Premium 1-Piece PTFE Rear Main Crankshaft Seal w/Housing Gasket - Fits Chevrolet Silverado 1500 Tahoe GMC Sierra 1500 Yukon 4.8L 5.3L 6.0L 1999-2020 & More

Keep your GM truck or SUV running dry and reliable with this premium 1-piece PTFE rear main crankshaft seal (with included housing gasket) from LowPricedAutoParts – the trusted retailer of automotive parts and accessories dedicated to outstanding customer service. This high-quality seal is precision-engineered for the popular GM 4.8L, 5.3L & 6.0L Vortec V8 engines in 1999–2020 models including Chevrolet Silverado 1500, Tahoe, Express 2500/3500; GMC Sierra 1500, Yukon, Savana 2500/3500 and related full-size trucks, SUVs & vans. These Vortec V8s are favorites for their massive low-end torque, impressive towing capability & proven durability – powering millions of work trucks, family SUVs, fleet vans & daily drivers with widespread parts availability and straightforward maintenance. Over time, the original rear main seal can wear or harden, allowing oil to seep past the crankshaft and create drips, low pressure warnings or messy bellhousing areas. This premium PTFE 1-piece replacement effectively resolves those issues, restoring secure sealing and peace of mind for continued heavy use. PTFE construction offers exceptional low-friction performance, superior heat resistance & outstanding compatibility with engine oils, while the integrated housing gasket ensures a complete, leak-free install. As a direct-fit upgrade, it maintains proper crankshaft alignment and engine cleanliness during transmission swaps, clutch service, oil pan gasket replacement or full engine rebuilds on these robust Vortec powerplants. Installation is straightforward for experienced mechanics: Thoroughly clean the crankshaft flange and block housing, inspect for grooves or damage (consider polishing or repair sleeve if needed), apply light assembly lube or GM-approved sealant, position the seal/housing assembly carefully without distortion, torque bolts evenly in sequence to factory specs, and monitor closely during initial startup and break-in. Professional assistance is recommended for precise alignment or if measurements raise questions. At LowPricedAutoParts, customer service is our top priority.
