This is an EXCELLENT gasket set from very high quality material. I've purchased others that are extremely thin and like paper until I found these. I maintain about 10 different Xterra's, Pathfinder's and Frontier's in the family, all with the VQ40 and have done about 6 timing repair jobs. Very glad someone else is producing these with such high quality material. HIGHLY recommend purchasing these if you're doing your timing chains.
