904 Aluminum Multi-Spring Retainer Kit


904 Aluminum Multi-Spring Retainer Kit.

The original 904 return spring is wound the wrong way so at higher RPMs, the spring collapses.  This allows the piston to come out, causing drag on the clutches.  This multi-spring kit eliminates the movement by stiffening the pressure applied to the piston.  This also helps the 2-3 shift timing.
