Harmon Tour Design (HTD®) graphite shafts have won particular acclaim for their distance and accuracy among some of the world’s best players.
The secret behind the HTD’s design is a combination of Tour-proven Proforce tip technology and a new ‘Counter Balance’ design.
The HTD features an ‘active’ tip section that performs significantly different from the tip section found in most shafts. The HTD’s tip section is torsionally stable to control the clubhead, but more flexible to provide some feel and kick at impact. Beginning with the basic Tour-winning Proforce tip design, UST engineers strengthened the tip even more to control the clubhead and create a penetrating ball flight.
But the tip section is only half of the puzzle. Additional weight is distributed in the HTD by using extra carbon fiber material in the butt section to move the balance point towards the shaft’s butt end, thus providing more stability and control in a player’s hands. The end result is an easier swing, increased ball speed and more distance!
In 2002, UST teamed up with Butch Harmon and his brothers - Craig, Bill and Dick - to successfully engineer HTD graphite shafts. Now played by more than 100 Tour pros, HTD shafts also bring the Harmon brothers’ experience in ball flight performance to golfers of all skill levels.

When the first, eye-catching Proforce Gold shaft burst on the scene with a dramatic victory at the 1999 Masters, its revolutionary ‘Proforce Tip Technology’ shook up the golf equipment industry. With countless successes on the professional and top amateur circuits, as well as drawing rave reviews from golfers of all skill levels, the Proforce family of graphite shafts has emerged as one of the most successful graphite shaft series in golf history.
The phenomenal Proforce is specially designed to produce optimum results when playing with the larger driver heads that are so popular today. The Proforce’s Tour-winning ‘Tip Technology’ is engineered with increased torsional stiffness, or lower torque values, in the shaft’s tip section for a more solid feel and increased playability. Proforce Tip Technology also minimizes ‘shaft droop’ during the swing which causes the club’s toe to point down at impact and leads to inconsistent ball striking.
Since that original design won in Augusta, engineers at United Sports Technologies have garnered invaluable feedback from hundreds of PGA Tour pros who have played Proforce shafts in golf’s toughest venues. The result is the perfect blend of flexural stiffness and torsional stability! The Proforce’s tip flexibility provides enhanced ball speed and a penetrating ball flight, while its low torque tip section stabilizes the clubhead during impact and hel
