Product Description
Keep your pro shop fully stocked with a ten-pack of the Turbo Switch Grip NX Inner Sleeve with 1 1/4" Urethane Slug — the removable half of Turbo's next-generation thumb insert system, pre-loaded with a 1 1/4" 100% urethane thumb solid ready to drill and fit. Each sleeve in this bulk pack is engineered with oversized Dual-Winged Tabs and an all-new Dual Snap™ Locking System, creating greater surface contact with the matching Outer Sleeve for enhanced stability, a stronger connection, and an unmistakable locked-in feel shot after shot.
With the 1 1/4" urethane slug already in place on every sleeve, your pro shop can drill each one directly to a bowler's thumb size without needing a separate solid — saving a step during fitting. This 10-pack is the best value option for busy pro shops, giving you the lowest per-sleeve cost and enough inventory on hand to handle a full day of fittings using the same standard thumb solid size without reordering.
Note that the Switch Grip NX Inner Sleeve features larger, redesigned locking tabs than the Original Switch Grip® and is only compatible with the NX Outer Sleeve — it will not lock into the original Outer Sleeve.

Turbo Switch Grip NX Inner Sleeve with 1 1/4" Slug Installed 10 Pack FAQ
What's included in this 10-pack?
This pack includes ten Switch Grip NX Inner Sleeves, each pre-installed with a 1 1/4" 100% urethane thumb solid ready to be drilled to size.
Is the 10-pack a better value than the 5-pack or single sleeve?
Buying the 10-pack typically offers the lowest per-sleeve cost of any 1 1/4" Inner Sleeve option, making it the most economical choice for pro shops that fit this slug size regularly.
Is this Inner Sleeve compatible with the Original Switch Grip Outer Sleeve?
No. The NX Inner Sleeve has larger, redesigned locking tabs that only fit the Switch Grip NX Outer Sleeve, and is not cross-compatible with the original line (Turbo Grips NX installation video).
How is this different from the 1 3/8" slug version?
Both use the same Dual-Winged Tabs and Dual Snap™ Locking System and lock into the same NX Outer Sleeve. The difference is thumb solid size — this version has a 1 1/4" urethane slug, which fits smaller thumb dimensions than the 1 3/8" option.
Do I still need the Outer Sleeve separately?
Yes. Each Inner Sleeve in this pack requires a Switch Grip NX Outer Sleeve, sold separately and permanently installed in the thumb hole, to complete the assembly.
Should I drill and fit these myself?
Drilling the Outer Sleeve hole and finishing the pre-installed solid to final thumb size should be done by a qualified pro shop technician for the best fit and durability.
What colors is this Inner Sleeve available in?
The Switch Grip NX Inner Sleeve is available in Black and Red.
