Product Description
Katech C5-R LS Timing Chain Kit with 3-Bolt 58X Cam Sprocket
Fits Select 2007-2013 4.8L, 5.3L, 6.0L & 6.2L LS Engines | C5-R Chain, 3-Bolt Cam Gear, Crank Sprocket & ARP Cam Bolts
Upgrade your LS timing system with the Katech C5-R Timing Chain Kit. Built around the Katech KAT-7636 C5-R timing chain, formerly part number HME-G68V-2, this kit combines a high-tensile-strength timing chain with a 3-bolt 58X cam sprocket, stock-replacement crank sprocket, and ARP cam bolts. The C5-R chain is the same design used in Katech C5-R and C6-R racing engines and is a strong choice during camshaft installations, timing service, engine rebuilds, and higher-mileage LS upgrades. This kit is designed for compatible 2007-2013 4.8L, 5.3L, 6.0L, and 6.2L LS engines using a 3-bolt camshaft configuration.
Key Features & Benefits
- Katech C5-R Timing Chain: Includes the Katech KAT-7636 C5-R timing chain, engineered with increased tensile strength for dependable timing control, accuracy, and longevity in compatible Gen III and Gen IV LS applications.
- Race-Proven Chain Design: This is the same timing chain design used in Katech C5-R and C6-R racing engine programs, making it an excellent upgrade during camshaft installations and major timing system service.
- 3-Bolt 58X Cam Sprocket Included: Includes a 3-bolt 4X timing gear for converting a compatible 1-bolt camshaft setup to a 3-bolt camshaft configuration when used with the correct 3-bolt camshaft.
- Stock-Replacement Crank Sprocket: Includes a lower timing chain gear designed as a stock-replacement option for compatible LS engines, excluding LS7 and LS9 applications.
- ARP Cam Bolts Included: Includes ARP cam bolts engineered with increased material strength and preload clamping force to help maintain positive timing gear register under valvetrain load and operating stress.
