FAQ

Q1: Is this a complete set for a full engine rebuild?
A1: This set includes the main crankshaft bearings and connecting rod bearings required for the bottom-end rebuild of a 4HK1 or 6HK1 engine. Please check your specific repair needs, as other components like thrust washers or piston rings are not included.

Q2: Do I need to machine the crankshaft when installing these new bearings?
A2: It is critical to measure the crankshaft journals for wear, out-of-round, and taper before installation. If the crankshaft is within OEM specifications, these bearings can be installed as-is. If the crankshaft is worn, it must be reground to the appropriate undersize, and matching undersize bearings must be sourced separately.

Q3: Are these bearings suitable for high-performance or remanufactured engines?
A3: Yes. These bearings are made from high-quality materials designed for OEM-level performance and durability, making them an excellent choice for standard repairs, remanufactured engines, and applications within the engine’s original performance specifications.
