ACL tri-metal bearing shells have been developed to meet the demands of heavily used engines, whether they are tuned or intended for competition use. They withstand high engine speeds, heavy loads and temperatures higher than those encountered in road use.
Thanks to their multi-layer design, they offer excellent resistance to fatigue, wear and high pressures, thereby helping to maintain engine reliability under the most demanding conditions.
Composition:
- High-strength steel backing
- Copper intermediate layer for excellent load-bearing capacity
- Nickel diffusion barrier
- Copper/white metal alloy surface layer ensuring excellent running-in behaviour and good compatibility with the crankshaft
The set is for all 4 connecting rods with a standard-pitch crankshaft.
