Sleeve fitCallaway Quantum Mini Driver compatible shafts
The Quantum Mini Driver uses the Callaway OptiFit 4 adapter (Callaway connector system), OptiFit 4 (Quantum fairway wood, hybrid, and Quantum Mini Driver, 2026 to present) (0.335" tip).
Check your shaft
Type the model your shaft is currently in (or was pulled from) to see whether it fits the Quantum Mini Driver.
Drops straight in
Both use the , " tip. No reshaft, no builder. Re-check your loft position after the swap.
Fits, after an adapter swap
Not a drop-in. This shaft carries a ; the Quantum Mini Driver needs a . The shaft itself works: a club builder swaps the adapter for a small shop fee.
The shaft's " tip differs from this head's " tip, so the builder may need to re-tip it; it may not be a clean swap.
Does not fit
Fits, after an adapter install
That shaft has no adapter, it is glued into a fixed hosel. A club builder can cut it and install a adapter to make it fit this head.
Fit unknown
We have not verified that model's hosel hardware yet, so we cannot say whether its shaft carries an adapter or is glued in. Treat this combination as unknown rather than assuming a fit.
Not in our catalog
That model is not in our catalog yet. Report it so we can add it, rather than guess.
Sleeve interchange
Researched cases where a sleeve from another generation of this same brand does or does not fit this head.
| Sleeve family | Verdict | Notes | Source |
|---|---|---|---|
| Callaway OptiFit 2 | Does not fit | Reverse direction of the same pairing: the Quantum Mini's OptiFit 4 sleeve is not interchangeable with the OptiFit 2 driver sleeve used by every other Quantum trim and every other Callaway driver in this catalog. | Inferred from aftermarket sleeve part coverage, cross-checked across suppliers. |
| Callaway OptiFit 3 | Does not fit | Driver-generation OptiFit 2 (or OptiFit 4) sleeve is not interchangeable with the fairway-generation OptiFit 3 sleeve (callaway-optifit-3-fairway): GolfWorks sells these as separate, distinctly-numbered parts (CA0020/CA0029 for drivers, CA0024 for the 2019-2025 fairway generation), and CA0024's own page describes itself as 'a Smaller and lighter version of the original... Opti-Fit driver/fairway adaptor,' i.e. physically distinct from the current driver part despite the shared mechanism family. | Inferred from aftermarket sleeve part coverage, cross-checked across suppliers. |
Shafts that drop in from another head
A shaft pulled from any of these heads carries a sleeve the Quantum Mini Driver accepts, so it drops straight in, no reshaft.

Stock shaft
Any 0.335 inch tip shaft can be built for this hosel by a club builder; the sleeve, not the shaft model, is what decides whether a used pull drops in.
Shafts from other brands
Sleeve adapters are brand specific. A shaft pulled from a different brand's head carries that brand's sleeve, not this one, so it needs the sleeve swapped by a club builder before it fits this head.
Fit from Callaway Fairway & Hybrid OptiFit 4 Hosel Guide.
