Show original supplier description
Constructed from a tri-metal material comprising copper and lead, these bearings incorporate a nickel barrier and SecureBond adhesion technology for enhanced durability and performance. This advanced construction provides a 20 percent higher load capacity, making them suitable for demanding applications. These bearings are available in a +.025mm oversized dimension, indicated by the .026 suffix in some part numbers (e.g., MB5745XPG.026). This particular bearing set is compatible with Subaru FA20 and FB20 engine configurations. Additionally, it fits Toyota 4U-GSE engines, commonly found in vehicles like the Subaru BRZ and Toyota 86/GT86. Compatibility spans various model years, with specific fitment often requiring selection of the correct size and year range at the point of purchase.
