Maule Anti-Shimmy Connector

Add to Wishlist
Part# 06-15150
MFR Model# 4001-29


A high and low frequency spring is used to upset the natural frequency of the tailwheel. The lighter spring is used on the left side.


I had one of the small Tailwheel spring clips pull open on my Extra 300. This is the prefect replacement system with the oval clips with safety cotter pins.

Works great to stop the shimmy on the Scott 3200 tailwheel on my CUB

Could have been suppied with slightly longer pieces of chain, too short for my aircraft.

Was wanting to put these on a Taylorcraft with a maule tail wheel. The distance between the tail wheel an the rudder arm was to short.

One of the connecting links was not drilled to accept the cotter pin. I simply drilled it out to make it work but it is a pain to do.

This will only work I your chains are kept in constant tension.
