Selection and Ordering Internal Synchonization 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 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.
