QUICK TURNING. HIGH ENERGY.
Crafted for quick turning response and smooth edge-to-edge transitions, Orangatang Knuckles are the ultimate high-energy bushing upgrade for carving, pumping, dancing, and freestyle longboarding. Poured in our extremely high-rebound Randy Thane formula for responsive, energetic turning. Juicier bounce, tighter package.
What's in the box? Pack includes two insert barrel bushings, two gumdrop bushings, two large cup washers, and two small cup washers. Washer colour may vary.
RESPONSIVE DESIGN
Two unique shapes for highly responsive and customizable turning. The inner diameter features precise tolerances for a snugger fit around the kingpin. The insert barrel features a small “step” to fill the gap between the kingpin and the hole of the hanger, reducing play in the assembly for a more precise response. The gumdrop is a smooth and subtle blend between a barrel and the more traditional cone shape, providing enhanced agility. The rounded edge allows for ultra-smooth turn initiation and improved interface with the washers.

COMPATIBILITY
Knuckles are compatible with most reverse-kingpin longboard trucks (including Paris V2 and V3, Bear, Randal, Carver, Gullwing, Tracker, Caliber, Atlas, Bolzen, Aera, Rogue, PNL, Ronin, etc).
They DO NOT work on any traditional kingpin (street) trucks, such as Independent trucks or Paris Street Trucks.
If your truck is not on this list it may not be compatible, so please check the measurements and compare with your current bushings.
INSTALLATION
In the standard configuration, the insert barrel is placed on the bottom or board side (insert oriented toward the truck hanger) and the gumdrop on the top or road side (smaller/rounded side toward the washer).
Also try double insert barrels (the height of the insert is half the thickness of a Paris bushing seat) or double gumdrops. Replace the included cup washers with flat washers for a less restrictive, more linear turning rate.

We want you to be happy with what you buy from Urban Wheelz. If something isn't right, here's how returns work.
Change of mind returns
Skateboards, skates, protective gear, clothing and accessories: 30 days. You have 30 days from the day you receive your order to request a return. Items must be unused and unworn, with all tags attached, in the original packaging and in a condition we can resell as new.
Electric scooters: 7 days. You have 7 days from pickup or delivery to request a return. The item must be unridden, free of marks or wear, and returned with the original box, charger, manuals and all accessories.
Return postage for change of mind returns is paid by you. Please use a tracked service, as we can't refund items lost on the way back to us.
Items we can't accept as change of mind returns
- Anything that has been used, ridden, worn or damaged after delivery
- Electrical parts for electric scooters and e-bikes, including batteries, controllers, chargers, displays, throttles and other plug and play parts. Once connected, we can't confirm they haven't been damaged, so they can't be resold
- Skateboard decks with grip tape applied at your request, or boards that have been set up
- Blind bag or mystery products once the bag has been opened
- Service parts, tubes and tyres once fitted
- Special order items, including electric bikes, parts and products ordered in at your request
- Workshop labour and servicing
- Gift vouchers
This list applies to change of mind returns only. It does not affect your rights if an item is faulty.
Faulty, damaged or not as described
Our products come with guarantees that cannot be excluded under the Australian Consumer Law. If an item is faulty, arrives damaged or isn't as described, we'll arrange a repair, replacement or refund as required by law. For a major failure, you can choose a refund or a replacement.
Please contact us before sending anything back so we can assess the issue. Photos or a short video of the fault help us sort it out faster. Electric scooters may need to be inspected in our Cairns workshop. Some claims are assessed with the manufacturer under their warranty, and we manage that process for you.
Return postage on fault claims. You pay the return postage upfront. Once we or the manufacturer confirm the item is faulty, we'll reimburse your reasonable return postage and send the repaired or replacement item back at our cost. If the problem is caused by crash damage, misuse, unauthorised modification or normal wear and tear, it isn't covered, and the item will be returned at your cost or held in store for collection. If an item is too large or heavy to return without significant cost, contact us and we'll arrange the next step with you.
If your order arrives damaged, let us know as soon as possible, ideally within 2 business days, and keep the packaging so we can lodge a claim with the carrier. Transit damage is covered at our cost.
Speed and range
Top speeds and range are manufacturer figures measured under test conditions. Rider weight, terrain, hills, riding mode, temperature and riding style all affect real world results. Lower real world speed or range on its own is not treated as a fault. If you think your scooter isn't performing as it should, contact us and we'll check it over.
How to start a return
- Email info@urbanwheelz.com.au with your order number, the item and the reason for the return. For faults, include photos or video.
- We'll reply within 2 business days with return instructions. Some products ship direct from our suppliers, so the return address may not be our Cairns store.
- Pack the item securely in its original packaging and send it with tracking. Items sent back without an approved return may not be accepted.
Bought in store or picked up from us? You're welcome to bring it back to 88-90 Mulgrave Road, Cairns with your receipt.
