Key benefits

• Precision clearances for dependable oil film control and crankshaft protection at high rpm.
• Complete 8-cylinder big-end bearing shell set for the S65 V8.
• Two clearance options to suit your build: H-STD for standard oil clearance and HX-STD for increased oil clearance.
• Ideal during bottom-end refresh, engine rebuilds, track preparation and preventative servicing.

Finish and colour variation

ACL Race Series shells often appear darker in colour. The electroplated overlay can look black, brown or blue and may tarnish slightly. This has negligible thickness and does not affect fitment or function. ACL omits the bright tin flash commonly seen on aftermarket bearings to ensure consistent shell-to-rod housing contact under heavy load and temperature.
