Mid-USA Replacement Spring Kit for Springer Front End
The Mid-USA Replacement Spring Kit is a comprehensive suspension refresh solution designed for aftermarket “Old School” style springer front ends. This kit addresses common issues such as front-end sag, poor dampening, and spring fatigue by providing a complete set of precision-wound inner and outer springs. By replacing the entire stack, you ensure balanced compression and rebound across the front assembly.
