8B663A-010 ACL Aluglide Rod Bearings - SB Chevy 350 & LS - .010 Oversize

The new generation engine bearings � smart, strong, tough. Aluminum Tin materials have been around since the 1960s. They have traditionally been the choice of Japanese and European manufacturers for low load, gas, passenger cars. As the loads developed by high horsepower late model engines increased, so too did the need for a stronger bearing material. The need for lead free engine components has increased, without sacrificing the load carrying capacity required for modern engines. One of the reasons why Aluglide� has been such a positive achievement is due to ACL Bearing Company�s in-house research & development, further refining the alloy for a winning advantage over the competition. It features a strip cast microstructure which is the result of the inclusion of alloying elements and careful heat treatment. This gives superior bonding surfaces, particularly between the aluminum bond layer and the steel which are then optimized and remain that way to handle long term maximum loads. Put simply, the new bearings can take a higher load in the way the stress is transmitted to the steel. Additionally, the harder surface of the tough alloy gives substantially reduced wear and minimizes any possible shaft abrasion, resulting in an extended service life.
