A lot of the timing sets that aren't of Japanese manufacture don't have the links properly indexed. A lot of guys won't use the non-Japanese kits to replace their timing chains, gears, tensioners and adjusters.
I used a DNJ kit on mine about 45K miles ago. Will it last as long as the OEM Japanese kits? Probably not. But then I also don't expect the engine to last another 150K without a slight head gasket leak or be in need of a rebuild or replacement.
If I had owned my Tracker since new and I knew the service history, I'd be far more finicky about it and would have opted for the Japanese manufactured timing kits. About $50 more in price. As it is, my truck was rode hard and put away wet for its first 81K of life. I knew this when I bought him. I worked on getting the internal engine cleaned using Sea Foam, kept regular oil changes, filter changes and perform the maintenance and replacement of components as required, but I have no illusions he will still be running strong at 250K. If he does... great. If he doesn't, I won't really be surprised.
Buster will hit 200K within a couple weeks. He still runs great (knock on wood) but he has developed a leak in the rear crank seal (I believe) which requires about a half pint of oil about every two weeks. Not a critical fluid loss, but I don't like my stuff to leak at all. It isn't cost effective (to me) to pull the tranny and fly wheel in order to attempt a repair of this seal. Especially since the engine has 200K on it and this small leak began shortly after I replaced the clutch (of course!).
