This is the pin that holds keeps the pull-up line guide (whiz rod) in place. If you have broken your Whiz rod make sure you still have the pin!
Fits standard Smart Track rudder housings: Original, Compact, Race, which use two pins; Ski & Flow housings use one.
Price is for one pin. (Whiz rod sold separately)
Note on Fitting - It is a force fit (carefully!) - work it in. It will seem like the pin is too big but in reality it is the friction between the pin and the Whiz rod that holds it in place.
