Scarlets include Wales Six Nations squad members Ellis Mee, Joe Roberts, Kemsley Mathias and Taine Plumtree for the resumption of BKT United Rugby Championship action against Munster at Thomond Park on Saturday (17:15).
In all, there are five personnel changes from the home victory over Edinburgh in January.
In the back three, Mee comes onto the right wing, with left wing Steff Evans and full-back Ioan Nicholas retaining their spots.
Roberts partners Johnny Williams in midfield, while Ioan Lloyd again links up with scrum-half Gareth Davies.
Davies captains the side in the absence of Josh Macleod, who sits out the game with a slight hamstring issue.
In the front row, Mathias packs down alongside Marnus van der Merwe and Archer Holz.
Max Douglas gets the nod in the second row alongside Sam Lousi, while in the back row Plumtree (pictured) is selected at blindside and the fit-again Dan Davis at openside. Vaea Fifita wears the No. 8 jersey. Davis makes his first appearance since Bayonne in early December.
Further fitness boosts are provided by the return from injury of Wales international hooker Ryan Elias and prop Sam Wainwright, who are named among the replacements.
Head coach Dwayne Peel said: “We know that Thomond Park is a tough place to go, but we are excited by the challenge. You want to be prepared for a fight when you go there, that is a mindset thing for us. We can’t allow Munster to dictate the pace like two years ago (in Cork) when they blew us away in the first half hour before we clawed our way back.
“Take the Gloucester game out of it and we have been competitive when we have travelled this season, but lost some tight games. We lost to Glasgow by two points, we lost to Bayonne by one point, we lost to Ospreys by one point. We want to turn that tide.”
