HappiJac 4220/4820 Camper Jack Parts Diagram, Brackets & Controls
Need a replacement HappiJac camper jack, support bracket or controller? This 4220 / 4820 identification guide separates the jack body, drive motor, crank, mounting reinforcement and swing-out components. Use the printed OEM number and the existing system's hardware details to identify the correct part before ordering.
Understand the bracket profiles before ordering
182491 is a 5-inch mounting bracket, 182492 is the 16-inch L reinforcement, 182493 is the 16-inch Z mounting bracket, and 182494 is the 16-inch flat mounting bracket. These are different profiles. These bracket profiles are alternatives for different mounting arrangements, not components that all install together. Check camper mount, jack model, orientation, hole pattern and loading instructions.
HappiJac replacement jacks, brackets and controls
Maker callout G
759927 — Vertical CCS motor head, white
This is the vertical current-sensing drive head, not a universal motor for every HappiJac controller.
Maker callout H
736514 — 4220 Acme screw jack, white
Complete single 4220 jack; verify rating, lift and mounting arrangement from the jack label.
Maker callout I
736515 — 4820 heavy-duty Acme jack, white
Different model from the 4220. Match the exact 4820 jack specification rather than relying on cabinet colour.
Maker callout J
182496 — Swing-out extension bracket pair, white
A pair of extension brackets for the intended HappiJac mounting arrangement. Check truck clearance and the correct jack brackets.
Maker callout L
182436 — Standard 4-inch crank handle
Manual crank for the applicable HappiJac drive hub; differs from the longer 8-inch 1824362 option.
Maker callout P
182491 — 5-inch mounting bracket
Manufacturer lists a distinct 5-inch mounting bracket; inspect hole spacing and existing bracket before replacement.
Maker callout Q
182492 — 16-inch L-reinforcement bracket
L-profile mounting reinforcement. Not equivalent to the 182493 Z-profile or 182494 flat bracket.
Maker callout R
182493 — 16-inch Z-mounting bracket
This listing is for a previously owned Z-profile bracket. Check its photos, condition and mounting holes before ordering.
Prefer a new bracket? Lippert lists 182493 as a single 16-inch Z-bracket for HappiJac 41, 42, 45 and 48 series camper jacks. View new 182493 bracket.
Maker callout S
182494 — 16-inch flat mounting bracket
Flat mounting bracket for the specified jack installation. The 182492 L-reinforcement bracket has a different profile and is not interchangeable.
Maker callout B
723915 — Wireless remote controller, 25A/CCS
Specifically for the 25A/CCS system. Do not confuse with older 183070 remotes for controller 139315.
Electric-drive and remote-control compatibility
The white 759927 vertical CCS motor head and 723915 wireless controller belong to specified current-sensing equipment. Lippert also identifies an older 183070 remote only for obsolete controller 139315, with a different controller/remote upgrade kit (733540). Do not choose a remote by colour alone. If replacing any electric control assembly, confirm the original control board, jack model and wiring generation.
Safe jack replacement and factory drawings
Camper jacks carry substantial loads. Support the camper independently before removing a jack or mount. Confirm the mounting system and installation requirements in the manufacturer's documents; follow Lippert's installation and lifting instructions; the illustration is for identifying parts. For the manufacturer’s exploded drawings, see Lippert / HappiJac camper jack components (CCD-0004333, PDF).
For complete jacks and related hardware, browse truck camper jacks or camper mounting and tie-down equipment. Compare the listed part number and mounting arrangement with your existing setup.
