Precision Engineered Isuzu 4HK1/6HK1 Connecting Rod
High-grade forged steel construction ensures extreme durability under heavy loads, with micro-polished surfaces for reduced friction and optimized oil retention. CNC-machined to ±0.005mm tolerance for perfect alignment in Komatsu/Hitachi excavators.
Direct OEM Replacement with Performance Upgrade
Heat-treated alloy composition exceeds OEM specs, preventing elongation under high torque. Interchangeable with Hitachi ZX200, Sumitomo SH200, and Komatsu PC300 models—no compatibility risks.
Industrial-Grade Fatigue Resistance
Shot-peened reinforcement at critical stress points extends service life by 40% vs. standard rods. Ideal for mining, construction, and 24/7 quarry operations where engine workload exceeds 8,000 hours annually.
Global Logistics Advantage
Warehouse-stocked in US/EU/Asia hubs for same-day dispatch. Bulk order discounts available for fleet operators purchasing 10+ units—no middleman markups.
