Spec Racer differential nuts (pack of two) are replacement fasteners that secure the differential in SR aluminum hub setups for the 22 3.0 SR platform. This two-piece pack provides a snug, dependable fit during operation and makes routine maintenance or rebuilds straightforward.

These nuts are designed specifically for SR aluminum diff hubs and are not compatible with standard 22 steel outdrive ball differentials. The two-nut pack offers a convenient, ready-to-use replacement for keeping the Spec Racer 22 3.0 SR configuration securely assembled and performing as intended.
