The Kyosho 74019-15-1 Back Plate Set is a direct replacement part manufactured for KE21 and KE25 engines. It restores the rear sealing surface and keeps internal alignment consistent for smoother running.
Designed specifically for KE21 and KE25 units, this back plate ensures the correct fitment and helps preserve original engine tolerances. It is not a universal component and should be matched to the listed engine models.
Before fitting, make sure mating faces are wiped clean and any gasket material is removed. Hand start all fasteners and tighten evenly to avoid distortion of the back plate or crankcase.
