Product Details

The ACL Bearings 4B1691-040 is a precision-engineered connecting rod bearing set designed for 0.040 inch undersize crankshaft journals.

Key Features:

  • 0.040 inch undersize fitment for reground crankshafts
  • Tri-metal construction with high-strength overlay for superior durability
  • Hardened steel backing provides enhanced support and retention in the housing
  • Reduced overlay thickness improves fatigue resistance under high-load conditions
  • Precision-engineered oil grooves ensure optimal lubrication distribution

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.

Good user interface, works with online shopping resources and has great credibility. I just hope the product is as good as the store.

Product was cheapest I could find and shipping was super fast. Not sure how you could go wrong with them.
