The ultra-lightweight Seamless Thermoform Crown on GT2 and GT3 fairways is made of the same new Proprietary Matrix Polymer found in GT drivers. The density of the Proprietary Matrix Polymer is about five times lighter than steel, giving Titleist engineers significant weight savings in comparison to prior generation fairway crowns, while maintaining Titleist’s classic sound and feel. The crown is also completely seamless, offering a player-preferred look at address without compromising any of the performance gains from GT’s multi-material construction. To accommodate the varying centre of gravity targets between the two models, GT2’s crown uses more Proprietary Matrix Polymer than does the GT3.

The discretionary mass gained from GT fairway woods Seamless Thermoform Crown allowed Titleist engineers to reposition the centre of gravity in each model to achieve optimal performance. GT3's CG is moved deeper to allow for a higher launch while keeping spin in a low but playable window.

Each of the three GT3 loft configurations features a refined SureFit Adjustable CG Track System, which allows fitters to move a sliding weight track into one of five positions: H2 (Heel), H1, N (Neutral), T1 (Toe), T2.
