Katech C5-R Timing Chain Set Kit with 3-Bolt Cam Sprocket, Crank Sprocket, Dampener & ARP Cam Bolts
Complete Timing Upgrade Kit for 58X LS Engines (2007–2013) | Fits 4.8L, 5.3L, 6.0L, 6.2L
This complete timing upgrade kit combines the legendary Katech C5-R Racing Timing Chain with a GM 3-bolt (4-pole) cam sprocket, crank sprocket, LS2-style timing chain dampener, and ARP 134-1003 cam bolts. Engineered for GM 58X LS engines (2007–2013), this kit delivers unmatched reliability, strength, and timing stability—ideal for camshaft upgrades, performance builds, and higher-mileage engines. The centerpiece is the Katech KAT-7636 racing chain, known for its superior tensile strength and flawless record in C5-R endurance racing. This kit replaces failure-prone factory components while ensuring accurate valve timing and long-term durability across demanding LS applications.
Key Features
- Katech C5-R High-Strength Timing Chain: Authentic KAT-7636 chain (formerly HME-G68V-2) built with superior tensile strength for maximum longevity, accuracy, and durability. Proven in Katech C5-R and C6-R racing programs and never broken in durability testing.
- GM 3-Bolt Cam Sprocket (58X): Required when converting from a 1-bolt camshaft to a 3-bolt cam. Designed for 58X reluctor engines and works with all LS engines except LS7/LS9. Uses production sprockets for an OEM-style fit.
- Stock Replacement Crank Sprocket: Direct-fit lower timing chain gear that ensures proper alignment and compatibility with LS timing assemblies (except LS7/LS9).
- LS2-Style Timing Chain Dampener: Reduces chain whip and increases chain life. Replaces the failure-prone spring-loaded LS tensioners. Not compatible with LS1, LS6, or 2006-earlier truck blocks.
- ARP 134-1003 Cam Bolts: Premium fasteners with superior preload and clamping force to maintain precise cam gear register and resist valvetrain harmonics. A must-have for performance builds.
Key Fitments
- Engine Compatibility: Fits 2007–2013 GM Gen IV 58X LS engines, including 4.8L, 5.3L, 6.0L, and 6.2L configurations used in trucks, SUVs, and performance vehicles.
- Camshaft Conversions: Ideal for converting a 1-bolt LS camshaft to a 3-bolt camshaft design while upgrading all major timing components simultaneously.
- Performance & Service Builds: Perfect for cam swaps, valvetrain upgrades, high-mileage refreshes, or any performance LS build requiring greater timing accuracy and durability.
