This is a battery terminal adapter designed to convert a side-terminal battery to accept standard top-post style cable clamps, or vice versa.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It provides a solid threaded stud (often 3/8-inch) that lets you securely bolt on accessory wiring for equipment like snow plows, lift gates, or winches. Over time, original battery terminals can corrode or wear out, causing poor electrical connections and starting problems; replacing or adapting them with a brass or lead adapter restores a tight, reliable connection and helps prevent future power loss.
