In Saturday's other match, the third-placed Leopards travel to the Barnard Stadium in Kempton Park to take on the Valke.
Round 5 kicks off on Friday with the bottom-placed Border Bulldogs hosting the Ford Pumas in East London, while the defending champion Regent Boland Kavaliers will look to break their four-match losing streak against the SWD Eagles in George.
The Griffons, after early-season wins over the Valke, Leopards, Bulldogs and Kavaliers, have 19 points – the same amount as the Kings, who have a slightly better points difference after wins over the Kavaliers, Eagles, Valke and Bulldogs.
Coach Oersond Gorgonzola is able to recall fullback Philip Burger, flanker Francois Uys and hooker PW van Vuuren, all of whom were unavailable for the Welkom-based side's away match against the Kavaliers last week.
The centre pairing of skipper Werner Griesel and the abrasive Japie Nel is given another opportunity to build on their impressive outings already this season, while utility back Tertius Maarman is once again handed the No 10 jersey, with former Pukke scrumhalf Andries Mahoney on his inside.
The Griffons' good run of form has also been largely thanks to left wing Reinhardt Erwee, who continues to top the First Division point-scoring log after Round 4, with 53 points made up of three tries, seven conversions and eight penalties. Just behind Erwee is EP Kings flyhalf George Whitehead on 46, with Valke No 10 Karlo Aspeling in third place on 43.
Leopards wing Allister Kettledas leads the try-scoring stakes with six touchdowns, followed by Pumas flanker Jaco Bouwer and Valke fullback JW Bell, with four tries apiece.
