PEAK offers replacement heads that allow you to convert your JS1 product to a JS2 product or your JS2 product to a JS1 product. The #1 has the largest LIRS head and holds the largest hooks. The #2 is the smaller LIRS head of the Jurassic products and holds hooks between the JS1 and the PRVLIRS (the smallest of the LIRS heads).

• Increase the range of hook sizes you can tie on without buying a complete new vise.
• If you own a JS2, you can purchase the JS1-HD and swap those heads in and out.
