The Asetek QR Adapter Tube 146mm extends compatible quick releases to clear your wheel and dash. Learn what it fits, when you need it, and when you don't.
Quick answer
Buy the Asetek QR Adapter Tube 146mm only if you need to move an Asetek SimSports quick release 146 mm farther from the wheelbase to clear a wheel, dash, or button box. It is an all-aluminum extension tube, not a universal spacer, and it is compatible with the Invicta Quick Release Adapter and 3rd Party Wheelbase QR Adapter.
What the 146mm length actually buys you
The 146 mm figure is the added distance between your wheelbase-side quick release and the wheel-side quick release. That extra length can solve interference when a large rim, a deep dish, or a dashboard panel sits too close to the base. It does not change the quick release mechanism itself, so the release action and wheel mounting remain the same. If your current setup already clears everything, the tube adds length without a functional benefit.
Fitment is narrower than 'Asetek quick release'
Asetek lists compatibility with the Invicta Quick Release Adapter and a 3rd Party Wheelbase QR Adapter. That means the tube is designed to extend those specific interfaces, not every Asetek quick release or every wheelbase on the market. Before ordering, confirm which quick release adapter you have on the wheelbase side. If your adapter is not one of those two, the tube may not attach correctly, and the catalog does not provide a universal fitment chart to cover other combinations.
When a steering wheel extension is the wrong fix
An extension tube pushes the wheel farther away, which changes your driving position and can increase leverage on the wheelbase shaft. If your only problem is a wheel that sits too close to your body, adjust your cockpit seat or wheelbase mount first. Use the tube when the interference is between the wheel and the wheelbase or dash, not when you simply want a different reach. Also check that your wheelbase can handle the added offset without flex; the catalog does not list a maximum load or length rating, so treat that as an unknown and test carefully.
Common questions about the Asetek QR Adapter Tube 146mm
- Will this tube fit my Asetek wheelbase?
- Only if your wheelbase side uses the Invicta Quick Release Adapter or a 3rd Party Wheelbase QR Adapter. Check the adapter model before buying; the tube is not listed as compatible with other Asetek quick release interfaces. If you cannot identify your adapter, do not order yet.
- Does it work as a universal steering wheel extension?
- No. It is a specific adapter tube for Asetek SimSports quick release products, not a generic extension for any wheel or wheelbase. The catalog does not provide dimensions for other brands, so cross-brand fitment is unsupported.
- How much extra clearance does 146mm give?
- It adds 146 mm of length between the quick release interfaces. Measure the gap you need to clear your wheel or dash, then compare it to that figure. If you need less, the tube may move the wheel too far; if you need more, a single tube will not be enough. Measure before you buy, not after.
- Will the extension affect quick release operation?
- The tube extends the mounting point but does not change the quick release mechanism itself. You still operate the same release. The catalog does not list any additional hardware or tools required, so use the fasteners supplied with your existing quick release adapter.
- When should I skip this part?
- Skip it if your wheel already clears the wheelbase and dash, if you have not confirmed compatible adapters, or if your issue is reach rather than interference. In those cases, adjust your cockpit position or choose a different accessory. Clearance problem first, then buy.
Product facts
- Asetek QR Adapter Tube L. 146mm: All-aluminum tube, 146 mm long, designed to extend Asetek SimSports Quick Release products. Aluminum keeps the extension rigid, and the fixed 146 mm length gives you a predictable clearance gain rather than an adjustable spacer.
