UB1 : The UB1 module is the base module for use with the RubberShox patented UB series of modular bump stops. UB1 is a universal replacement for the factory bump stop with a 60A firm, heavy duty, universal bump stop and should be used with other UB2/UB3 modules. For Mercedes-Benz Sprinter van bumpstops, see the UB1A module.
The RubberShox UB series is a patented, modular bump stop replacement solution. Combine the base UB1 module with one or more interlocking UB2 submodule(s) and a UB3 end module to customize the height of your bump stop.
UB1 is the base module of a patented, modular, universal rubber bump stop system. Required for use with other RubberShox Modular Bump Stops.
Dimensions: 1.4” height x 4” width. Combine with UB2 and/or UB3 modules to increase height. UB2 - 1.85”, UB3: 2.91”.
Heavy Duty: Each unit supports 2500 lbs, or 5000 lbs per axle. Hardness: 60A.
Disclaimer: These do not increase vehicle load capacity. Refer to your vehicle’s factory GVWR and payload rating before operation. Always follow applicable laws/regulations during operation and exercise discretion.
