Identifying the right model
- AEROJET lettering runs down from the toe end of a black and white sole with blue weight ports.
- Match the full model name and any suffix (LS, MAX, X, D, ONE Length, SELECT) on the head as well as the printed loft.
What to check before using the reference
- The figures come from an Internet Archive capture of Cobra’s US product page dated 2023-01-30.
- Loft and lie are the standard (STD) hosel setting. Cobra lists 8 hosel settings per head, including draw settings, so a used club may be set anywhere in the adjustable range shown.
- The source marks some left-handed builds with an asterisk; the page capture does not explain it, so availability of those builds is not established here.
Checking a club you own? These are the maker's published figures for an original build, not measurements of your club, and a source date is not the year it was made. Bending, reshafting or a hosel adjustment changes loft, lie and length, so identify the head by its own markings and have a fitter measure it when its history is unclear.
