Product Details

The ACL Bearings 4B1146-1.50 is a precision-engineered connecting rod bearing set designed for high-performance and racing applications. This 1.50mm oversize bearing set is manufactured using ACL's advanced trimetal construction, featuring lead, tin, copper, and nickel for superior strength and seizure resistance.

Performance Features:

  • High-strength overlay plate with reduced thickness for improved fatigue properties
  • Hardened steel backing on all rod bearings to improve bearing lining support and retention
  • Elimination of flash plating on bearing backs to improve heat transfer and maximize grip
  • Increased eccentricity to compensate for bore distortion at high RPM
  • Tight, consistent wall tolerances to maintain precise oil clearances
  • Enlarged ID chamfers to accommodate performance crankshafts with large fillet radii

ACL Race Series bearings are proven in professional motorsports competition, from sport compact drift racing to NASCAR, IHRA, and NHRA events. The unique combination of precision metallurgy, engineering design, and quality control delivers the endurance and capability required for engines operating under extreme high-RPM conditions.

Easy order process, quick shipping and great prices. Will shop here again for my truck parts and accessories.

Awesome prices always deliver on time !!

Your competitive pricing won my business through the internet and I wasn't disappointed. The price was great ( about 1/2 MSRP) and item was shipped very quickly. No backorder problems here! I was impressed with the quality of my H pipe and with the packaging.

Autoplicity has the best prices online. Fast ordering process and tracking numbers are sent out the next business day. I highly recommend autoplicity!

So far so good we will see how 2nd day air shipping works. Thanks

i ordered both lockers and air compressor from autoplicity they have the best price online and great customer service! can't wait to order again

this was my first time shopping at Autoplicity and it kind of made me nervous not really knowing anything about their site but i recieved an order confirmation immediatley after ordering and it was shipped extremely fast.
