Closely mirrors Stellar's friction-module, piston-kit, and overhaul-kit portfolio for transmission rebuilders across domestic and import vehicles.

• Schaeffler Group: Schaeffler supplies transmission components, clutches, and aftermarket parts globally under brands like LuK and FAG. Adjacent incumbent with overlapping OE and aftermarket transmission-part coverage at substantially greater scale.
