Engine couplers may need to bechanged based on the transmission and application. In general spring plate couplers are used for inline or co-axial transmissions, and dual-stagecouplers for V-Drive and Down-Angle transmissions. If using on an existing engine, a new coupler is recommended when using a new transmission.
Also, please be sure to install and properly adjust new premium shift cables as the #1 clutch failure is from improperly adjusted shift cables that canresult in severe transmission damage. Propshaft couplers need to be sourced separately.
