Can a golf grip really increase your speed? We know it sounds crazy, but it almost always happens when golfers start playing grips that are the right size for their game.
To help golfers understand what kind of benefits they can get from switching to properly sized grips, we reached out to Keiser University to perform an independent test of all the different sizes of JumboMax swing grips.
The study and test was designed by the team at Keiser. It is currently in the process of being published for research purposes.

Fifteen subjects with various golf handicaps participated in the testing. Subjects warmed up prior to the testing with the standard grips on their personal drivers. Each test subject hit three golf shots with each of the JumboMax Tour Series and UltraLite grip sizes, using a TaylorMade 10.5-degree driver with a graphite stiff-flex shaft.
The eight grip sizes included:
- Standard (Baseline Data)
- Standard Oversize (SO)
- Standard Jumbo (SJ)
- Extra-small (XS)
- Small (S)
- Medium (M)
- Large (L)
- Extra-large (XL)
Grips were changed from smallest to largest after each three-swing collection. FlightScope was used to gather data, which were averaged for three-shot sets.
Fourteen of 15 test subjects demonstrated an increase in clubhead speed compared to baseline. The average increase in swing speed was 3.65 mph.
Test subjects demonstrated an increase in carry distance compared to baseline. The average increase in distance was 12.68 yards.
There is little disagreement that golf grips are important as the connection between the golfer and the golf club. They can, however, be overlooked by golfers who may undervalue the impact of the golf grip on their performance. Noll (2022) stated that the wrong way to play with golf grips is if they are worn out (i.e., slippery, misshapen). From that point, the best golf grip for players is the one in which they believe feels and looks best to them.
JumboMax claims that its oversized grips positively affect golf performance, which in this study was determined by clubhead speed and carry distance. Industry commentary and the data in this informal study confirm this claim.
Though generalizations cannot be made concerning golfers’ improved performance, this study makes a firm statement that oversized grips should, at the very least, be included in club fittings as a principal variable for consideration in the development of golfers’ most effective bag of clubs.
