JumboMax Grips can quickly and dramatically improve the way you play the game of golf.

In head-to-head testing by Golf Etc. of America, and GolfTest USA, golfers increased their driver carry distance by an average of 10 yards, reduced slice spin, increased ball speed, improved launch angle and gained accuracy.

JumboMax® Grips are designed to fit your hands better for more solid ball striking. Our Finger-Palm™ technology places the grip in the strongest, most stable part of your hand while promoting a relaxed grip on the club for a more fluid and powerful swing.

JumboMax Grips eliminate tension for faster clubhead speed. Golf instructors universally agree that the fastest way to ruin a good golf swing is by gripping the club too tightly, or by increasing grip pressure during the swing, which prevents the club from releasing at impact. Our Finger-Palm technology instantly gives you a more secure hold on the club, so you don't feel the need to squeeze. You'll relax your grip on the club freeing your hands and arms to release the club naturally, giving you the fluid, effortless and powerful swing you need. You'll find it easier to keep the clubface square longer through impact for straighter, more powerful shots.

How do JumboMax compare to standard grips?

The golf industry does have a standard for measuring grip sizing on non-putter grips. Measuring 2" below the grip end cap, the diameter of the grip is recorded.

The following chart compares the diameter 2" below the grip end cap for various grip sizes.

Play and practice longer with less shock on your joints.

JumboMax Grips outperform standard grips for distance and accuracy and have the added benefit of being extremely shock-absorbing. If you experience pain during or after golf or have arthritis, you will really appreciate our super-oversized, shock absorbing technology.

Yes, these grips are for you.

From novices to advanced players, everyone can benefit from the secure, yet relaxed grip provided by JumboMax Grips. They will quickly and dramatically improve the way you play the game of golf adding to the enjoyment of your game.

    No more pain!

    Posted by Jason on 14th Feb 2018

    Golfers with weak grips, arthritis, joint pain or other conditions that make it hard to grip a golf club can benefit from these larger grips.
    Because the grip is larger it will better absorb the shock of impact or a mis-hit, which means less stress for golfers with arthritis or other conditions.
    I purchased one grip to test and using the handy grip replacement guide fixed it to my driver. From the first tee the change was instant, more confidence, better feel and no grip pain.
    The trajectory, or flight path of the ball, is affected by a player's ability to grip the golf club properly. If you cannot properly hold a standard grip you may consistently hit balls that slice (fade right) or hook (fade left) because the club is either incorrectly positioned in your hands or is moving at impact. Using an oversized grip will help eliminate this problem by allowing you to have a firmer grip on the club.
    The added weight also gave me a few more yards so you will need to watch or relearn your yardage.
    I have Ankylosing Spondylitis, it restricts my swing and I was hitting the driver 210 sometimes 230 easily 10 to 20 yards shorter than my playing partner. Last Sunday I was out driving him, the proof is there to see.
    I recommend the JumboMax Tour Series 3/8, these are deeply textured, ultra-tacky, all weather that promotes even grip pressure that you will love.
    I don’t work for AdoreGolf so trust me when I say contact and after care is something important to me, with that in mind my next order of 10 grips was delivered within two days, they are honest about their stock levels and won’t take your money and then you have to wait three weeks for delivery like some other grip suppliers. Communication from order to delivery was quick and educated which is rare these days.
