Description
Designed to withstand higher RPM conditions, ACL Race Series Connecting Rod Bearings are available for many of the popular 4, 6 & 8 cylinder applications and feature:
* *High strength overlay plate* with reduced thickness for improved fatigue properties
* *Hardened steel backs* on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
* *Increased crush* for improved bearing retention
* *Elimination of flash plating* on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
* *Increased eccentricity* to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
* *Tight consistent wall tolerances* to help you maintain consistent clearances.
* *Enlarged ID chamfers* on bearing edges where required to accommodate large fillet radius on performance crankshafts.
Multiple sizes available, please select desired size:
“H” = Standard Size
“H-.25″ = .25mm Thicker than stock. Use this when your crank is cut .010”
“H-.50″ = .50mm Thicker than stock. Use this when your crank is cut .020”
“H-.025″ = .025mm Thicker than stock. Use this when you need .001” less oil clearance.
“HX” = .025mm Thinner than stock. Use this when you need .001″ more oil clearance.
