Salman Mujtaba Autos reports supplying this assembly with the separate AISIN CST-008 clutch disc / pressure plate set for the locally used Grande manual application. CST-008 identifies the separate clutch set; it does not establish release-cylinder fitment for every vehicle. The product supplied here is the China-made RSB-marked release assembly.

Catalogue references place 31400-59015 in the release-cylinder family later serviced by Toyota 31400-59025. This is an aftermarket part carrying the earlier reference. Match the original part number or a confirmed equivalent, gearbox, mounting pattern, installed height, hydraulic connection and bleeder arrangement before ordering, particularly where the vehicle specifies the later service part. Engine size or the Grande badge alone does not confirm compatibility.

Clutch disc and pressure plate are separate products.
