Which Golf Shafts and Clubs Can Be SST PUREd?

Nearly every golf shaft can be SST PUREd: graphite and steel, stock and aftermarket, cut or uncut, in drivers, fairway woods, hybrids, irons and wedges. The main exception is some bent-neck putter shafts.

Shafts

Shaft type	Can it be PUREd?	What to know
Graphite	Yes	Including stock and aftermarket graphite shafts
Steel	Yes	Straightness, roundness and the weld seam in steel shafts all affect how they behave
Stock	Yes	Limited exceptions such as some bent-neck putter shafts
Aftermarket / premium	Yes	Even premium shafts have measurable structural characteristics; SST PURE evaluates each shaft individually
Cut or uncut	Yes	Any shaft, cut or uncut, can be PUREd, marked and installed
Used or pulled	Yes	If it is suitable for reuse; a qualified builder should inspect it for damage
Previously PUREd	Yes, if needed	A PUREd shaft without its alignment line may need to be PUREd again and remarked

Independent Testing: Plugged In Golf

Plugged In Golf measured 36 randomly selected steel and graphite iron shafts on an SST PURE system. Both materials benefited: off-plane oscillation improved 75.2% on average for graphite and 64.7% for steel, and there was no correlation between flex and the amount of improvement.

Clubs

Club	Can it be PUREd?	What to know
Driver	Yes	Golf Laboratories robot testing covered drivers. See results
Fairway woods	Yes	Choose your adjustable adapter setting first
Hybrids	Yes	Same adapter rule as woods
Irons	Yes	Steel and graphite; robot testing covered 6-irons
Wedges	Yes	When the shaft and club use standard shaft installation
Putters	Many	Some bent-neck putter shafts are an exception; a licensee can confirm

Independent Testing: Plugged In Golf

Putters: in Plugged In Golf’s putter test, results were mixed. A few testers improved impact location and consistency, but there was no distance benefit on mishits. Their conclusion: PUREing a putter shaft “definitely won’t hurt your performance, but you may not see any improvements either.” The benefit is clearer in full-swing clubs.

Should I PURE every shaft in my iron set?

PUREing every shaft in a set means each shaft is analyzed and installed in its own measured stable orientation, which is the most complete way to address shaft orientation from club to club. Whether to do the full set is a value decision, but it is the best way to get consistency through the bag.

Can matching shafts need different orientations?

Yes. Two shafts of the same model and flex can need different rotations to reach their stable orientation, because structural characteristics vary from shaft to shaft. That is why SST PURE analyzes each shaft individually instead of assuming one ideal logo position.

Adjustable clubs

If your driver, fairway wood or hybrid has an adjustable hosel, some settings rotate the shaft. Pick the setting you will play before PUREing. Read the adjustable driver guide.
