Product Description
Get the strongest, most secure thumb connection yet with the Turbo Switch Grip NX Outer Sleeve — the next evolution of Turbo's popular interchangeable thumb insert system. Engineered with oversized Dual-Winged Tabs and an all-new Dual Snap™ Locking System, the Switch Grip NX Outer Sleeve creates greater surface contact between the inner and outer assemblies for enhanced stability, a stronger connection, and an unmistakable locked-in feel shot after shot
The Outer Sleeve is the permanent half of the Switch Grip system — it gets glued directly into your bowling ball's thumb hole by your pro shop, while the removable Switch Grip Inner Sleeve carries your actual thumb fit and can be swapped between balls in seconds. No more taping and re-taping your thumb hole every time you switch equipment. Just twist, click, and bowl with the same comfortable fit, whether you're moving from a heavy-oil ball to a dry-lane ball or dialing in your thumb size as it swells or shrinks throughout the day.
Best of all, Switch Grip NX maintains the same drilling instructions and assembly diameters as the Original Switch Grip®, so pro shops can install it with the same 1 1/2" outer diameter drill bit and drilling process bowlers already trust — no new tools, no learning curve, no starting over. The Outer Sleeve is fully compatible with Switch Grip NX Inner Sleeves in both 1 1/4" and 1 3/8" urethane options.
Whether you're building your first interchangeable thumb setup or upgrading from the Original Switch Grip, the Turbo Switch Grip NX Outer Sleeve delivers a more secure, repeatable fit for serious league and tournament bowlers who demand consistency from ball to ball.

Turbo Switch Grip NX Outer Sleeve FAQ
What is the Turbo Switch Grip NX Outer Sleeve used for?
The Outer Sleeve is the permanent half of the Turbo Switch Grip NX interchangeable thumb insert system. It's glued into your bowling ball's thumb hole by a pro shop and stays there permanently, while a removable Inner Sleeve carries your actual thumb fit and can be swapped between different bowling balls.
How is the Switch Grip NX different from the Original Switch Grip?
Switch Grip NX features newly engineered, oversized Dual-Winged Tabs that create greater surface contact between the inner and outer assemblies, plus an all-new Dual Snap™ Locking System for a stronger, more secure connection and a more noticeable locked-in feel than the original design.
Can I use my Original Switch Grip inner sleeves with the NX outer sleeve?
No, they are not compatible. Switch Grip NX maintains the same drilling instructions and assembly diameters as the Original Switch Grip®, so the drilling process is unchanged. For the best locked-in feel and full benefit of the Dual Snap Locking System, pairing the NX Outer Sleeve with NX Inner Sleeves is necessary.
What size drill bit does the Switch Grip NX Outer Sleeve require?
The Outer Sleeve installs with the same 1 1/2" outer diameter Switch Grip drill bit used for the Original Switch Grip, keeping the drilling process consistent for pro shops already familiar with the system.
Can I install the Switch Grip NX Outer Sleeve myself?
Installation requires drilling a properly sized thumb hole and permanently gluing in the Outer Sleeve, so it should always be done by a qualified pro shop technician using the correct drill bit and adhesive to ensure a secure, centered fit.
What colors is the Switch Grip NX Outer Sleeve available in?
The Switch Grip NX Outer Sleeve is available in Black and Red.
