Top Post Adapter - Negative
KnuKonceptz Top Post Adapter can be fitted to either our Bassik or Ultimate Battery terminal. The TPA allows the installer to retain the OEM battery post hardware. No Cutting or modifying required.
Please note, the NEGATIVE POST can not be substituted for a POSTIVE POST. The post diameters of the postivie and negative terminal are not the same and you will not be able to tighten your OEM battery terminal onto this post.
