[ALIBI]

We have been using timing belts from McMaster-Carr in our drivetrain for years and have never had a failure, check the specs., they keep getting stronger and stronger ratings. We have used slots for tensioning (transmission/CIMS slide back and fourth). Belts do require more work to replace, we just have never had to. We have a four wheel drive 06' (kit tranny w/ two cims each driving 8' wheels) with four belts that are still original with no sign of wear. On short runs I would recommend timing belts, longer runs are probably better served by chains.
