If your Kwikee electric entry steps are moving slowly, grinding, or not deploying at all, the gearbox and motor assembly is the most common failure point. Lippert part 676062 is the direct-replacement unit -- same 5:1 gear ratio, same 14 Nm torque output, same 17 mm double-flat output shaft, and the same curved Link Assembly A geometry the original system was built around. Bolt it in and get your steps working again.
Kwikee electric steps have been factory-installed on thousands of Class A, Class C, fifth wheels, and travel trailers for decades. When the drive assembly fails -- whether from water intrusion, worn gears, or a seized motor -- the entire step set becomes inoperable. This Lippert assembly replaces the gearbox and motor as a single unit, restoring full extend/retract function without rewiring or modifying the step frame.
The assembly ships with the curved Link Assembly A pre-attached, which mates to the driver-side step arm pivot point on standard single-step and double-step Kwikee configurations. The 110 mm x 210 mm bolt pattern on the mounting plate is a direct match to the original bracket footprint, so no drilling is required on most applications.
Trades motor speed for torque, delivering enough mechanical force to move step treads under load without oversizing the motor.
Matches OEM spec for standard Kwikee single and double step sets. Adequate for typical entry step loads up to rated capacity.
Direct engagement with the Kwikee step arm drive socket. No adapters or machining needed when replacing a like-for-like gearbox.
Operates on standard RV 12-volt house power. Low output RPM translates to smooth, controlled step travel on extend and retract cycles.
The Kwikee step mechanism uses two link arms -- Link A and Link B -- to translate gearbox rotation into the scissors-style extend and retract motion of the step tread. Link Assembly A is the curved, driver-side arm that mounts directly to the gearbox output shaft. It is the piece that takes the most stress during deployment and is frequently the source of flex, cracking, or binding on high-cycle assemblies.
This part includes Link Assembly A pre-installed on the gearbox, so you receive the complete drive-side subassembly in one box. If only the link arm is damaged and the gearbox itself tests good, Lippert sells the link arm separately -- but for most worn or failed assemblies, replacing the complete unit is the more reliable repair.
Gearbox body, 14 Nm 12V motor, and curved Link Assembly A are all included as one pre-assembled unit. No separate motor sourcing or link-arm fabrication required.
This is a straightforward bolt-on replacement for any RV technician or experienced DIYer. The general procedure:
The motor direction is determined by polarity at the controller output. If steps extend when they should retract after installation, swap the two motor leads at the connector. Do not run the motor stalled against the end of travel for extended periods -- the step controller's built-in timer or current-limit circuit is the normal protection against this.
Kwikee step systems use either Link Assembly A (curved, driver-side) or Link Assembly B (straight or mirrored, passenger-side) depending on step width and mounting orientation. Part 676062 includes Link Assembly A only. Inspect your existing hardware or reference your step model number before ordering to confirm you need the A-side assembly.
If the gearbox is functional but other parts of the step system are worn, Lippert also offers replacement step controllers, step arms, wiring harnesses, and complete step assemblies under the Kwikee and Lippert product families.
