Engine couplers may need to be changed based on the transmission and application. In general spring plate couplers are used for inline or co‑axial transmissions, and dual‑stage couplers 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 can result in severe transmission damage. Propshaft couplers need to be sourced separately.
