The SWX-Z mods allow you to maximize your Mathews performance for each draw length, ensuring optimized experience in the field. Compatible with 2024 and newer Mathews hunting models (those utilizing the SWX cam), the SWX-Z mod offers a new option within Mathews’ SwitchWeight Technology, that provides a more generous draw force curve to produce an ultra-smooth draw with a modest tradeoff in peak speed ratings. Specifications: Draw Length Range: 23.5” – 33.5” (depending on bow model) Let-Off: 85%
