How to identify this generation

  • Confirm M4 branding on the head and compare the cavity with the 2018 sheet.
  • The manufacturer describes this generation's RIBCOR design; consult the linked source for head photographs.
  • Use the archive year as well as the model name. TaylorMade also lists an M4 sheet in a later archive year.

What to notice in the specifications

  • Loft and lie figures match the 2017 M2 across the listed rows. Matching angles do not establish identical ball flight or feel.
  • The 2018 M4 lob wedge is listed at 35 inches; the 2017 M2 lob wedge is listed at 35.25 inches.
  • The source makes a club-by-club left-hand distinction. Do not assume an entire range is available in both hands.
  • TaylorMade’s 2021 archive column links an M4 sheet with the same lofts and lies from 4-iron to SW but longer men’s lengths (4-iron: 39.125 in, 5-iron: 38.5 in, 6-iron: 37.88 in, 7-iron: 37.25 in …) and no LW.
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.
