Piper Strut Thread (Typical and Maximum Number of Threads)

As permitted for rigging

Per the Super Cub Owner’s manual, to obtain correct dihedral: “…the correct dihedral will be obtained when about seven threads on the lift strut adjustment forks are exposed. (A maximum extension of threads is permissible.)”

7 threads exposed (approx.) when rigged correctly.

15 threads exposed for maximum permissible extension.

This information is applicable for J-3, J-4, J-5 and PA-11 through PA-22.
