Description
Challenger 11019 Holmac Cylinder Seal Kit for 2-Post Lift Hydraulic Ram Rebuild
This seal kit is designed for older Challenger 2-post lifts equipped with Holmac-brand stick-style hydraulic cylinders. When the cylinder develops leaks at the rod seal or starts bypassing fluid internally, a seal kit rebuild restores proper function. Verify cylinder brand before ordering – these lifts were produced with two different cylinder brands and the seal kits are not interchangeable.
