OXZAOX Lock vs T8: the migration guide
What each connection is
- T8
- Industry interface shared by SAB, Phantasm-style and several other foils. Wing bolts to the fuselage; bolts carry part of the bending load.
- OX Lock
- OXZA quick-connect. Load sits on a machined shoulder; bolts only clamp. Lower torque, higher measured stiffness, 6 mm titanium hardware.
- EZ
- Connection on the C (EZ), L and R wings. Own fuselage interface; not T8, not OX.
- MTC
- Twin-Connect mast — board-side only. Pedestal or tuttle mount. Independent of the wing connection.
The connection that matters for migration is the wing-to-fuselage one. The mast-to-board interface (plate, tuttle, pedestal) is separate and, for most T8 riders, does not need to change.
Side by side
| T8 | OX Lock | |
|---|---|---|
| Who uses it | SAB, Phantasm-style, many others | OXZA REVSTAR |
| Load path | Bolt threads + faces | Machined shoulder; bolts clamp only |
| Play after a season | Common | Designed out — see the rev 14 log |
| Beach assembly | Wrench, moderate torque | 6 mm key, low torque |
| Hardware | Varies by brand | Titanium, one spec across the system |
| REVSTAR wings available | A family (all), C 640 / 690 / 800s | Coming to every family as OX fuselages ship |
| REVSTAR fuselages available | FU600 / FU700 / FU860 in AL, CF, TI | FU600 / FU700 / FU860 in AL, CF, TI; FU1000 TI only |
The migration path
Step 1 — keep your mast
Your existing mast connects to the fuselage, not to the wing. Every REVSTAR fuselage in T8 is built to take the T8 masts riders already own. Nothing to buy here.
Step 2 — change the fuselage
The fuselage is the hub. Pick the length by how you ride — FU700 is the core all-around size — and the material by budget: aluminium now, titanium later. Choose the T8 version to stay compatible with your current wings.
Step 3 — add a REVSTAR wing
Any A-family wing drops onto the T8 fuselage. Most migrating riders start with the REVSTAR-A 725s or A 800 — the aspect-ratio guide explains which.
Step 4 — go OX when you are ready
Swap the T8 fuselage for the OX version in the same length and material, and move your front wing to its OX counterpart. From there every future part is OX Lock, and the system behaves as one piece.
What does not work
- A T8 wing on an OX fuselage, or the reverse. There is no adapter, and we will not sell one: an adapter adds a joint, and a joint is what OX Lock exists to remove.
- EZ wings (C 590s / 650s / 800s EZ, the L and R families) on a T8 or OX fuselage. EZ has its own interface.
- FU1000 on anything but titanium and OX. It is a windsurf race part and is built for one load case.
When in doubt, the compatibility chart is the source of truth — it is the same data the builder uses to refuse bad combinations.
Hardware note
REVSTAR ships with 6 mm titanium bolts. If you are reusing T8 bolts from another brand, check length against the hardware guide — too long bottoms out before it clamps, too short strips the thread.
Questions
Can I use my T8 mast with OXZA REVSTAR wings?
Yes. Every REVSTAR front wing in the A family and the T8 versions of the C family ship with a T8 interface, and every FU600 / FU700 / FU860 fuselage is available in a T8 version. Keep your mast, change the wing and fuselage.
What is the difference between OX Lock and T8?
T8 is a widely used wing-to-fuselage interface. OX Lock is OXZA's own quick-connect that moves the bending load onto a machined shoulder instead of the bolt threads — stiffer, lower torque, no play over time. They are not cross-compatible.
Which part should I migrate first from T8 to OX?
The fuselage. A REVSTAR fuselage in T8 lets you keep your existing mast and T8 wings today; swapping it later to the OX version converts the whole system at once.
Are OX and T8 wings interchangeable?
No. An OX wing only mounts to an OX fuselage, and a T8 wing only to a T8 fuselage. OXZA keeps both fuselage lines in every size so you choose the path, not the brand.
