The Steelmen have won 8 of eleven games this term - the best record in the league so far - and are out-performing champions-elect Neath and second-placed Newport.
Llanelli defeated the Black and Ambers 27-13 a fortnight ago and will be hoping to reproduce that performance against the leaders tomorrow (SAT).
Second and third go head to head at Rodney Parade as NEWPORT play host to champions NEATH.
The Welsh All Blacks are the form team going into this fixture having defeated Cardiff 27-19 in their last outing.
And Rowland Philips' outfit will be looking to the real All Black's demolition of Wales last week to inspire them to close the gap at the top of the table.
Newport meanwhile will be keen to make amends for their loss to Llanelli and prove they have what it takes to go the distance in the title race.
Fourth-placed ABERAVON take on BEDWAS at the Talbot Athletic Ground with their eyes set on the top three.
The Wizards are level on points with Neath in third and a win would ensure they too remain in contention for honours at the end of the season.
Mid-table Bedwas saw off Bridgend 15-11 last time out and will look to rise to the challenge of Aberavon on Saturday.
The bottom two clash at the Memorial Ground as GLAMORGAN WANDERERS and LLANDOVERY go head to head.
The Wanderers are two points adrift of Llandovery at the foot of the table and this fixture is a true six-pointer.
Victory is a must for the Wanderers if they are to avoid being cast adrift while the Drovers must also win if they are to remain in touch with the teams above them.
BRIDGEND and PONTYPRIDD meet at the Brewery Field on Saturday with the sides level on points in the table, 10 points behind leaders Ebbw Vale.
Both teams have looked off-colour this season and will likely both admit they are not where they would like to be in the table.
A win on Saturday could push one side into the mix at the top while defeat could signal the end of any title ambitions.
Elsewhere, CROSS KEYS and SWANSEA play at Pandy Park and CARDIFF travel east to take on MAESTEG.
