Penn Slammer 4 4500 Hs Spinning Reel is packed with more features than ever before. Building off of our proven IPX6 sealed body and spool, we redesigned our Slammer® drag system to not only be better sealed, but also offer a wider range of usable drag, all while being bearing supported for extra smoothness. Adding our all-brass CNC gear technology, 8+1 stainless steel bearing system, and Hydrophobic Line Roller Bearing has made the Slammer IV the ultimate workhorse reel.
