Dometic 21 Foot Xtreme Rack Cable, Steering Cable SSCX15421

The Dometic Xtreme Rack Cable (SSCX15421) is a 21 foot rack-and-pinion style steering cable engineered for reliable, consistent helm response on board. As part of the Xtreme Rack Cable lineup, it connects the helm to the outboard or sterndrive steering system, transmitting steering input through a sealed rack housing designed to resist the corrosion and wear common in marine environments. This cable is sized specifically at 21 feet, making correct length selection important when ordering a replacement for your existing steering run. Boat owners and marine technicians use this cable to replace a worn, stiff, or leaking rack cable and restore smooth, predictable steering feel at the helm. The unit ships as a single exterior cable assembly ready to be installed into a compatible rack and pinion steering system.
