Description
Challenger 16138 Hydraulic Cylinder – CL9, CL-10, and Inground Lift Replacement
When replacing a hydraulic cylinder on a Challenger 2-post or inground lift, correct identification is critical. All Challenger cylinders are stamped with their part number on the outer tube housing, approximately 6 inches from the bleeder screw at the top of the cylinder. Confirm the stamped number reads 16138 and does NOT include an “R” suffix – this part does not replace the 16138R variant. Before installation, drain the oil reservoir, clean the tank, and flush the hydraulic system of debris and old fluid to maintain the warranty on the replacement cylinder.

Fitment & Ordering Notes
Verify the stamped number 16138 on your cylinder’s outer housing before ordering. The stamp is typically located approximately 6 inches from the bleeder screw at the top of the cylinder. Some CL10 lifts were built with ram-style cylinders and require a different part. Some models listed have newer versions using a different cylinder – always confirm the stamped number matches 16138. This listing covers ONE cylinder and does NOT replace the 16138R cylinder.
