Turbo Quad Black Bowling Ball Finger Insert

Your release is the only variable left. Everything else is already dialed.

Finger inserts do not make the shot. They stop being the thing that loses one.

Dual-Sided Control: Side one is a Perfect Oval that mirrors the natural curve of your fingertip for a neutral, comfortable seat. Flip to the Power Lift 1/4" side when you want extended loft and a cleaner breakaway.

Tournament-Proven Design: Turbo has been the default pick for serious grip work across every major league. This insert is not an experiment. It is the baseline.

Sized to Match You: Precision fractional grip sizes covering 19/31 to 13/16 at 31/32" diameter and 53/64 to 29/32 at 1 1/32" diameter. Pick the fit that disappears in your hand.

Sold Individually: One insert per order. Replace exactly what you need, when you need it. You are not paying for nine spares you will never touch.

Clean, Fast Installation: Smooth bonding surface, flat seating edge, true geometry. Glue it in and stop thinking about it.

Stop compensating for hardware. Put the right insert in and bowl the shot you already own.
