Lexus LX 570 Timing Chain – No Belt, Lifetime V8 Chain
The 3UR-FE V8 uses a dual-row oil-lubricated timing chain — no timing belt ever. Chain stretch is essentially non-existent with regular 5W-30/0W-20 oil changes. The LX V8 chain is one of the most durable in any Lexus model.
LX 570 Timing Chain
The LX 570 3UR-FE 5.7L V8 uses a timing chain system. Like all Toyota/Lexus V8s, the chains are designed for engine life. The 3UR-FE has two sets of chains and is extremely robust. Use 5W-30 full synthetic, change every 10,000 km. At very high mileage (180,000 km+), primary chain tensioner and chain guides can wear — symptoms are extended cold-start rattle. Preventive inspection during major engine work is worthwhile on high-mileage LX.
