Yes, that jack leg will replace your 4100 series jack leg. The 4100 jacks are an Acme screw jack and the 4800 are ball screw. The 4100 should be replaced by the 4820. The part # is 736515, which is the product code 313774. I just confirmed this with Lippert. I am having my websites team update the information on our site. I apologize for the confusion.
