ACL FA20 Standard Size w/ Extra Oil Clearance Rod Bearing Set - 15-18 WRX

The ACL Race Standard Size Rod Bearing Set for the 2015-18 Subaru WRX and 2013-17 BRZ are precision manufactured, featuring enhanced bearing designs and materials. 

Precision Manufacturing:
ACL Race Series performance engine bearings are manufactured to exacting tolerances. Micron tolerance machining supported by precision measurement systems delivers consistent accuracy to key characteristics like wall thickness and crush. This ensures reliable fit and helps maintain consistent clearances. 

Bearing Materials:
ACL doesn't use flash plating to improve bearing retention and maximize heat transfer. ACL blends bearing characteristics to provide high strength and excellent seizure resistance. The multi-alloy bearing features a lead-tin-copper overlay, nickel barrier, copper-lead-tin lining, and SAE1010 high tensile bearing steel support liner.

Bearing Design:
  • Improved bearing retention from higher radial contact pressure. Locks the bearing into the housing.
  • More effective heat dissipation through improved thermal transfer
  • Increased bearing eccentricity to improve shape adaptation and compensate for bore distortion at high speed operation
  • Assist in the formation of hydrodynamic oil film
