JRS Archery Strings strives to find the most stable and consistent materials for our bow strings. Our custom bowstrings are the result of years of extensive research and development. Our research has helped us discover which material is best for every application. This results in better strings that last longer and are more durable. Each string is tailored to your specific bow model. You will get a smoother draw for every shot and a better back wall. We will never use cheap alternatives to all of the new and innovative materials available. Although we don't offer ready-to ship strings, they are all pre-stretched with several hundred pounds tension. Pre-stretching your strings eliminates creep and peep rotation when you use your bow. Our strings are less time-consuming than taking hundreds of shots to get your bow string fully settled. Instead, it takes just 20 shots for the string to settle. You won't need to constantly adjust your bow and retiming it because all of the stretch has been removed.
