About the TaylorMade rac OS
The rac OS was the oversize, most forgiving member of TaylorMade's rac iron family. The rac name stands for relative amplitude coefficient, a vibration-management approach that routes impact energy into shaped Feel Pockets in the back of the head. A repositioned Tuned Performance Cartridge saves 32 grams that is moved to the perimeter, and the head pairs an ultra-thin face and deep cavity with generous offset. The 7-iron is 33 degrees and the stock range runs from a 2-iron to a 60-degree lob wedge. Specs below are the men's standard steel-shaft build.

Frequently asked questions
What is the loft of a TaylorMade rac OS 7-iron?
The TaylorMade rac OS 7-iron has a loft of 33 degrees, with a 63-degree lie and a 36.75-inch steel-shaft length.
What does rac stand for on TaylorMade irons?
rac stands for relative amplitude coefficient. It is TaylorMade's method of managing impact vibration by directing energy into shaped Feel Pockets in the back of the clubhead rather than letting it spread in all directions.
What is the pitching wedge loft on the rac OS?
The rac OS pitching wedge is 45 degrees, with a 50-degree approach wedge, 55-degree sand wedge and 60-degree lob wedge available in the set.
Finding a used set
The TaylorMade rac OS ran from 2003 to 2005 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
