Keep your classic Chevrolet or GMC running leak-free with this premium 2-piece rear main crankshaft seal set from LowPricedAutoParts – the trusted retailer of automotive parts and accessories dedicated to outstanding customer service. This high-quality seal (Shaft Dia 2.430", OD 3.045", Width 0.225") is precision-engineered for GM inline-6 engines, covering 194 CID (3.2L), 230 CID (3.8L), 250 CID (4.1L) and 292 CID (4.8L) applications from 1962–1968 in models like Chevy II, Bel Air, Biscayne, C10 Pickup, Impala, Camaro, Chevelle, Suburban; GMC 1500 Series, Suburban, 3000/3500 trucks and similar full-size cars & light-duty pickups. These straight-six engines powered countless family vehicles, work trucks & early muscle cars with reliable torque, straightforward maintenance & legendary durability when cared for properly. Over decades, original rear main seals can harden, crack or wear from age, heat & mileage, allowing oil to seep past the crankshaft flange – leading to drips, contaminated bellhousings, low oil pressure or messy undercarriage conditions that affect drivability & value in restored classics. This premium 2-piece replacement effectively addresses those concerns, featuring polyacrylate construction for superior resistance to engine oils & temperatures, ensuring long-term sealing in vintage applications. The split design simplifies installation around the crankshaft while maintaining precise fit & retention for clean, confident performance. Installation is common during transmission removal, clutch work or engine service: Thoroughly clean the crankshaft flange & block housing, inspect for scoring/grooves (consider polishing or repair sleeve if present), apply approved assembly lube sparingly, position seal halves carefully without distortion, torque retaining bolts evenly in sequence to factory specifications, and monitor for leaks during initial startup & break-in. Professional assistance is recommended for accurate alignment & to resolve any related crankshaft or housing issues. At LowPricedAutoParts, customer service is our top priority. Message us your VIN, exact year/model/engine code or any fitment questions – our knowledgeable team responds quickly to confirm compatibility & offer personalized guidance. Shop with confidence knowing this premium rear main crankshaft seal set is backed by our commitment to quality parts & exceptional support.
