PRODUCT DESCRIPTION
Product details
"Heavy Duty" series I-Beam connecting rods for Mitsubishi 4B11 EVO X are designed for high power/supercharged applications. Manufactured from the highest quality 4340-EN24T high-strength steel, they feature a specially optimized shape for high performance and extreme durability. The bushings, made of aluminum-silicon/bronze alloy, feature a radial oil groove. They have been shot peened to relieve material stress and subjected to multi-stage heat treatment to increase their rigidity. Strict manufacturing process tolerances ensure a perfect fit and optimize oil clearances. Flexing and twisting are strictly controlled. Each connecting rod includes 3/8" ARP 2000 head bolts with a strength of 220,000 psi. Optionally, 260,000 psi ARP L19 material can be purchased as an upgrade. The complete kit includes ARP molybdenum lubricant and full assembly instructions.
