The U.S. Kids Golf UL7-48 (122 cm) W20 Junior Driver is a purpose-built driver from the seventh generation Ultralite series, designed for young golfers standing 122–130 cm tall (approximately 7 years old). Engineered from the ground up for beginning to intermediate players, it helps junior golfers hit the ball higher, farther, and straighter from their very first drives. Every design decision — from the re-engineered aerodynamic head shape to the ultra-light K-Flex graphite shaft — is focused on one goal: giving young players the best possible start in the game.
The re-engineered head shape, refined through detailed aerodynamic research, makes the UL7-48 the fastest driver U.S. Kids Golf has ever produced in this size category. Optimized using Trackman technology with thousands of real-world data points, the driver is proven to maximize distance and forgiveness for junior swing speeds. The higher loft and lighter head work together to produce a high launch angle and reduced spin, delivering longer, more consistent drives even for players still developing their technique. A thinner face and crown further increase ball speed at impact, pushing distance to its maximum.
Every dimension of the UL7-48 driver — from face angle and loft to head volume and shaft stiffness — was refined using Trackman launch monitor technology and thousands of on-course data points. This data-driven engineering process ensures that the club delivers the ideal combination of launch angle, spin rate, and ball speed specifically for junior swing speeds. The result is a driver that is genuinely optimized for how young golfers actually swing, rather than being a scaled-down version of an adult club. Players and parents can be confident they are using equipment that is scientifically proven to maximize distance and forgiveness for this age and height range.
The UL7-48 features a completely re-engineered head shape developed through careful aerodynamic research, making it the fastest driver U.S. Kids Golf has produced in the Ultralite series. By reducing drag through the swing arc, the new profile allows junior golfers to reach higher clubhead speeds with the same effort, translating directly into greater distance off the tee. The redesigned crown and sole profile also contribute to a lower, deeper center of gravity, improving launch conditions and reducing unwanted spin. Together, these aerodynamic advances help young players experience the feeling of a truly powerful drive, building confidence from their very first rounds.
The w20 designation means the clubhead is 20% lighter than a standard adult driver head — a critical advantage for young players who are still building strength and swing speed. This reduced mass allows the K-Flex shaft to load and unload efficiently through impact, maximizing energy transfer to the ball. At the same time, the head geometry is engineered for a high moment of inertia (MOI), meaning the face resists twisting on off-center hits. Even when contact is not perfectly centered, the ball still launches on a playable trajectory, encouraging young golfers and keeping them engaged with the game as they develop their skills.
The 19° loft is carefully chosen for the swing speeds typical of players in the 122–130 cm height range. At slower swing speeds, a higher loft is essential to achieve sufficient launch angle and carry distance — a lower-lofted adult driver would simply produce low, short shots. The thinner face flexes more efficiently at impact, generating higher ball speeds across the face even on moderate strikes. The thinner crown reduces weight at the top of the head, allowing engineers to position mass lower in the head for an even higher launch trajectory. The combined effect is noticeably longer, higher-flying drives that reward developing junior golfers with instant, visible results.
U.S. Kids Golf's sizing philosophy is rooted in a simple but powerful insight: the correct club length, lie angle, shaft flex, and swing weight must all work together in harmony for a junior player to develop properly. The UL7-48 is designed specifically for players measuring 48–51 inches (122–130 cm) in height with shoes on. Using the wrong size — whether too long, too short, or too heavy — forces children to compensate in their swing, slowing development and building bad habits. By choosing the correctly sized UL7-48, parents ensure their child is swinging a club that is truly matched to their body, giving them the best possible foundation for long-term improvement.
The K-Flex graphite shaft is purpose-engineered for junior swing speeds, providing the ideal combination of lightness and flexibility to help young players generate maximum clubhead speed without overexerting themselves. Graphite construction significantly reduces overall club weight compared to steel, making the driver easy to swing repeatedly throughout a round without fatigue. The Size 48 velvet rubber grip is proportioned precisely for smaller hands, ensuring a comfortable, secure hold that promotes correct grip pressure and natural wrist hinge through the swing. Replacement grips in the same size are also available from U.S. Kids Golf as the club is used over time.
