What We're About

We provide our clients expertly crafted, finished crankshafts which meet specifications and are delivered on time. Southern Illinois Crankshaft is big enough to meet the most demanding challenge yet small enough to give you the personal attention and expeditiuous service only a smaller, more agile team can provide. We produce large quantity or one item jobs, but we do every job with craftsmanship, speed and precision that is second to none. While maintaining our core areas of expertise, we've become specialists in pump cranks used for oil field production.  We've made smart investments in the latest technology and the brightest personnel - it's a big part of how we deliver high-quality finished products on time, on budget and on target.

Where We've Been

In 1985, Southern Illinois Crankshaft, Inc started as a specialist in engine rebuilding and heavy duty crankshaft repair. We provided machining services primarily to contractors, the performance diesel industry and the agriculture industry. Driven by customer need, Southern Illinois Crankshaft designed and then began manufacturing a crankshaft that would withstand the high horsepower generated in the performance diesel sport. With the purchase of an Okuma MacTurn 550 in 2006, Southern Illinois Crankshaft moved into manufacturing crankshafts full-time.

Where We Are Today (areas of expertise)

Additional investments in CNC machining centers have provided us the ability to manufacure both small and large runs of exceptional quality. We continue to have great success providing quality crankshafts for the performance diesel industry and pump crankshafts for the oil industry.
