Never broken in all of C5-R racing and durability testing, this easy replacement utilizes production sprockets (not included). This is the exact timing chain used on the Corvette Racing C5-R, C6.R and C7.R race cars from 1997-present in the ALMS and now United Sportscar series. Also such endurance races as the 24 Hours of Le Mans and 24 Hours of Daytona. The C5-R race chain gets proprietary features over the standard IWIS aftermarket LS chain which includes "fine blanked plates" and a proprietary pin coating. This is the only chain you'll ever need, and since it fits over production sprockets its a direct replacement with no worries of clearance to your oil pump.
This IWIS timing chain for the GM Gen III/IV LSx engine is manufactured to a higher tensile strength for greater accuracy and longevity. These are the same chains used in the C5-R and C6-R racing engines built by Katech. Thunder Racing recommends replacing your factory chain with this upgraded version when doing camshaft swaps or other modifications where the chain is easily accessed, especially on higher mileage engines. |
