The Titleist 909 D3 driver is a 440cc volume driver designed to lower spin rates for player who generate too much driver spin & help create more distance. The classic pear shape profile lowers the centre of gravity lowering spin, increasing the MOI & helping you hit longer & straighter drives. The smaller head size with a deeper face enhances workability & superior shot making. 909 D3 features a tuned sole which helps stop vibrations & gives a much nicer sound from impact. The 909 D3 driver is fitted with the Aldila Voo Doo shaft which is designed to give a low-mid ball flight.
