We calculate two different types of 3-point correlators involving twist-2 operators in the leading weak coupling approximation and all orders in N-c in N=4 SYM theory. Each of three operators in the first correlator can be any component of twist-2 supermultiplet, though the explicit calculation was done for a particular component which is an SU(4) singlet. It is calculated in the leading, Born approximation for arbitrary spins j(1),j(2),j(3). The result significantly simplifies when at least one of the spins is large or equal to zero and the coordinates are restricted to the 2d plane spanned by two light-rays. The second correlator involves two twist-2 operators Tr(X del X-j1) + ..., Tr(Z del(j2)Z) + ... and one Konishi operator Tr[(Z) over bar, (X) over bar](2). It vanishes in the lowest g order and is computed at the leading g(2) approximation.
