Hi,
In HikaShop, if you enter the dimensions for a product in the HikaShop backend product page ; the dimensions will be displayed in the front-end.
It is displayed by the view "show_block_dimension" which is loaded by the product page ( "show_default" ) and display under the product price.
There is nothing else to do and it is not depended of a "stock template" (and I don't know what is a "stock template" is).
