Our BulletProof Corrosion Resistant Pins are precision machined from our patented stress-proof steel. They are a necessary complement to any BulletProof Hitch or accessory and have been designed to ensure strength, durability and utility. The corrosion-resistant pin features an electroless nickel undercoat with a zinc plating topcoat for unsurpassed corrosion resistance. Many northern states have a high concentration of calcium chloride or 'salting' on the roads leading to rapid corrosion on standard coatings. The dual-plating process of the corrosion-resistant pin is designed to protect the integrity of the pin, ensuring strength for many years to come. These pins will be supplied/sold as a pair with two R-clips included, and rated to the full capacity of any BulletProof Hitch. Useable length of 4" *PATENT PENDING
