Description
Precise Engine Timing. If your engine won’t start or starts backfiring, you may need to inspect your sprocket timing gears to see if they are faulty. These sprockets are important in your engine’s operation as it regulates valve and ignition timing. Upgrade now and replace your rusty old sprockets with the Vintage Crankshaft Sprocket. It lets you prevent backfires and keep your Jeep in working condition with a brand-new crankshaft sprocket.
Stop the Rattling Engine Noise. Another symptom that your sprocket or timing gear may need changing is the noise that’s coming from your engine. This could indicate that the timing chain is hitting something in your engine that it’s not supposed to. Restore the proper turning of your timing chain with a new Vintage Sprocket. Installing this new sprocket will prevent further damage to other parts of your engine and will stop its annoying rattling noise.

The company offers a comprehensive 12-month or 12,000-mile product warranty to assure customers they are getting a top-of-line product.
