CruzTOOLS (SP58-4) 5/8" x 4" Long Spark Plug Socket
Proper adjustment of shock sag can have a substantial impact on handling and comfort, yet few riders ever make the adjustment. It's quite simple and quick, but you'll need a shock spanner to set preload. Our spanner is made of tough stainless steel, and is compact enough to fit inside your tool kit. It's designed to fit most major makes of shock absorbers.
