LSx Adjustable Timing Set:

Infinitely Adjustable from 6° Advanced or Retarded
Heat Treated Machined Steel Billet Gears
Roller Thrust Bearing for Minimal Friction

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.

This is the original equipment timing chain for all LS1, 6, 2 & GEN III applications.

This double roller high performance timing chain kit is a perfect complement to your high performance valve springs and other LS- Gen III/IV engine components.  It offers greatly enhanced strength and accuracy compared with the stock piece and even allows for timing adjustments (advance or retard) of up to 8 degrees.  The set contains an adjustable nine keyway billet steel crankshaft sprocket with a Torrington thrust bearing, two oil-pump spacer plates, and detailed instructions.
