Genuine Lippert replacement motor spacer for single, double, and triple electric Coach Step and Stromberg Carlson sliding step assemblies. Keeps the motor properly suspended and gears in the correct position. 1/2" outer diameter × 1/4" inner diameter. Sold individually — most applications require 6 spacers total. 1-year warranty.
The Lippert 128958 is the replacement motor spacer for Lippert electric Coach Step and Stromberg Carlson sliding step assemblies. The spacers sit on the motor mounting bolts, keeping the motor properly suspended in the step housing so the drive gears engage at the correct depth and alignment. When spacers crack, split, or go missing — which happens over time as the plastic fatigues from vibration and temperature cycling — the motor shifts out of position, causing gear skipping, binding, or step failure.
The original spacers are cast metal or plastic depending on the year; the current 128958 replacement is a machined part that is generally more durable than the originals. Sold individually — check your step assembly's service diagram to confirm how many spacers your specific configuration requires before ordering.
Most Lippert Coach Step motor assemblies use 6 spacers total — typically 2 spacers per mounting bolt across 3 bolts. This is referenced as Part 38, Quantity 6 in Lippert's Coach Step assembly documentation. Check your step's parts diagram or service manual to confirm the exact quantity for your single, double, or triple step configuration before ordering. The 128958 is sold as one spacer per package — order the full quantity needed at once.
