Lippert Solid Step 4.0 Parts Diagram, Models and Fit Chart
Lippert Solid Step 4.0 is a ground-supported manual RV entry system with folding steps, ratcheting adjustable legs and a doorway stow position. Use the factory identification diagram and model chart to choose between the six complete 26-inch and 30-inch assemblies.
Solid Step 4.0 steps have a 500 lb rated capacity. The two-step versions fold manually without lift assist; the listed triple and quad assemblies include integrated lift-assist hardware. Measure both the ground-to-threshold height and the entry-frame opening before choosing a part number.
Solid Step 4.0 part numbers, heights and door widths
Lippert defines doorway width as the distance measured from flange to flange, rather than the advertised nominal door size. The factory door label sizes appear in the chart below.
| Lippert MPN | Steps | Nominal size | Entry height | Flange-to-flange width | Lift assist |
|---|---|---|---|---|---|
| 2024056996 | Double | 26-inch | 22–28 in | 23.75–27.5 in | No |
| 2024056997 | Double | 30-inch | 22–28 in | 27.75–34.5 in | No |
| 2024056998 | Triple | 26-inch | 27.5–39.5 in | 23.75–27.5 in | Yes |
| 2024056999 | Triple | 30-inch | 27.5–39.5 in | 27.75–34.5 in | Yes |
| 2024057000 | Quad | 26-inch | 35.5–46.5 in | 23.75–27.5 in | Yes |
| 2024057001 | Quad | 30-inch | 35.5–46.5 in | 27.75–34.5 in | Yes |
The 26-inch versions serve factory-labelled 26- to 28-inch doors. The 30-inch versions serve labelled 30- to 34-inch doors, provided the actual flange-to-flange width also falls within the range above.
Solid Step 4.0 factory component identification
The Lippert assembly image identifies the top tread, full tread, transport lock, plunger bolt and latching hardware. Use these component names when examining an existing step, rather than assuming similar-looking parts from SolidStep 3.0 will interchange.
Lift-assist versus standard double-step assemblies
In the Solid Step 4.0 range, the triple and quad versions use lift-assist hardware to reduce the effort required to lift or lower the steps. The double versions do not use the same assembly. Keep these differences in mind when identifying latches, legs and mounting hardware.

Check the doorway before replacing RV steps
Measure the flange-to-flange opening, the step height and the available swing clearance. Doors, entry trim, skirting and wheel-well covers can affect the installation even when the nominal doorway size seems correct.
Installation check: Use the current Lippert Solid Step 4.0 installation manual for the exact assembly. Follow its mounting instructions and confirm that the door closes and the transport lock engages before travel.
