ACL Race Series Tri-Metal Main Bearings for NISSAN 200SX S14 / Silvia S15 (SR20DET)

ACL Race Series Tri-Metal Main Bearings for NISSAN 200SX S14 / Silvia S15 (SR20DET)

ACL Race Series tri-metal bearings are manufactured to exacting tolerances. CNC machining is carried out to within microns, before metrology checks on the diameters, the thickness and the width of the ACL Race Series tri-metal bearing. ACL Race Series bearings therefore give a reliable and consistent fit in your performance engine. ACL Race Series tri-metal bearings are in fact made up of 4 layers:

- SAE1010 steel on the outside
- 0.3mm copper alloy
- 0.0001mm nickel
- 0.013 to 0.018mm copper alloy

This choice of materials, combined with the manufacturing processes, makes ACL Race Series tri-metal bearings more resistant to increases in power, torque and engine speed. The compressive strength of ACL Race Series tri-metal bearings brings reliability to your engine, even on turbocharged or supercharged builds running high boost, or on highly tuned engines running high crankshaft speeds.
