What is the difference between standard and undersize bearings?

Standard size bearings are meant to be installed on a crankshaft that is still within its original factory specifications. Undersize bearings are used when the crankshaft journals have been machined down to remove damage or wear.

Do these bearings come with installation instructions?

While these bearings are designed as a direct replacement, it is always recommended to consult your vehicle's factory service manual or a professional mechanic for the correct installation procedures and torque specifications.

What is the 'HD' designation on these bearings?

The 'HD' in the part number stands for Heavy Duty. This indicates that these bearings are constructed with enhanced materials and design features to withstand higher loads and stresses compared to standard bearings.
