Enginetech BC154J25 Main Bearing Set .25mm Undersize for 3.6L Pentastar

The Enginetech BC154J25 is a precision-engineered crankshaft main bearing set designed for Chrysler, Jeep, and Volkswagen 3.6L Pentastar V6 engines. This set features .25mm (.010") undersize bearings, specifically designed for engines with crankshafts that have been machined or require slightly smaller bearing dimensions during rebuilds.

Key Features:

• Made from high-quality alloys engineered for optimal load capacity and anti-friction properties
• Manufactured on state-of-the-art equipment ensuring consistent bearing thickness for proper oil clearances
• Precision-controlled parting line chamfers cut at the correct angle for proper oil flow without reducing oil pressure
• High strength construction with excellent wear resistance, anti-seizure properties, and embeddability
• Materials designed to provide superior protection and durability during engine rebuilds
• Meets or exceeds OE specifications for reliable performance

Enginetech main bearings utilize either copper/tin/lead with steel backing or aluminum alloy construction, depending on the specific application requirements. Each bearing is precision-machined to ensure proper fit and optimal engine performance. Note that thrust washers are sold separately when not molded into the bearing assembly.
