A: Yes! This 4-piece set includes adapters suitable for use on both positive and negative battery posts. They feature a universal feed-through design that works with a wide variety of standard battery types and clamp sizes.

Q: Do I need any special tools to install these battery terminal shims?

A: No special tools are required. Simply slide the shim adapter onto the battery post, then attach your cable clamp as you normally would. The adapter fills any gap and ensures a snug, stable fit for a reliable electrical connection.
