Key Features:

  • Race Series construction for extreme durability under high loads
  • -.025mm undersize for precision crankshaft grinding and fitment
  • Engineered specifically for Ford 2.3L EcoBoost engines (no notch)
  • High-performance bearing material with superior wear resistance

  • Precision manufactured to tight tolerances for optimal oil clearance

ACL Race Series bearings utilize advanced metallurgy and coatings to withstand the extreme temperatures and loads encountered in racing and high-performance engine builds. The -.025mm undersize allows for proper clearance when using a reground crankshaft or achieving optimal bearing clearances in performance applications.

Quick easy checkout!!

They had exactly what I was looking for at the best price so I went ahead and made the order which I don't regret. They shipped out my order the very next day and received it in about 3 days. Can't comment on the durability yet because I still haven't installed my new Megan Racing muffler. I'll give an update. But I do recommend this site.

Delivered on exact day expected

FAST shipping. Will buy from again. A+A+A+A+A+A+ THANKS

Quick shipping, tire arrived on time. Was the only online tire retailer that had this specific brand and size in stock.

Good prices and reasonable shipping.
