  • 1-3/8 inch Bore: Lower operating pressure than standard 1 inch bore units
  • 5/8 inch Piston Rod: Heavy-duty nitrocarburized rod for long service life. On non-dust shield units only
  • Resistance and arc-welded mounts, provide a 9,000 lbs. (4,082 kg) tensile strength for maximum durability (on most applications)
