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 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.
Callaway OptiFit 4	Does not fit	Same as above.	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 Paradym X Driver accepts, so it drops straight in, no reshaft.

Stock shaft

Aldila Ascent PL 44 g, R flex Callaway's own Paradym X driver product page lists Aldila Ascent PL Blue 40 (Regular) as one of several factory stock shaft options, alongside Project X HZRDUS GEN 4 Silver 50/60.

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.
