Mitsubishi 4G63 and 4B11T engines are among the most popular Sport Compact applications and K1 Technologies has these potent 2.0L powerplants covered with a selection of premium quality H-beam style connecting rods. Among the most popular are 150mm and 162mm long rods for the 4G63 and 143.7mm rods for the 4B11T.
Forged from 4340 alloy steel and precision machined to remove unnecessary weight, they are fitted with premium ARP2000 (220,000 psi) rod bolts. Other important attributes include shot-peening for improved fatigue life, premium bronze wrist pin bushings and balancing to +/- one gram per end.
Finish machined in K1’s Mentor, OH facility, the bores are held to a tolerance of +/- .0001” with 50 millionths on the big end to assure optimum bearing life. Enhanced small end oiling minimizes pin wear.
K1 Technologies has connecting rods for other Mitsubishi applications (6 and 7-bolt), as well as premium billet steel crankshafts (88, 94 and 100mm strokes) for the 4G63.
