Review: Great for OBS side mount terminals - 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. Review: Good quality bolt, not some cheap coated wannabe. - Good quality, surprised me actually. Many of the other battery terminal bolts you see here on desertcart twice the price are garbage, cheap and shear apart when you apply any pressure as you tighten them. Didnt shear off or strip out my new battery, served its purpose perfectly, looks good and holds its torque. Simple, great value and effective.
