Cosworth Heavy Duty Forged connecting Rod 4G63
Manufacturer Part # 20002668
If you’re planning on building the 4G63 to handle substantial amounts of horsepower and boost, then you should build the block with a set of our Heavy Duty Connecting Rods. With over 50 years of racing heritage, we know what it takes to deliver an engine component that can sustain the perils of high performance driving. Like all of our connecting rods, these have been fabricated from 4340 steel, and have gone through the careful process of proprietary forging to maintain optimum weight and promote better strength.
Additionally, the heavy duty connecting rods for the 4G63 feature a radial truss for reduced reciprocating mass. These connecting rods will be ready to drop in your block with a set of H11 steel rod bolts and once installed, they will be able to handle the added horsepower and boost numbers created from larger turbochargers, to custom tunes. Build your 4G63 block with the best available rods brought to you by your experts here at Cosworth.
