CASE 580 Backhoe Fitment

Published aftermarket fitment includes the CASE 580 Super K, 580 Super L and 580 Super M backhoe loaders. The cylinder is cross-referenced under multiple CASE part numbers, so the number on the original cylinder or machine parts information is the best starting point for identification.

Verify the Stabilizer Cylinder Before Ordering

Confirm the equipment model and original part number, then compare the bore, stroke, rod diameter and mounting dimensions with the existing cylinder. This is particularly important when working across different generations of the CASE 580 platform.
