The Gen4 Jimny has an additional cross member added to the chassis below the prop shaft to give the chassis better rigidity. When lifting the Jimny by 50mm and adding castor correction bushes, the prop shaft moves closer to the cross member and this means that when you go over road humps at speed the two knock together briefly.
There are a few cross member drop kits available on the market and we usually let the customer decide if they want to modify their existing cross member themselves, buy one off the shelf or have Des-Sol supply their modified “Cross Bar”, note this is not a “Drop Bar”.
Many off the shelf Drop Bar kits lower your ground clearance after installation which defeats the object of having a lift. The Des Sol Cross Member units are designed with a narrower profile as well as a notch in them to clear the prop shaft so that no ground clearance is lost.
