Across documented Corvette Racing programs and internal durability testing, no timing chain failures have been recorded, supporting its use in demanding LS- and LT-based racing and high-performance applications.\u003c\/p\u003e \u003cp\u003eThis timing chain design was derived from and utilized in Corvette Racing C5.R-based programs, with applications spanning the C5.R and C6.R eras. It has been proven in top-level endurance competition, including the 24 Hours of Le Mans and the 24 Hours of Daytona.\u003c\/p\u003e \u003cp\u003eThe Katech LT\/LS C5.R Timing Chain is a direct replacement designed for use with compatible production timing sprockets, which are not included. Unlike many double-roller racing timing chains, this design does not require oil pump clearancing when used with a production-style oil pump, supporting straightforward installation in high-performance and endurance engine applications.\u003c\/p\u003e \u003cp\u003eCompared with standard aftermarket IWIS-style timing chains, the Katech C5.R Timing Chain incorporates proprietary enhancements, including fine-blanked chain plates and a Katech-specified proprietary pin coating. These features improve fatigue resistance, wear characteristics, and long-term timing stability under sustained high-RPM operation.\u003c\/p\u003e \u003cp\u003eEach genuine Katech LT\/LS C5.R Timing Chain is laser-engraved with the Katech logo for positive identification.
