ROYMADE putter weights for Newport putter Style 2pcs 30g weights, matched pair with O-rings for swing weight tuning

ROYMADE replacement putter weights: a pair of precision-balanced 5g–45g weights engineered to retrofit many Newport and Studio Select putters for custom feel and head mass adjustment.

These two aftermarket weights give you a simple way to tune the swing weight and stability of compatible Newport-style putters. Sold as a matched pair, each weight comes with a protective rubber O-ring and is available in eight discrete masses—5g, 10g, 15g, 20g, 25g, 30g, 35g, 40g and 45g—so you can experiment with head balance without buying a new club. Construction uses lighter aluminum alloy for the smallest option, stainless steel for mid-range masses, and dense tungsten for heavier options to keep size compact while increasing mass.

Which putters will these ROYMADE weights fit?

They are designed for many Studio Select and Newport family models. The set fits Newport, My Girl, California (including 2012), ButtonBack, Select GoLo, Select Mild & Long, Kombi, Futura X and many limited or tour variations that share the same recessed weight cavity.

• Compatible with most Studio Select model putters
• Works with Newport-style head cavities
• Not compatible with Squareback, Fastback, Detou, or Newport Select M1/M2 series
• Sold as a matched pair (2pcs) for balanced tuning

How do material choices affect feel and performance?

Smaller weights use aluminum alloy to minimize size and cost, mid-range weights use stainless steel for durability, and the heavier pieces are tungsten for maximum mass in a small package. The denser materials let you add significant head weight without enlarging the hardware, preserving head geometry and center of gravity.

• 5g: aluminum alloy — lightest option for minimal change
• 10–20g: stainless steel — durable, moderate mass
• 25–45g: tungsten steel — high mass in compact form
• Choose weight to fine-tune head speed and moment of inertia

How do I install and protect the weights in my putter?

Installation is straightforward: remove the existing weight with the appropriate wrench and replace it with the ROYMADE unit, making sure the included O-ring seats properly before tightening. The rubber seal keeps moisture and grit out of the cavity, reducing corrosion risk and ensuring a snug fit that won’t rattle during play.

• Includes protective rubber O-rings for moisture resistance
• Requires a compatible weight wrench for removal/installation
• Seat the O-ring fully before tightening to avoid leaks and noise
• Use matched pair to preserve putter balance left-to-right

Can these weights be used for custom fitting sessions?

Yes — because they’re offered in small, incremental steps across a wide range of masses, these weights are useful for testing feel and roll during fitting. Swapping weights lets you quickly evaluate changes in swing weight and forgiveness without altering shaft or grip setup.

• Fine increments allow controlled testing of feel and tempo
• Small physical size (esp. tungsten) keeps head geometry unchanged
• Useful for on-course trials or in-shop fitting sessions
• Sold as pairs to maintain left-right balance during testing

Who is this for? These ROYMADE replacement weights are intended for golfers, club fitters, and DIY tuners who use Newport or Studio Select-style putters and want a cost-effective way to adjust head mass and balance. They suit players experimenting with swing weight or seeking to restore a misplaced or worn factory weight, provided their putter shares the compatible recessed weight cavity. Note: check your model before buying — these do not fit Squareback, Fastback, Detou, or the Newport Select M1/M2 series.
