OEM replacement hydraulic cylinder for EQ Systems SM series tube-in-tube jack legs. 30" stroke. Fits SAE and NPTF fittings. Direct drop-in replacement for the SM series.
The EQ Systems 1135 is the OEM replacement hydraulic cylinder for SM series tube-in-tube jack legs with a 30" stroke. When the internal cylinder seals fail — causing the jack leg to drift, fail to hold position, or lose lifting capability — replacing the cylinder restores the jack to full operating condition without replacing the entire jack assembly.
The fittings on this cylinder are compatible with both SAE and NPTF fitting types, accommodating hose configurations from different model years. Confirm your jack's stroke length before ordering, as SM series cylinders are available in multiple stroke sizes.
SM series replacement cylinders are available in 16", 20", and 30" stroke lengths. Ordering the wrong stroke will result in a cylinder that does not fit or function correctly in your jack leg. To identify the correct cylinder: Measure the stroke length of your existing cylinder, or use the Hydraulic Cylinder Identification Chart for Tube-in-Tube Jacks available through EQ Systems service and support documentation. You can also contact EQ Systems technical support with your jack model number for assistance.
The 1135 cylinder fittings have been used with both SAE (straight thread O-ring) and NPTF (tapered pipe thread) fitting types. This dual compatibility accommodates the range of hydraulic hose configurations found on SM series jacks across different production years, reducing the need for additional adapters in most installations.
