Set 262 to win on the third and final day in Beckenham, the tourists reached their target in 57.1 overs with England spinner Shoaib Bashir recording second-innings figures of 0-45 from eight overs after bagging 4-76 from 20.2 first time around.
Bashir is hoping to be included in the England XI in Leeds next week, live on Sky Sports, but the hosts could pick an all-pace frontline attack with the recalled Dan Lawrence, who will bat at No 6, and newly reappointed captain Joe Root providing the spin options.

Opening batter Emilio Gay and seam bowler Matt Fisher were the other members of the England Test squad, besides Bashir, to play in Beckenham, although the first two were released from duty on the final day.
Gay bagged a pair in the match as the home side made scores of 305 all out and 195 all out, while Fisher clubbed 62 not out from 53 balls in the hosts' first innings before registering bowling figures of 1-15 from 11 overs in Pakistan's opening knock of 238.
Who else impressed for Pakistan in Beckenham?
Pakistan's top-scorer in their first innings was Abdullah Shafique (61), while highlights with the ball included a second-innings five-for for left-arm spinner Ali Usman.
The tourists suffered a scare on day two when captain Babar Azam retired hurt after being struck on the hand by a delivery from young Hampshire quick Manny Lumsden.
Babar was advised to rest for the remainder of the game but a PCB statement said he would train at Headingley on Monday.
The skipper said on Saturday after the win over the County Select XI: "It's a very good preparation for us to prepare ourselves for the Test.
"The pitch was a bit challenging early on but it got better after a couple of days. We have to prepare ourselves for the game and it's a great thing to go out and perform.
"I'm not sure what the conditions will be like in the first Test, but seeing here it's slightly dry and the ball was turning as well. That pitch will have some bounce there.
"It will be slightly different [in Leeds]. We will be preparing accordingly. "
