POLARIS XPTURBO RACE SERIES PERFORMANCE ROD BEARINGS.
New ACL rod bearings for the Polaris XPTurbo engine (XPT, Turbo-S, ProXP, Turbo R) are available exclusively through BC. 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. A blend of characteristics to provide high strength and excellent seizure resistance with no flash plating applied to further improve bearing retention and maximise heat transfer. Improved bearing retention from higher radial contact pressure with more effective heat dissipation through improved thermal transfer. Bearing Eccentricity Definition: Gradual reduction in wall thickness between the crown and parting line. ACL Race Series performance engine bearings feature increased eccentricity to improve shape adaptation to compensate for bore distortion at high speed operation. Assists in the formation of hydrodynamic oil film.
  • Superior seizure resistance
  • Superior cavitation resistance
  • Superior wear resistance
  • Superior protection against oil starvation
