This is a new #4 draw length module set for Darton two cam bows equipped with the Magnesium Alloy High Energy Wheels. The High Energy Wheel eccentrics were used on Darton bows from the early 1980's to early 2000's. Some of the bows that were offered with these include the Excel, SL Hunter, SuperStick, Apache, Scout, Viper, Raider, Tempest, Trailmaster, Ranger, Mustang, Falcon, Laredo and many others. Actual draw length provided by this set ultimately depends on bow model, string and cable lengths, etc. This set is new or swapped from a new bow at purchase.
