About the Maltby KE4 Max
The KE4 Max sits at the forgiving end of Maltby's long-running KE4 line, cast from 17-4 stainless with an extremely thick topline, a wide sole and generous offset built for maximum forgiveness rather than shot-shaping. The GolfWorks' own Maltby MPF ratings chart dates it to 2022 with an MPF of 959 - Maltby's own "Ultra Game Improvement" tier - and the company advertises the model as carrying the strongest lofts in its premium iron range: a 30-degree 7-iron and 43-degree pitching wedge across a 4-GW factory chart, with a matching 48-degree gap wedge. A 4-way radiused sole varies bounce and sole width by club for turf interaction across lofts, and a vertical centre of gravity of 0.758 inches keeps launch high through the set. Sold as bare heads or built-to-order paks (commonly 4-PW or 4-GW) through The GolfWorks, with custom loft and lie available at no charge on professionally assembled sets; a separate KE4 MAX-F forged model shares the name but uses a different, forged construction.

Where it sits in the lineup
Introduced in 2022, the Maltby KE4 Max is a current super game improvement set in the Maltby range, with no replacement announced. New sets are built to the standard lofts, lies and lengths in the chart above, though a fitting can move any of them — so confirm the numbers on the order sheet. Used sets appear on eBay, 2nd Swing and Golf Avenue, and should be measured against this chart before buying.

- GolfWorks Maltby MPF Ratings chart (golfworks.com/content/PDFs/Head_MPFs/MPFRatingsChart.pdf, retrieved July 2026) — 'MALTBY KE4 Max #6 2022, MPF 959', fixing year_introduced 2022.
- The GolfWorks product description copy (p/ma0337/, p/cma0337/) and Ralph Maltby Q&A ('KE4 Max vs TS3', 'Differences between KE4 Tour+ vs KE4 Max') — the cast (not forged) 17-4 stainless construction, the 'Ultra Game Improvement' positioning as the most forgiving model in the KE4 family, extremely thick topline and wide sole, 4-way radiused sole with progressive bounce, 0.758-inch vertical CG, and the separately-sold KE4 MAX-F forged sibling that should not be confused with this cast model.
- The GolfWorks 'Standard Lengths' chart (golfworks.com/content/description/standard-playing-lengths.png, linked from the same product page) — men's steel iron lengths of 38.5 (4-iron) down to 35.5 inches (PW/GW), used here because Maltby sells this head component-style and does not publish a model-specific length column.
