Product Details

The 7/16-20 x 2.000 inch Perma-Loca stud girdle from ARP is a well-built component designed to reinforce your connecting rod bolts. Its .750 inch body diameter is engineered to provide a solid anchor point, helping to prevent flex and maintain consistent clamping force on your rod bolts under high stress. This is a crucial piece for any engine build that expects to see significant power and RPMs.

ARP is known for making strong engine components, and this stud girdle is no exception. It’s made from durable materials and designed to work with ARP's Perma-Loca stud system. By tying the rod bolts together, this girdle helps distribute the load more evenly, reducing the strain on individual bolts and improving the overall reliability of your rotating assembly. This can be particularly important in performance applications where stock components might not hold up to the increased demands.

When you're building an engine that needs to perform, attention to detail in the rotating assembly is key. This stud girdle is a smart addition to help ensure your connecting rods and bolts stay put, even when you're pushing the limits. Make sure you have the correct ARP Perma-Loca studs to pair with this girdle for a complete and secure setup.
