Show original supplier description
The ACL G16E-GTS Race Series Main Bearing Set is engineered for demanding engine applications, offering enhanced durability and performance. These bearings are constructed from high-performance Trimetal material, a robust choice for high-stress environments. The design incorporates a high-strength overlay plate with a reduced thickness, which contributes to improved fatigue properties, ensuring longevity under strenuous use. This particular set is specified as STDHX, indicating an extra oil clearance of -0.025mm, which can be beneficial for high-RPM operation by helping to maintain oil film strength. The material designation F780 further highlights its suitability for high-performance racing and motorsport applications. These main bearings are specifically designed for the 2023-2026 Toyota GR Corolla and GR Yaris models equipped with the G16E-GTS engine. Their specifications include a standard shaft size range of 55.988 mm to 56 mm and a minimum standard tunnel size of 60 mm, ensuring precise fitment within the engine block.
