LippertPart 128958 / 47-0020Electric Step RepairLippert 128958 Motor Spacer for Electric Coach Steps

Keep your electric entry steps operating smoothly with this genuine Lippert replacement motor spacer. Engineered to fit single, double, and triple electric Lippert coach steps as well as Stromberg Carlson sliding step assemblies, this small but critical component restores proper motor alignment and function without requiring a full step mechanism replacement.

Restore Reliable Step Operation with the Right Replacement Spacer

When an electric coach step motor loses its spacer, the entire step mechanism can bind, operate erratically, or fail to extend and retract correctly. The Lippert 128958 motor spacer is the correct OEM-specified replacement to get your step assembly back in proper working order. It installs in the motor mounting area of the step drive mechanism and maintains correct shaft clearance and alignment.

This spacer is sold individually, making it an economical solution when only the spacer itself is damaged or missing rather than the full motor or step assembly.

Broad Step Compatibility

Fits Lippert single, double, and triple electric coach steps as well as Stromberg Carlson sliding step models that share the same motor mount design.

Precision Dimensions

Machined to 1/2" outer diameter and 1/4" inner diameter for accurate fitment on the step motor shaft without play or binding.

Sold Individually

One spacer per order -- order the exact quantity you need without paying for parts you don't.

90-Day Warranty

Backed by Lippert's limited 90-day manufacturer warranty for defects in materials and workmanship.

Direct Replacement: The Lippert 128958 (also referenced as SKU 47-0020) is the manufacturer-specified spacer for electric Lippert coach step motors. Using the correct OEM part avoids fitment issues that aftermarket alternatives can introduce in step drive mechanisms.
Fitment Note: This spacer is compatible with the electric motor-driven step assemblies sold under both the Lippert and Stromberg Carlson brands. If you are unsure whether your steps use this motor mount configuration, locate the motor housing on your step assembly and verify the shaft diameter matches the 1/4" inner bore of this spacer before ordering.
Quantity Note: This listing is for ONE motor spacer. If your step assembly requires multiple spacers -- for example, on a triple-step unit -- order accordingly.
Maintenance Tip: When replacing the motor spacer, inspect the motor mounting screws, wiring harness connector, and adjacent plastic housing for wear or cracking. Addressing worn components at the same time prevents a repeat service call on a step that gets cycled hundreds of times per season.
