These ​custom crossbow bow strings​ for the XB400 by Mankung are the best that you can buy! These strings meet the exact string requirements for your XB400 and deliver ultimate performance, zero creep, and no serving separation. America's Best Bowstrings only uses the finest BCY fibers in the manufacturing of our crossbow strings combined with the most advanced string building technologies, which results in a string that is unmatched in quality and performance. Our strings utilize our ​exclusive ​Ultra End Loops​ to deliver long lasting durability along with a perfect fit.
