KIT K3341

This is a comprehensive O‑ring kit for rebuilding the air‑operated shift‑range cylinder on Eaton Fuller manual transmissions.

Use this kit when you notice air hissing from the shift valve or experience delayed/incomplete range changes. It is a direct aftermarket replacement for the OEM Fuller K‑3341 kit.
