I have several sets left of drop gears for Quick Change rear ends. These gears fit pretty much all quick change brand rearends in the full size and mid size range. They don't fit most mini stock versions but am told they do fit a few styles of these as well. They have the most common standard 10 splines. I have several ratios left as listed below. They range from 1 brand new, never used, several hardly used, to several used but in excellent like new shape. I am asking $85 for the brand new one, $75 for the hardly used ones, and $65 for the used ones. As you probably already know these gears are reversible so you can gear down and up with every gearset. These are all the more expensive version made to take extremely high horsepower and torque.
