Stromberg Carlson offers two different bundles for setting up a parked trailer: JBP-TTKIT for travel trailers and JBP-FWKIT for fifth wheels. The model numbers are similar, but the contents are not. Use the exact manufacturer part list below to see which pads, support blocks, leveling wedges and wheel chocks come with each kit.
Travel trailer kit — JBP-TTKIT
| Factory part number | Quantity supplied | Component and function |
|---|---|---|
| JBP-813.1 | 1 | Base Pad Peak; tall support block for compatible tongue/scissor/stabilizer-jack use |
| JBP-69.625 | 1 retail pack of 4 | Loose molded EPDM pads, each 6 × 9 × ⅝ inches |

| JBP-C300 | 2 complete sets | Each set comprises one curved wheel leveler, one locking chock and one rubber anti-slip mat |
| Storage bag | 1 | Holds the kit components between trips |
The travel-trailer kit includes four individual pads. The table shows the components supplied within each leveler set so you can compare the kit contents.
Fifth-wheel kit — JBP-FWKIT
| Factory part number | Quantity supplied | Component and function |
|---|---|---|

View JBP-69.625 productCheck your equipment before selecting a bundle
- Identify whether the RV uses scissor/stabilizer jacks, landing gear or hydraulic leveling feet, and confirm the shapes of their contact pads.
- Decide whether your campsite setup calls for under-wheel leveling wedges or primarily jack support blocks.
- Check the maker's individual component load and stacking limits. A kit does not increase the RV's original ratings.
- Use wheel chocks, leveling blocks and stabilizers only in the appropriate sequence; secure the trailer before unhitching and remove portable pieces before departure.
