JumboMax STR8 Tech Non-Tapered Putter Grip Tour Series, Medium (+5/16") StabilityCore Oversized

JumboMax STR8 Tech Non‑Tapered Grip (Tour Series, Medium +5/16") is an oversized, anti‑hook putter grip designed to stabilize hands and promote a smoother, more consistent putting stroke.

Engineered for golfers who want improved face awareness and steadier tempo without squeezing harder, the STR8 Tech Tour Series puts an emphasis on counter‑balance, stability, and comfort. This single‑pack, medium‑sized grip adds +5/16" to the standard butt diameter and features JumboMax’s non‑tapered profile and StabilityCore construction for twist resistance. It’s compatible with popular shot‑tracking sensors, and the ergonomic shape encourages lighter hand pressure for longer practice and better control.

How does this grip reduce hooking and face rotation?

The STR8 Tech uses an oversized lower hand area and counter‑balanced weight distribution to limit unwanted face rotation during the stroke. That larger contact zone decreases the tendency to force the putter face closed, helping it stay more square through impact.

• Oversized lower hand area minimizes excessive wrist motion.
• Counter‑balanced added weight stabilizes the putter head.
• Non‑tapered profile enforces uniform hand placement for consistent face control.

What stability benefits does the StabilityCore deliver?

StabilityCore is a twist‑resistant internal structure that reduces torque at impact so the putter face tracks truer to the line. That construction helps produce repeatable roll and a steadier feel without sacrificing feedback.

• Twist resistance improves consistency on off‑center hits.
• Solid feel that enhances feedback for fine adjustments.
• Tour‑inspired performance aimed at repeatable stroke mechanics.

Will the shape and size change my grip pressure and comfort?

The super‑oversized, ergonomic shape promotes a lighter grip pressure by spreading contact across a broader surface, which reduces hand tension and fatigue during long sessions. Many players report improved comfort and longer practice windows when switching from standard tapered grips.

• Ergonomic form encourages relaxed hands for smoother tempo.
• Medium (+5/16") thickness balances control and feel for most golfers.
• Available in Tour Series finish for a sleek, performance‑focused surface.

Is this grip compatible with tracking sensors and other putter types?

Yes—JumboMax designed the STR8 Tech to be tech ready; it accepts Arccos and CobraConnect sensors for data‑driven practice. The non‑tapered design also fits a wide range of putter shafts and hosel styles when installed by a club builder or qualified fitter.

• Sensor compatibility: Arccos and CobraConnect ready.
• Fits common putter shafts with standard installation procedures.
• Single‑pack option lets you try one head‑to‑head before changing all putters.

Who is this for? The JumboMax STR8 Tech Non‑Tapered Grip (Tour Series, Medium +5/16") is aimed at golfers seeking greater face control, reduced wrist action, and a steadier putting tempo. It suits players who favor oversized, non‑tapered grips—especially those practicing longer sessions, switching to counter‑balanced setups, or using shot‑tracking tech. If you want to limit hook tendencies, encourage lighter grip pressure, and add measurable stability to your stroke, this grip is a practical upgrade.
