Built to Lock In. Balanced by Design.
 
This isn’t just a neck conversion – it’s a full re-engineering of balance and motion.
Our COG-Balanced Flip Neck Conversion is designed to intersect the putter’s true center of gravity and create a stroke that naturally stays square through impact. By flipping a left-hand plumber’s neck into a right-hand setup, we align the face, lie, and weight distribution in a way that delivers a straight-back, straight-through roll without forced timing.
 
Ideal for players who want a more automatic stroke, this setup reduces torque and eliminates over-rotation – perfect for those who leave the face open or over-close at impact.
Finished in our Anti-Glare Tour Blast and welded by Rush Kane, this mod delivers both precision and playability worthy of a tour build.

WHY COG-BALANCE MATTERS
 
Most players think they need face balance – what they really need is true center-of-gravity alignment.
 
When the hosel is flipped and positioned to the COG, the putter naturally squares to the target without manipulation. The result?

✅ Straighter path control
✅ Consistent energy transfer
✅ More predictable roll
 
Perfect for:
Straight-back, straight-through strokes
Players seeking less face rotation
Those who prefer visual linearity at address
 
Rush Kane is one of the few builders who offers this level of balance customization through hosel geometry.
 
With our Signature Plumber’s Neck, you’re not locked into a fixed design – this mod is fitted to your stroke, your stance, your goal.
