About the Cleveland 588 Forged MB

The 588 Forged MB is the muscle-back blade at the top of Cleveland's 2013 588 iron range, precision forged from 1025 carbon steel and named for the classic 588 wedge. The tour-inspired profile carries a thin topline, compact head and minimal offset for workability, with Tour Zip Grooves and laser milling on the face for spin. Lofts are traditional throughout — 35 degrees at the 7-iron and 47 at the pitching wedge. The set was sold 3-iron through pitching wedge with True Temper Dynamic Gold as the stock steel shaft, and the range also included a combo option mixing the MB short irons with the 588 Forged CB cavity backs.

Frequently asked questions

What is the loft of a Cleveland 588 MB 7-iron?

The Cleveland 588 Forged MB 7-iron has a loft of 35 degrees, a lie of 62 degrees and a length of 36.75 inches.

Are the Cleveland 588 MB irons forged?

Yes — each head is precision forged from 1025 carbon steel, with Tour Zip Grooves and laser milling on the face.

What is the difference between the Cleveland 588 MB and 588 CB?

They share the same lofts, lies and near-identical lengths, but the MB is a pure muscle back for shot-makers while the CB adds a progressive cavity, a slightly longer blade, thicker topline and marginally more offset. Cleveland also sold a combo set mixing CB long irons with MB short irons.

Finding a used set

The Cleveland 588 Forged MB ran from 2013 to 2015 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
