FEL-PRO BS 40640 Engine Crankshaft Seal Kit for Chevrolet Silverado 1500

Customers find the crankshaft seal kit to be of high quality, easy to install, and effective at preventing oil leaks. The product fits well, with one customer noting it's perfect for a 5.3L engine, and customers consider it good value for money. The seal quality receives mixed feedback - while some say it's similar to the original GM seal, others report the rear main seal feels loose.
