organized in a plastic pouch, and the components looked solid at first glance. All parts installed without issues, and they’re a noticeable upgrade from stock in terms of stiffness and precision. The slop in the steering is gone, and I’m seeing tighter handling in general.
Pros: – Excellent fitment – Full set for both front and rear – Reinforced material (feels more durable than stock) – Quieted the suspension a bit
Cons: – No instructions (but it’s fairly intuitive if you’ve worked on RCs) – A few ball ends were tight and needed light sanding
Compared to US prices, this kit is under half the cost. Local hobby shops charge $15–20 for just 4–6 pivot balls. For a full set at this price? Total win. Definitely met my expectations—and then some.

Metal 23T/25T Servo Saver w/ Linkage for ARRMA RC Cars
My servo saver finally gave up during a rough crash on my Kraton 4S, so I ordered this aluminum servo saver with fixed linkage as a more durable replacement. What attracted me was the dual compatibility (23T and 25T) and the CNC-machined aluminum construction, which looked beefy in the photos.
The package arrived in 18 days, all parts intact. Install was straightforward—used the 25T adapter for my Spektrum servo, and everything bolted up cleanly. The fixed linkage bar feels much tighter than stock, which adds a snappy feel to the steering. No more vague center-point issues, and it absorbs hits better.
Pros: – Excellent build quality – Fits perfectly with stock servo – Better steering response – Eliminated play in the steering rack
Cons: – No instructions or labels on which adapter is 23T vs. 25T – Not spring-loaded like some high-end servo savers
For less than $10, this is a no-brainer compared to $25+ options stateside. It performs great on the track and while bashing. It absolutely met my expectations and honestly improved my driving feel.

26PCS Ball Bearing Kit for ARRMA 3S BLX Models
I got this blue-sealed bearing set to replace all the stock bearings on my Senton 3S, which were beginning to seize and rust after months of use. I’ve seen this kit recommended a lot in forums, and at under $10, it was worth trying.
It arrived quicker than expected—only 12 days! All bearings were sealed in a labeled bag, which made installation easy. They spun freely out of the package, and after installing them, my drivetrain felt noticeably smoother. The blue rubber seals also add a touch of visual appeal if that matters to you.
Pros: – Full replacement set (no missing sizes) – Smooth rolling – Blue seals help keep out dust and moisture – Way cheaper than FastEddy bearings
Cons: – Not ceramic or high-speed rated – Slightly more resistance out of the box (they break in fine)
These cost a fraction of what I’d pay for name-brand kits in the US. I was pleasantly surprised by the quality. The bearings met expectations and then some—my rig rolls better now and sounds healthier.

Adjustable Motor Mount for ARRMA 3S & 4S RC Cars
The metal adjustable motor mount caught my eye because I recently upgraded my motor and needed something to help fine-tune mesh. This looked like a solid upgrade from the stock stamped part. I also liked that it fits a wide range of models across the 3S and 4S lineup.
Shipping took just over two weeks, and the part came individually boxed and bubble-wrapped. The finish is nice—black anodized, no burrs, and machined clean. Installation was simple, and I appreciate the clear markings for different pinion sizes. It makes adjusting the motor mesh almost foolproof.
Pros: – Tight tolerances – Markings for gear settings – Stays solid under torque – Helps reduce motor temps
Cons: – A little heavier than stock – No installation guide
U.S.-based CNC mounts like this go for $25–30. This one was less than half that and works just as well. It’s rock-solid and made my setup smoother and more reliable. Definitely exceeded expectations.

YEAHRUN Aluminum Center Driveshaft Support for ARRMA 3S
I bought this center driveshaft bearing support after hearing a weird rattle during acceleration on my Vendetta 3S. Turns out the center shaft was flexing a bit under load. This aluminum brace was a popular mod in forums, so I gave it a shot.
Shipping was under three weeks, and the part arrived looking even better in person—clean machining, anodized finish, and pre-installed bearing. Install took less than 10 minutes. Immediately, the drivetrain felt tighter, and the rattling noise disappeared.
Pros: – Stops driveshaft vibration – Very sturdy – Easy install – Comes with bearing
Cons: – Doesn’t include extra screws – Adds minor weight
On Amazon or in the US, a similar part would cost around $18–20. This one was under $8 and works flawlessly. It definitely met expectations and added unexpected value in terms of smoother power delivery.
US $12.96
Overall Thoughts
Honestly, I’m surprised by how good these AliExpress parts turned out to be. I went in expecting average quality but got upgrades that truly perform. Every item fit properly, improved my RCs in some way, and cost a fraction of what I’d spend locally. Shipping times were reasonable and consistent across all six items.
Would I recommend these? Absolutely—especially if you enjoy wrenching and know your way around ARRMA cars. I plan to keep buying from the same sellers. These upgrades made my fleet tougher, tighter, and more fun to drive without breaking the bank.
