The Grafalloy ProCustom Par Iron Shaft in A/L (Senior/Ladies) flex is the ultimate graphite iron shaft for custom club builders who need the versatility to fit a wide range of golfers. Engineered as a lightweight, low-flex graphite shaft, it delivers a higher ball flight, smooth feel, and consistent performance — making it an ideal choice for seniors, ladies, and slower swing-speed players. Whether you are a professional club fitter or a passionate golfer building a personalised set, the ProCustom Par delivers reliability and adaptability in every iron from 3-iron through pitching wedge.
The ProCustom's A/L combination flex means a single uncut shaft can be trimmed to produce either an A (Senior/Amateur) or L (Ladies) flex — simply by varying the amount of tip and butt trim applied. This gives club fitters maximum inventory efficiency and eliminates the need to stock two separate shaft models for different player types. Every shaft in a set can be individually dialled in through the manufacturer's trim chart, ensuring each iron is precisely matched to the player's requirements. The result is a cohesive, performance-consistent set from 3-iron through pitching wedge, all built from the same uncut shaft.
Grafalloy's proprietary System 9 software calculates up to 100,000 new data points with every design change — modelling frequency, tip deflection, balance point, swing weight, torque, and EI profiles simultaneously. Rather than relying on trial-and-error prototyping, every Grafalloy shaft is engineered with mathematical precision before a single material is laid. This means the ProCustom Par delivers exactly the intended flex, launch, and feel characteristics across every shaft in the set, with no variability between individual units. System 9 is the reason Grafalloy shafts are trusted by both custom club builders and Tour professionals worldwide.
The carefully positioned low-to-mid bend point encourages the clubhead to release smoothly through impact, launching the ball on a mid-to-high trajectory. This translates into greater carry distance and a steep enough descent angle for soft-landing approach shots — a key benefit for players who struggle to get the ball airborne with heavier, stiffer shafts. The A/L flex profile is specifically calibrated for slower swing tempos, ensuring the shaft loads and unloads at precisely the right moment in the downswing for maximum energy transfer at impact. Seniors, ladies, and juniors will immediately notice the effortless height and carry the ProCustom Par generates.
The 0.370" parallel tip is the most common iron hosel diameter in the industry, meaning the ProCustom Par drops straight into the overwhelming majority of iron heads on the market — from cavity-backs to muscle-backs. Club builders can trim each shaft to the exact length and flex required for every iron in the set using the manufacturer's trim chart, with the 41" tip trim window providing generous adjustment range. The parallel tip also ensures a consistently stable epoxy bond and secure seating in the hosel, reducing the risk of shaft movement over time. This universality makes the ProCustom Par the single most inventory-efficient graphite iron shaft a custom builder can stock.
