Winters 1550 Gundrilled Lower Shaft for Open Drive Quick Change

The Winters 1550 is a precision-engineered gundrilled lower shaft designed for open drive quick change rear end assemblies. This critical drivetrain component features gun drilling technology that reduces rotational weight while maintaining structural integrity for high-performance racing applications.

Key Features:

• Gundrilled construction for optimal strength-to-weight ratio
• Designed specifically for open drive quick change configurations
• Precision-machined to Winters' exacting specifications
• Compatible with Winters quick change rear end systems
• Reduces unsprung weight for improved handling and acceleration

This lower shaft is an essential replacement or upgrade component for racers running Winters quick change rear ends in circle track, sprint car, and other dirt track racing applications. The gundrilled design removes material from the center of the shaft, decreasing rotational mass without sacrificing the torsional strength needed to handle high-horsepower racing conditions.
