ACL Bearings 4B8430H-STD Race Series Rod Bearing Set Suzuki GSX-R1000

The ACL Race Series 4B8430H-STD is a high-performance connecting rod bearing set designed specifically for Suzuki GSX-R1000 motorcycles with 988cc and 999cc inline-4 engines. These trimetal bearings are manufactured with innovations, processes and materials resulting from several years of testing and research.

Key Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing
• Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing
• Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films
• Manufactured from 3 layers of hardened steel, copper and nickel to withstand high RPM, temperatures and load

Technical specifications: Maximum overall length: 15mm (0.5906 in), shaft size range: 34.976-35.000mm (1.377-1.378 in), tunnel size range: 38.000-38.016mm (1.4961-1.4967 in), maximum wall thickness at crown: 1.488mm (0.0586 in).
