Product Details

ACL Bearings 8B684A-30 Standard Connecting Rod Bearings are precision-engineered replacement bearings designed specifically for Oldsmobile V8 engines including 260, 307, 350, and 403 cubic inch applications from 1964 to 1990. These bearings feature the -30 suffix designation, indicating they are 0.030 inch undersize bearings designed for use with reground crankshafts.

Key Features:

  • Tri-metal construction with hardened steel backing for superior strength and durability
  • 0.030 inch undersize design for compatibility with machined crankshafts
  • Precision-manufactured to OEM specifications for proper fit and clearances
  • Enhanced crush design improves bearing retention in connecting rod housing
  • Eliminates flash plating on bearing backs to improve heat transfer
  • Increased eccentricity compensates for bore distortion at high RPM

ACL Race Series bearings bring decades of engineering expertise and metallurgical innovation to engine builders and performance enthusiasts. With a distinguished track record in motorsports applications worldwide, ACL bearings deliver the reliability and precision required for both stock rebuilds and high-performance applications. These connecting rod bearings are an essential component for any Oldsmobile V8 engine rebuild requiring undersize bearings.

Great

Excellent experience. Cheapest price I could possibly find, reasonable shipping cost (other people tried to charge upwards of $20 where I was only charged $14). Shipping was VERY quick. <br><br>I was slightly weary of ordering from Autoplicity as I had never heard of them before but from here on out they will be the first place I check. Could not be happier. <br><br>There is nothing that could have made this experience more enjoyable for me.

You are the best price.
