These work great on my 1990 Chevy C1500. Everyone knows the stock battery cables on an OBS is a bad design, but with these the cables it's a snug fit without stripping out the threads in the battery. There is also plent of room on the other end for accessories. I mananged to fit 0 gauge lugs on both ends when redoing the positive and negative leads for a Big 3, along with 4 Hi-Low relay terminals, and an amp.
