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