New Heineken Cup favourites Munster need a solid victory to firm up their playoff hopes and Gaffney has named a full-strength side.
Ronan O'Gara will lead the way with the boot, while a powerful backrow of skipper Jim Williams,
David Wallace and Anthony Foley will test Treviso's defence.
The in-form Frankie Sheahan lines up at hooker, while Ireland coach Eddie O'Sullivan will be keeping a close eye on the form of the likes of centre Rob Henderson and lock Paul O'Connell.
Munster: S Payne; J Kelly, M Mullins, R Henderson, A Horgan; R O'Gara, P Stringer; G McIlwham, F Sheahan, J Hayes; D O'Callaghan, P O'Connell, J Williams (capt), D Wallace, A Foley.
