Hearing a rattle from the front of your Lexus or Toyota V8 engine, especially on a cold start? Could be a worn timing chain or tensioner. This AUCERAMIC full timing chain kit is a comprehensive solution. It fits a range of vehicles from 2008-2019 with the 1UR-FSE 4.6L V8 or 2UR-GSE 5.0L V8 engines. That includes Lexus GS460, GX460, IS F, LS460, LS600h, and Toyota Sequoia and Tundra models. The kit is seriously complete: it has both upper (secondary) and lower (primary) timing chains (2 of each), four tensioners (upper left/right, lower left/right), four guide rails (fixed and tensioner types), and two crank sprockets (inner and outer). It's built to meet or exceed OEM standards, using durable materials for quiet, long-lasting operation. Replaces a bunch of OEM part numbers like 135070P010 and 13561-0S040. This is a major job best left to experienced mechanics, but if you're tackling it, having all the components in one box is a lifesaver. A quality aftermarket kit that can restore your engine's quiet, precise timing and prevent catastrophic failure.
