Core Sensor 3 & 4 Bar Inserts – Product Description

The Core Sensor 3 & 4 Bar Inserts are genuine replacement inserts designed specifically for the Sensor 3, Sensor 3+, Sensor 4, and Sensor 4+ control bar systems. These inserts play an essential role in protecting your depower line and ensuring smooth, friction-free bar travel. Over time, inserts naturally wear from saltwater, sand, and repeated sheeting, so replacing them with genuine Core Sensor 3 & 4 Bar Inserts restores your bar’s precision, safety, and longevity.

Built from a durable, low-friction composite material, the Core Sensor 3 & 4 Bar Inserts help maintain the clean, effortless sliding motion Sensor bars are known for. When bar inserts become worn, riders may experience rough sheeting, increased wear on the depower line, or reduced bar performance. These genuine CORE inserts return your bar to factory-smooth operation and prevent premature line damage.

Compatible with both Sensor 3 and Sensor 4 generations, these inserts are easy to install, corrosion-resistant, and engineered to handle the toughest marine conditions. For riders who frequently kite in heavy wind, surf, or sandy environments, replacing inserts regularly is essential for keeping your bar running safely and efficiently.
