Product Description
Genuine Lempco S-289 Timing Sprocket (NORS)
The Lempco S-289 is a New Old Replacement Stock (NORS) crankshaft timing sprocket designed exclusively for a wide range of Chevrolet Truck V8 engines from 1957 to 1984. This essential component ensures precise synchronization of your engine's camshaft and crankshaft, critical for optimal valve timing and engine performance. It is specifically noted for heavy-duty applications in Chevrolet trucks.
Visual Condition:
Upon visual inspection, the timing sprocket exhibits areas of surface rust, particularly on the outer teeth and some flat surfaces. This is typical for vintage NORS parts that have been stored for decades and does not affect the structural integrity or functionality of the component. The keyway and inner bore appear clean and ready for installation after a light cleaning.

Note on Stock Photos: Due to our inventory of multiple identical units for this specific part number, we utilize representative stock photos for this listing. You will receive a component that strictly meets all listed specifications and fitment requirements. Please be aware that because these are vintage parts, minor cosmetic variations—such as surface finish, color, or production markings—may exist between different manufacturing runs. These slight aesthetic differences are a result of historical production processes and do not impact the part's integrity, performance, or authenticity.
A Note on Fitment Accuracy: We manually research our fitment data using vintage manufacturer catalogs to provide you with the most accurate information possible. However, because we are human and these decades-old resources can occasionally contain errors, we cannot guarantee 100% accuracy. We strongly encourage you to perform your own due diligence and verify this part number for your specific application before purchasing. Please note that this part may also fit other vehicles or years not explicitly listed in our research.
