Roll Pin Counter Shaft

The Winters Roll Pin Counter Shaft (part number 67991) is a precision steel roll pin engineered for Winters Falcon transmission applications. This component serves as a critical fastening element in high-performance transmission assemblies, securing the counter shaft in position during engine operation. Built from steel for durability and dimensional accuracy, this roll pin meets the OEM specifications required for proper transmission function and longevity.

In transmission rebuild and repair work, roll pin integrity directly affects gear mesh alignment and power transfer efficiency. The counter shaft roll pin must withstand both radial and shear loads without deformation or failure. This Winters-branded fastener is manufactured to maintain consistent tolerances that ensure proper fit within the transmission housing, preventing shaft movement that could cause binding, noise, or catastrophic transmission damage. The compact dimensions (1.95 x 1.35 x 3.75 inches) and minimal weight (0.02 lbs) reflect the precision engineering typical of transmission components.

Technicians rebuilding Winters Falcon transmissions—whether for performance street applications, drag racing, or vintage automotive restoration—depend on OEM-specification fasteners to restore transmission reliability. A single failed roll pin can result in shaft slip, gear grinding, or complete transmission failure under load. This component is sold individually, allowing buyers to purchase exactly what they need for repair kits or full transmission overhauls without excess inventory.

Winters transmissions are recognized in the performance automotive market for build quality and responsiveness. Maintaining that standard requires using genuine replacement fasteners rather than generic alternatives that may not meet the precise tolerances these transmissions demand.
