The U.S. Kids Golf RS63 Swing Speed Trainer is a purpose-built junior training aid designed to help young golfers develop a faster, more powerful swing while simultaneously building proper technique and Tour-like tempo. Matched to the UL63 (160 cm) size system, it gives players in the 160 cm height range a correctly proportioned tool that feels natural from the first practice session. Whether your junior is just beginning to push their swing speed or is looking to add meaningful yards to their drives, the RS63 is the focused, daily-use solution recommended by U.S. Kids Golf coaches worldwide.
The RS63 Swing Speed Trainer is engineered with a lighter head weight than a standard golf club, which enables a junior golfer to swing the trainer noticeably faster than they could a regular club. Over repeated sessions this overspeed stimulus trains the neuromuscular system to recruit more muscle fibre and fire faster, producing a measurable and lasting increase in club head speed when the player returns to their regular set. Consistent use progressively raises the ceiling of a young golfer's swing speed, directly translating to greater distance off the tee.
One of the most critical yet often overlooked fundamentals in junior golf is swing tempo — the smooth acceleration from address through impact to follow-through. The RS63 helps junior players develop a fluid, rhythmic swing that mirrors the tempo of Tour professionals. Because the trainer swings faster and more freely than a weighted club, it encourages the player to sequence their body rotation and arm swing correctly, building muscle memory for an efficient, repeatable motion. Good tempo is the foundation of consistent ball striking at any level.
The shaft length of the RS63 Swing Speed Trainer is identical to that of the UL63 Ultralight driver — 42 inches — ensuring that every practice swing translates directly to the feel and mechanics of the actual club a player uses on the course. There is no adjustment period or muscle-memory conflict when switching from the trainer to a real driver; the two feel proportionally identical. This length-matched design is a deliberate part of the U.S. Kids Golf fit-by-size philosophy, which pairs equipment and training tools precisely to player height for optimal development.
U.S. Kids Golf recommends as little as 5 minutes of daily training with the Swing Speed Trainer to achieve noticeable, sustained improvement in drive length and straightness. Short, focused sessions work with the body's natural adaptation cycle — frequent, brief overspeed training sessions are more effective than infrequent long ones. Parents and coaches find the short session requirement easy to integrate into warm-up routines or practice schedules, making the RS63 one of the most practical training aids in a junior golfer's bag.
Unlike many training aids that are manufactured in separate right- and left-handed versions, the RS63 Swing Speed Trainer works equally well for both handedness orientations. This makes it a versatile tool for coaches working with groups of mixed-handed players, and eliminates any purchasing confusion for families. There is no functional difference in the training effect regardless of which hand leads — the same speed and tempo benefits apply to every junior golfer who picks it up.
The RS63 is part of U.S. Kids Golf's comprehensive fit-by-height equipment ecosystem. By selecting the 63 size, you ensure the training aid is correctly proportioned for a player measuring approximately 160 cm (63 in) in height — the same height band as the UL63 Ultralight club series. Using correctly sized equipment from an early age promotes sound posture, proper spine angle, and natural swing plane development, all of which are harder to achieve — and harder to correct later — when a junior uses equipment that is too long or too short.
The chart below illustrates the swing speeds that junior golfers of different heights and skill levels should aim to achieve. Use it to track your child's progress and set meaningful development goals as they improve with the RS63 Swing Speed Trainer.
