Which Lexus models have a timing chain?
Most Lexus models in the current lineup use timing chains instead of timing belts.
Across recent generations, Lexus has leaned on chain-driven timing for its gasoline engines across sedans, SUVs, and hybrid variants. If you’re evaluating a specific model-year, verify the exact engine code to confirm the timing method, as there can be market-specific variations or rare exceptions.
Model-by-model overview
Below is a broad overview by major Lexus model families, highlighting the typical timing-chain setup on their engines.
Sedans and coupes
- Lexus ES
- Lexus IS
- Lexus LS
- Lexus RC
- Lexus LC
Note: In these passenger-car lines, the engines have traditionally used timing chains, reducing belt-related maintenance concerns for most owners.
SUVs and crossovers
- Lexus UX

Note: The SUV and crossover lineup continues to rely on chain-driven timing in the mainstream engines offered in current generations.
Summary
Bottom line: For most buyers, nearly every current Lexus model uses a timing chain in its engine. This includes the majority of sedans and crossovers, with chains generally offering longer service intervals and fewer belt-related maintenance concerns. Always check the exact engine specification for a given year and market, as there can be rare variations on non-standard models.
