Selection and Ordering Internal Synchronization Parts for OLS 2-Stage Telescopic Jacks
For twin jack systems we recommend always replacing the internal synchronization parts on both jacks at the same time. We also recommend ordering and replacing the gland seal kits for the appropriate model of OLS 2-stage telescopic jacks. The gland seal kits can be found in the HST Telescopic Jacks spare parts section.
