Lippert Gen 1 Level Up 14K Hydraulic Jack Seal Kit for 2021 Alliance Paradyme

We have not verified a seal kit for the exact jack described. The numbers in the question must be distinguished from a seal-kit part number. Lippert identifies 8005413 as a complete 14K Level Up follow-leg assembly and lists 25712510 among the numbers it supersedes. That is evidence of a replacement assembly, not a seal kit, and does not support the earlier statement that both numbers are obsolete or unavailable.

Lippert describes 8005413 as a second-generation follow leg with 20-inch travel and a 9-inch footpad. Before selecting a replacement for the reported front-passenger position, verify the installed jack's complete label, revision, lead/follow function, mounting pattern, hydraulic connections and stroke against Lippert's replacement requirements. Coach year, an approximately 27-inch length, a ten-hole description or the shape of the top does not establish the exact jack or seal dimensions.

We have not established an approved internal seal set, rebuild procedure or interchangeable aftermarket kit for this specific assembly. Do not select seals from a nominal bore or tube diameter alone. Have Lippert or a qualified hydraulic/RV technician confirm serviceability and the required assembly or seal specification from the actual jack identification. This answer does not confirm ERVP stock or authorize a substitute repair kit.
