1974 CUMMINS SMALL CAM Connecting Rod For Sale (Part 121579)
About This Cummins SMALL CAM Connecting Rod
This is a good, used connecting rod for the 1974 Cummins SMALL CAM, carrying part number 121579. The connecting rod links a piston to the crankshaft and transfers combustion force into crankshaft rotation. A bent, cracked, worn, or damaged rod can cause knocking, uneven operation, bearing failure, or severe internal engine damage. Rod length, journal size, piston-pin fit, cap arrangement, and balance are matched to the engine, so another rod with a similar appearance may not be interchangeable. Compare the original rod, page photos, and any listed casting or part number before ordering. The part is inspected and tested before it ships, identified by its stock number (DT051), and backed by included warranty coverage. Freight ships nationwide, quoted to your delivery ZIP. Use the page photos and listed details to compare it carefully with the component being replaced before purchase. Have your engine's year, make, model, and application ready and call (800) 696-5459 to confirm fitment before ordering.
