1994-1996 Impala SS Timing Chains

During a camshaft swap it is a good time to change out your factory timing chain. For most daily-driven and mild camshaft applications, we recommend the GM "LT4" Timing Set. For more aggressive engines, we have the GM "Extreme Duty" Timing Set. The Extreme Duty timing set is by far the stronger setup of the two, however, some additional noise may be encountered when going with this item.

When building a high-output engine, you do not want to have excessive slack in the timing chain because it affects the overall accuracy of the valvetrain. We have noticed that in most LT1 and LT4 applications, there is large amounts of slack in the timing setup from the factory. Even when going with the GM Extreme Duty set, many times we have encountered more slack in the timing chain than we would like. To compensate for this, we have found an oversized crank sprocket which will tighten up the setup enough to reduce timing chain slack to an acceptable level.
