Blackheart Crossbow String Tenpoint 31.56in.

The Blackheart Crossbow String Tenpoint 31.56in. is a precision-engineered replacement string purpose-built for TenPoint crossbow systems. After years in the field, any serious crossbow hunter knows that the bowstring is the heartbeat of consistent, reliable performance—it transfers energy to the bolt, absorbs recoil, and determines accuracy shot after shot. This 31.56-inch Blackheart string is designed to restore factory performance and maintain the tight tolerances your TenPoint platform demands for ethical, accurate hunting.

Blackheart strings are crafted using a proven blend of modern high-performance materials and time-honored bow-building techniques that prioritize durability and consistency. The signature GlideLock center serving reduces friction at the nocking point, minimizes serving separation over countless shots, and virtually eliminates the ridges that form between serving wraps on inferior strings. This refinement keeps your nock fit consistent, your arrow flight true, and your groups tight across extended hunting seasons. The lightweight construction at just 0.15 lbs ensures minimal mass at the string interface, preserving the energy transfer and arrow velocity your TenPoint crossbow was engineered to deliver.

This string is ideal for hunters running a TenPoint platform who have logged serious hours in the field and recognize that string wear accelerates with use and exposure to elements. Replacement becomes critical when serving shows separation, when nock fit loosens, or when draw weight feels inconsistent—all signs that energy transfer has degraded. Simply measure your current string or verify your TenPoint model's factory spec against the 31.56-inch length to confirm fit. Installation requires no special tools; secure the string loops to both limb tips and verify proper alignment before drawing. Keeping a backup Blackheart string on hand ensures zero downtime when the season is at its peak.
