Proform high-torque starters are 100 percent new, not rebuilt. They feature an offset design that results in more clearance between the oil pan and the starter. The powerful units are offered in a variety of styles, finishes, and other options for both manual and automatic transmission applications. These replacements are available for countless vehicles from the 1950s and up.
