Blackheart Crossbow String 40.875 In. Horton Storm Rdx & Tenpoint Nitro Rdx

The Blackheart Crossbow String 40.875 In. Horton Storm Rdx & Tenpoint Nitro Rdx is engineered for hunters who demand reliability and consistency from their crossbow setup. This replacement string is specifically designed for two of the industry's most popular modern crossbows, making it an essential maintenance item for serious hunters who rely on their equipment season after season. Proper string maintenance directly impacts accuracy, safety, and the longevity of your crossbow investment.

Blackheart strings are constructed using a precision blend of high-performance materials and time-honored bowstring techniques that withstand the extreme forces generated by modern crossbows. The GlideLock center serving significantly reduces friction and serving separation—two of the most common failure points in crossbow strings—while virtually eliminating ridges between serving strands that can cause erratic arrow flight and reduced lifespan. At 40.875 inches, this string length matches factory specifications exactly, ensuring proper draw weight and brace height when installed correctly. The lightweight design (0.15 lbs) minimizes any impact on your crossbow's balance and performance characteristics.

Hunters using Horton Storm Rdx or Tenpoint Nitro Rdx crossbows will find this Blackheart string a direct fit requiring no modification or adjustment beyond standard crossbow string installation procedures. Regular string replacement—typically every two to three years depending on usage frequency—keeps your crossbow performing at factory specifications and maintains accuracy for hunting applications ranging from whitetail to elk. Proper installation by a qualified crossbow technician ensures safe operation and maintains any existing warranty coverage on your equipment.
