This Katech KAT-7636 (Formerly HME-G68V-2) timing chain for the GM Gen III/IV/V LSx engine is manufactured to a higher tensile strength for greater accuracy and longevity. This is the same chain used in the C5-R and C6-R racing engines built by Katech. We recommend replacing your factory chain with this upgraded version when doing camshaft installations or other modifications where the chain is easily accessed, especially on higher mileage engines.

To verify the authenticity of a Katech Chain see the logo on the Chain Link in pictures. Others selling imitation Katech chains will not have this logo on them.

Never broken in all of C5-R racing and durability testing, this easy replacement utilizes production sprockets.
