Frequently Asked Questions
-
Is the adapter tip already installed?
Yes. Every shaft here is built to order with a genuine Cobra-compatible adapter tip epoxied and trimmed before shipping. When it arrives, insert it into your Cobra driver hosel and tighten with your standard Cobra wrench — nothing else needed.
-
Which Callaway driver models are compatible?
We carry adapters for Cobra driver and fairway models including the Aerojet, Aerojet Max, Aerojet LS, LTDx, LTDx Max, LTDx LS, Radspeed, Radspeed XB, F9 Speedback, F8, F8+, King LTD, King F7, and more. If you do not see your exact model, text us at (408) 475-7570 to confirm compatibility.
-
What shaft should I choose for my Cobra driver?
Cobra drivers tend to pair well with mid-weight shafts in the 55–65g range. If you are playing a Radspeed or LTDx and want more control, the Project X HZRDUS Black or Fujikura Ventus Black deliver a firmer, lower-spinning feel. If you want more distance and higher launch, the UST Mamiya Lin-Q or Mitsubishi Tensei AV Blue are popular choices. Our team is available by text at (408) 475-7570 to help you match the right shaft to your swing.
-
What length should I order?
Standard driver shaft length is 45.5 inches tip-to-butt. Most golfers order standard length. If you are building for a specific playing length, measure your current shaft from the top of the adapter to the end of the grip and order that length.
-
Can I return an assembled shaft?
Assembled shafts are custom built to order and are not eligible for return once built. Please double-check your adapter model, flex, and length before ordering. Contact us by text or email before placing your order if you have any questions.
-
How long does assembly and shipping take?
Most assembled shafts are built and shipped within 1–3 business days. Free shipping on orders over $99. Total delivery time is typically 3–7 business days.
