This is the genuine Lippert replacement V2 controller assembly for compatible 3-point hydraulic leveling systems installed on Class C motorhomes. If your existing controller has failed, shows erratic behavior, or is damaged from moisture exposure, this water-resistant unit restores factory-level operation and connects directly to your existing harness.
The Lippert 2021123312 V2 controller assembly is a genuine OEM replacement component designed specifically for 3-point hydraulic leveling systems used in Class C motorhome applications. The "V2" designation indicates the second-generation controller design, which improves on the original with enhanced water resistance and revised internal logic for more consistent auto-leveling performance.
Class C motorhomes using Lippert's 3-point hydraulic leveling layout typically deploy one front jack and two rear jacks, with the controller managing pump motor activation, jack extension sequencing, and retract/auto-level commands. This assembly is the brain of that system -- replacing it with a genuine Lippert part ensures correct signal timing and compatibility with the existing hydraulic pump and solenoid wiring.
Sealed housing resists moisture intrusion common in exterior or under-chassis controller mounting locations.
Second-generation controller with revised auto-level sequencing for more reliable jack deployment and retract cycles.
Matches the OEM connector and wiring harness of compatible Lippert 3-point Class C leveling systems -- no splicing required on supported builds.
Sourced directly from Lippert (part 2021123312, vendor ref 17-0949) for assured fit and function on compatible systems.
This controller is designed for 3-point hydraulic leveling systems installed on Class C motorhomes by Lippert. Before ordering, confirm:
If you are unsure of your system generation, note the part number printed on your existing controller housing or contact Lippert customer support with your coach VIN for confirmation.
After installing a new controller, check the hydraulic fluid level in the leveling pump reservoir. Low fluid can cause erratic jack behavior that mimics controller faults. Use Lippert-approved hydraulic fluid for the leveling system -- do not substitute with generic ATF unless confirmed compatible by Lippert for your specific pump model.
