UB1A : The UB1A module is the base module for use with the RubberShox patented UB series of modular bump stops. UB1 is a replacement for the factory Mercedes-Benz Sprinter van bump stop with a 60A firm, heavy duty, bump stop. This should be used with other UB2/UB3 modules. For a universal replacement, see the UB1 module.
The RubberShox UB series is a patented, modular bump stop replacement solution. Combine a compatible base UB1 module with one or more interlocking UB2 submodule(s) and a UB3 end module to customize the height of your bump stop.
