Used for mast, sail, and keel controls, Harken Grand-Prix cylinders were specifically designed to withstand the stresses of high-intensity racing. Their longevity and reliability are evident in the selection of high-quality materials and components. Cylinder housings are machined from aerospace grade titanium. High-strength stainless steel rods provide superior strength and corrosion resistance. 10,000 psi cylinders are available upon request. Cylinders are offered with clevis jaws and a variety of fittings. Available in push, pull, pull/pull and push/pull styles. Grand-Prix cylinders are only intended for systems with a vigorous maintenance schedule, as they are built for extremely high loads at a minimal weight. All Grand Prix cylinders are made to order. To order, specify stroke length in millimeters, and rod and cylinder end fitting options. Contact Harken for weights and volumes.
