How many distance irons can say they have their own sound engineer? With an improved Speed Bridge and ECHO Damping System for better sound and forged-like feel, TaylorMade went further than they thought possible to bring you a distance iron that feels better than anyone thought possible. A more refined Speed Bridge puts SIM Max a step above its predecessor, and the ECHO Damping System expands across the entire face from heel to toe, giving you forged-like feel in a distance iron. The new SIM Max irons have a 17% thinner face than the previous class, increasing ball speed and forgiveness. The Thru-Slot Speed Pocket completely disconnects the lower portion of the face from the sole of the iron and allows for a free-floating face. When combined with Speed Bridge, the face maintains stability while delivering maximum ball speed. If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard TaylorMade warranty applies and satisfaction is guaranteed.
