Sonnax conversion spacer GMBW-WS-40 and outer stator race GM-R-15 are used with the GM 300mm outer stator race, springs and rollers for a cost-effective upgrade to BW 310mm LU (A618), GM TH400 (3L80), AT-540 and Buick TH350 stator clutch assemblies. The upgrade repairs and improves the performance of OE stator cams with problematic roller clutch design.
