Product Description
Keep your pro shop stocked with a five-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 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 5-pack is a smart way to buy in bulk and save on a per-sleeve basis, keeping your bench stocked for a steady flow of fittings using the same standard thumb solid size.
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 5 Pack FAQ
What's included in this 5-pack?
This pack includes five Switch Grip NX Inner Sleeves, each pre-installed with a 1 1/4" 100% urethane thumb solid ready to be drilled to size.
Why buy the 1 1/4" Inner Sleeve in a 5-pack instead of individually?
Buying in a 5-pack lowers your per-sleeve cost and keeps your pro shop stocked for multiple fittings without reordering after every job — ideal for shops that regularly fit bowlers with this standard slug size.
Is this Inner Sleeve compatible with the Original Switch Grip Outer Sleeve?
No. The NX Inner Sleeve features larger, redesigned locking tabs that only fit the Switch Grip NX Outer Sleeve. Bowlers switching to NX need to replace both the Inner and Outer Sleeve in every ball, since the two generations are not cross-compatible (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.
