Hosel adjustment chart
SureFit hosel · loft −0.75° to +1.5° · 16 settings.
Lie adjusts independently of loft, from 0.75° flat to 1.5° upright. Loft changes open or close the face slightly at address; SureFit's ring and cog adjust loft and lie independently, unlike single-axis sleeves.
| Setting | Loft | Lie |
|---|---|---|
| A1 | std | std |
| A2 | std | 1.5° upright |
| A3 | +1.5° | 1.5° upright |
| A4 | +1.5° | std |
| B1 | std | 0.75° flat |
| B2 | std | 0.75° upright |
| B3 | +1.5° | 0.75° upright |
| B4 | +1.5° | 0.75° flat |
| C1 | −0.75° | 0.75° flat |

The chart below is the right-handed chart; A1 is the standard setting. For left-handed drivers the chart mirrors and D4 is standard. Every TSi head, the TSi1 included, carries the SureFit hosel, and the sleeve interchanges forward through the TSR, GT and GTS.

About the Titleist TSi
The TSi is Titleist's 2020-2022 driver generation, remembered for its ATI 425 aerospace-titanium face — an alloy from a single Pittsburgh foundry, roughly 30% more ductile than standard 6-4 titanium, used across all four heads. The TSi2 (high launch, forgiveness-first) and TSi3 (traditional pear shape, and Titleist's first driver with the five-position SureFit CG track) arrived in November 2020; the ultralight TSi1 and the compact low-spin TSi4 followed in early 2021. The TSi3 in particular became one of the most-played drivers on tour of its era. The TSR generation replaced the family in late 2022.
Head variants
The heads this family is sold in, with each one’s stock loft options.

- The ultra-lightweight head — about 40 g lighter than a standard build — with high launch and slight draw bias for swing speeds up to roughly 90 mph. 9° and 12° are right-hand only; left-hand stock is 10°.
- TSi28°, 9°, 10°, 11°
- The high-launch, forgiveness-first distance head. The 8° head had limited availability and was dropped from later catalogues.
- TSi38°, 9°, 10°
- The mid-launch, pear-shaped fitter's head — Titleist's first driver with the five-position SureFit CG track (two heel, neutral, two toe positions).
- TSi48°, 9°, 10°
- The smallest, lowest-spinning head of the family for high-spin fast swingers, with a −4 g to +4 g interchangeable headweight kit. 8° and 10° are right-hand only; left-hand stock is 9°.

Frequently asked questions
What lofts does the Titleist TSi come in?
The TSi2 came in 8, 9, 10 and 11 degrees (the 8 was later dropped); the TSi3 and TSi4 in 8, 9 and 10; and the lightweight TSi1 in 9, 10 and 12.
What is the Titleist TSi SureFit chart?
The 16-setting SureFit hosel combines four loft positions (−0.75, standard, +0.75 and +1.5 degrees) with four lie positions (0.75 flat, standard, 0.75 upright and 1.5 upright). A1 is standard for right-handers; the left-hand chart mirrors with D4 as standard.
What was special about the TSi face?
All four TSi heads used ATI 425 aerospace titanium, an alloy about 30% more ductile than the usual 6-4 titanium, which let Titleist push a thinner, faster face while staying within the rules. Titleist stopped naming the face alloy in later generations.
Is the Titleist TSi still in production?
No — it ran from late 2020 to 2022, when the TSR replaced it. It remains common on the used market, and its SureFit sleeve means shafts from any TS through GTS generation fit.
Finding one used
The Titleist TSi ran from 2020 to 2022 and is no longer in production, so the used market is the only source. Search the used listings on eBay. Before buying used, check the stamped loft against the chart above and ask which hosel setting it is in — an adjustable driver may be set a degree or more away from the number on the sole, and sleeve adapters are brand- and generation-specific.

- Note: Titleist's own US spec table lists the TSi4 at 425 cc while essentially all launch coverage says 430 cc; 430 is charted here. The TSi2's 8° head was available at launch but absent from later catalogues.
