N233943  supersedes older part numbers: N275023

Genuine DeWalt return spring (part no. N275023) — a direct replacement spring for the magazine/pusher assembly on DeWalt cordless nailers.

Made from hardened steel with a shot‑peened finish to resist fatigue, it restores proper tension to the pusher and ensures smooth, reliable nail feeding and return action when the original spring is worn or broken.

Example fitment includes DeWalt DCN45RN / DCN45RNN and the DCN920 / DCN930 framing nailer and DCN920B, DCN920P1, DCN930B, DCN930P1 — confirm the model number and type to confirm fit.

Supplied as a single original DeWalt part (sometimes listed as a replacement for part N233943), it installs in the return/pusher area per the tool service instructions and gets a tired magazine feeding system working like new.
