Katech LT/LS C5.R Timing Chain

Katech LT/LS C5.R Timing Chain

C5.R-Proven Timing Control for LS and LT Engines

Developed through Katech’s long-standing involvement in professional endurance racing, the Katech LT/LS C5.R Timing Chain has demonstrated exceptional durability and reliability. 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.

This 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.

The 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.

Compared 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.

Each genuine Katech LT/LS C5.R Timing Chain is laser-engraved with the Katech logo for positive identification. This marking identifies the chain as a Katech-exclusive component supplied directly by Katech Engineering and through authorized distribution channels.

Features & Benefits

• C5.R-Proven Durability: Developed from Katech’s involvement in professional endurance racing programs and engineered for sustained high-RPM and endurance operating conditions.
• Production-Style Replacement Design: Designed for use with compatible production timing sprockets, which are not included.
• No Oil Pump Clearancing Required: Does not require oil pump clearancing when used with a production-style oil pump, unlike many double-roller racing timing chains.
• Enhanced Fatigue and Wear Resistance: Incorporates fine-blanked chain plates and a Katech-specified proprietary pin coating.
• Timing Stability: Designed to maintain dimensional stability and consistent camshaft timing during sustained high-RPM operation.
• Authenticity and Traceability: Laser-engraved with the Katech logo for positive identification as a genuine Katech-exclusive component.

Technical Overview

The Katech LT/LS C5.R Timing Chain is engineered for compatible LS- and LT-based engines retaining production-style timing geometry. The design prioritizes strength, dimensional stability, and precise camshaft timing control for applications using aggressive camshaft profiles, increased valve-spring loads, and sustained high-RPM operation.

By maintaining production-style chain geometry, the timing chain provides proper engagement with compatible crankshaft and camshaft sprockets while avoiding the oil pump clearance concerns commonly associated with double-roller timing chain conversions.

Important: Proper installation, sprocket compatibility, and timing verification are critical. Professional engine assembly is strongly recommended.
