Lippert Level Up 14K vs 8K Hydraulic Jack Diagram & Replacement Guide

Compare the original Lippert Level Up 14,000-lb hydraulic jacks with current Gen II replacement families and distinguish them from the separate 8,000-lb mid/rear jack designs. Compare manufacturer jack photographs, mounting-hole patterns and part numbers to identify a replacement. Lead and follow positions, mounting dimensions and hydraulic fittings must match the installed system.

Identification before purchase: Lippert sells different lead and follow Gen II hydraulic jack assemblies. The manufacturer identifies 8005353 as a lead leg and 8005413 as a follow leg, but both current product pages list several of the same earlier MPNs. A supersession list by itself is not enough to choose the correct jack location, hoses or mounting.

Lippert factory photographs: distinguish 13-hole and 8-hole 8K jacks

The images below come from Lippert's own annotated manufacturer product illustrations. These photos show two comparison MPNs, 43345810 and 372892—not the silver 3728923 pictured in the NewRVParts product gallery above. Lippert identifies 3728923 as a silver Gen II 8K jack with an eight-hole mounting pattern. Count the holes and confirm the jack's label, stroke, port locations and original mounting hardware before choosing a replacement.

Lippert 43345810 — older silver 8K, 13 holes. Original Lippert annotated product image; comparison reference only. This is not the 3728923 listing.

Lippert 372892 — black Gen II 8K, 8 holes. Original Lippert annotated product image. The silver 3728923 also has eight mounting holes per its separate manufacturer specification; colour and MPN differ.

Use Lippert's QR-109 and related jack identification guides to compare mounting-hole patterns and the differences between earlier and Gen II hydraulic jacks. The drawings do not establish that the two generations are interchangeable.

Hydraulic jack part-number comparison

Compare the six manufacturer numbers below before selecting a replacement. Pay particular attention to stroke, overall height, mounting position and any differences between the current jack and the original equipment.

Lippert MPN Jack family Product Dimensions and fitment notes
8005353 14K • Gen II 14,000-lb lead-leg hydraulic assembly Lippert identifies a Gen II lead-leg replacement; 20-in stroke and 9-in footpad; its supersession list contains multiple older 14K part numbers.
25712610 14K • legacy Older 14,000-lb clear-anodized hydraulic jack Lippert lists this code among superseded part numbers on newer 14K product pages. Confirm the original plumbing and jack version.
433467 14K • legacy Legacy left-side Level Up hydraulic jack Store describes left-side; newer factory 14K pages include the MPN in supersession lists without proving a universal left/right replacement.
433469 14K • legacy Legacy right-side Level Up hydraulic jack Store describes right-side; confirm the exact original fittings and generation before ordering a successor.
19586010 8K • original 8,000-lb hydraulic jack, early store-listed design Store identifies an original 8K configuration; not a 14K replacement. Verify original mounting-hole pattern.
3728923 8K • Gen II 8,000-lb Gen II silver hydraulic jack Lippert specifies 15-in stroke, 9-in footpad, and 21-1/16-in overall height; 21-1/16 in refers to overall height, not the 15-in stroke; verify both measurements.
Check jack dimensions and package contents: Lippert specifies the 3728923 8K Gen II jack with a 15-in stroke and an approximately 21-1/16-in overall height. The 21-1/16-in overall height is not the same as the 15-in extension stroke. Measure the installed jack and confirm the mounting pattern, hose connections and supplied components before ordering. Check the contents of part 25712610 separately.

What to check on the installed jack

14K legacy vs Gen IIConfirm the original stamped number, mounting-hole pattern, jack stroke, foot diameter, hose port style and whether the replacement is a lead or follow leg. Do not identify the replacement by colour alone.
8K vs 14KThese families are not capacity substitutes. Lippert's 8K Gen II 3728923 factory product describes a 15-in stroke and 9-in footpad; the 14K 8005353 Gen II product describes a 20-in stroke and 9-in footpad.
Hydraulic connectionsDo not infer that elbows, T-fittings or O-ring face seals from one replacement kit are included with another. Confirm the precise kit contents and the factory hydraulic line requirements.
Position and revisionOlder jacks and post-2023 Gen II replacements may use different height or bracket geometry. Follow the Lippert jack comparison and current replacement technical instructions before any chassis work.

These links open manufacturer technical documentation, not competing shopping pages. The 8005353/8005413 product specifications were cross-checked against Lippert's official product documentation; the original factory sheets govern installation, replacement parts and safety. Hydraulic jacks must never be serviced with pressurized lines or an unsupported coach.
