Product Details

ACL Bearings 4B1870A-.25 Standard Connecting Rod Bearings feature Duraglide bearing material for superior performance and durability. These precision-engineered connecting rod bearings are manufactured to OEM specifications with a -.25mm undersize to accommodate machined crankshafts.

Key Features:

  • Duraglide bearing material for enhanced wear resistance and load capacity
  • -.25mm undersize for use with ground crankshafts
  • Precision manufacturing ensures proper oil clearances and engine longevity
  • Direct replacement for worn or damaged connecting rod bearings
  • Engineered for high-performance and racing applications

ACL's Duraglide bearing technology provides a tri-metal construction with a steel backing, copper-lead intermediate layer, and a proprietary overlay that reduces friction and prevents metal-to-metal contact during critical engine start-up and high-load conditions. Ideal for engine rebuilds requiring undersized bearings due to crankshaft machining or wear.

Very easy

easy and effective. No problems. enjoyed the service.

smooth

quick ....I hope the product is what I am looking for

I love you

Love the Amazon pay option. Best price I could find on the net was through autoplicity. Great service thus far.

I ordered a Jet Powr-Flo, SKU: JET-69190, from Autoplicity and it was at least 40% off the regular JET price. The site was off on all the vehicles the component fits, but I knew what part to get and I'm completely satisfied. My 2008 Mustang is running smoother than ever and wasting less fuel. So for any performance parts I'll search the maker sites first but I'll purchase from Autoplicity first.

good

Simple and easy, more companies should work this way.

Very easy to order with PayPal!
