Stock lofts compared

Each cell lists the heads sold at that stock loft, factory standard. Adjustable hosels extend every head beyond its stamped loft — each model page has the full settings chart.

What the differences mean

Both families are sold in 4 heads — TSR1, TSR2, TSR3, and TSR4 for the TSR, GT1, GT2, GT3, and GT4 for the GT.

Stock loft coverage is identical: both run 8° to 12° across the same 5 stock lofts.

Adjustability is a wash: both use the same hosel system (SureFit hosel, −0.75° to +1.5° of loft, 16 settings), so a given head reaches the same effective loft window in either generation.

The GT arrived 2 years after the TSR as its replacement. Driver generations usually carry over the loft ladder and move the technology — face design, adjustability, head options — so the older family is the value buy on the used market while the newer one holds retail price.

Which should you choose?

The GT is the newer generation, so it carries the current face technology and full retail availability; the TSR is the value buy used or on closeout. If the head and loft you want is only in one lineup, that decides it — otherwise the newer family is the default at equal prices, and the older one the smarter buy at a real discount.

Both families are charted in full on their own pages: Titleist TSR driver specs and Titleist GT driver specs.
