Details:

ACL Bearings are a top choice for engine builders especially for high-horsepower builds.

Features:

• Rod bearings

• .001" Oversized

• Made using softer metals 

• Designed to allow a thin layer of oil lubricates the connection between the bearings and the rod  allowing the crank to "float" to reduce wear
   

NOTE:

1. These bearings are for the 7 bolt main motors and are .0005" thinner per half to give .001" extra clearance for the standard sized cranks
