*The same coupling is used on both the driver's seat and passenger seat.
Proper Parts has re-engineered an improved design that ensures a smooth slip fit to the seat motor and transmission. The D-shaft openings are very accurate. It is 1.46" long (37 mm).
We manufacture these couplings from a urethane chosen for its hardness and toughness while still having good flexibility. When the seat comes to the end of its track there is no cushion, and this coupling allows the motor to slow down gradually, ensuring a longer life for all of the components involved. It is much better than the original.
If your coupling is yellowing or shows any sign of cracking when held up to the light, we recommend replacing it.
