Show original supplier description
The Tomei TA203A-MT01A is a forged H-beam connecting rod engineered for high-performance applications. Constructed from durable SNCM439 material, this rod offers enhanced strength and reliability for demanding engine builds. The H-beam design provides a balance of rigidity and light weight, crucial for optimal engine response. This specific model features a length of 150mm and is designed to transfer the compression pressure from the piston to the crankshaft efficiently. The specifications indicate a bush inner diameter of 45mm and a bolt size of 3/8-24, with dimensions including a small end diameter of 22x23.0mm and a large end diameter of 48x26.4mm. The height under the neck is 40mm, with a bearing width of 17.0mm. Note that for normal pistons, a recession may be required to achieve proper fitment with the 150mm length. The Tomei TA203A-MT01A connecting rod is explicitly listed for use with the 4G63 engine, including variations like the 4G63-2.2L.
