There are two additions in the backs, with call-ups for Fijian winger Timoci Nagusa and Ravens regular Tommy Seymour.
Ulster ended a run of six matches without a league win when they ran in five tries for a 37-25 victory over Edinburgh last time out, thus securing their place in next season's Heineken Cup.
Ulster coach Brian McLaughlin will want his charges to finish the campaign on a high against Connacht.
He has a strong squad to pick from, with Bryn Cunningham, Matt McCullough, Justin Fitzpatrick, Mark McCrea, Cillian Willis and David Pollock the players unavailable due to injury.
