Replacement for the wear part drive belt in short version.
Bringt more power transmisstion but also higher wear out and losses...
Used as a slip clutch, the EPDM ages belts in the winch.
If not enough power can be transmitted, then the belt should be replaced.
It is always recommended the standard belt, but in special cases it may make sense to use the "short" version, with an increased power transmission is possible, but then the slip properties of the electric spring action are limited and he comes to a higher wear.
