(Assembled) UST Lin-Q M40X Red Driver Shaft with Adapter Tip + Grip
WHAT YOU NEED TO KNOW
The UST Mamiya Lin-Q M40X Red is the higher-flighted shaft in the Lin-Q M40X family. UST rates every build mid-high launch and describes it as a mid spin shaft, with Toray M40X carbon in the tip for lateral stability. We sell the 5, 6 and 7 series from A to X flex. It arrives assembled with your choice of adapter and grip, ready to attach to your driver or fairway wood head.

Who It's For
Good fit if you...
- Want a higher flight with mid spin
- Swing your driver about 75 to 105 mph
- Want a 57 to 75 g shaft
- Play senior (A), regular, stiff or x-stiff flex
Not the right fit if you...
- Already launch the ball too high: the TSPX Black is rated low launch
- Want a heavy, low-torque shaft over 75 g
How It Plays
UST rates every Lin-Q M40X Red build mid-high launch and describes the shaft as mid-high launch with mid spin.
Toray M40X is a high-strength, high-modulus carbon fiber. UST places it in the tip area, where it says it improves lateral stability and puts more energy into the ball at impact.
Weights run from 57 g (5 A) to 75 g (7 S), with torque from 5.8 down to 4.1.
