The combo kit includes the rear Works-Z sprocket and a Sunstar front sprocket made of case-hardened chromoly steel. The combo includes your choice of chain, however, the Sunstar 520 XTG Tripleguard compliments the sprockets and as a threesome take the rigors of riding far longer than any chain and sprocket combination available.
