The J-Extensions expand the MOS UpLift™’s mounting surface from 26ʺ (66 cm) to 38ʺ (96.5 cm), allowing you to install wider roof boxes and ski/snowboard racks. More importantly, they unlock configurations that aren’t possible without this upgrade: carrying a canoe, paddleboards, adding a third bike rack, or even a second kayak on a single MOS UpLift™. 

Each kit covers one MOS UpLift™ and includes two pieces, one for each arm
