About Us

POSIES is a proud family-owned business that has been shaping the street rod world since 1964. Founded by Ken "POSIES" Fenical, better known simply as POSIES, the company quickly earned a reputation for pushing the envelope with creativity, craftsmanship, and forward-thinking design. Ken’s innovative spirit laid the foundation for what has become a trusted name in hot rodding for over six decades.

What started as a quest to improve ride quality and stance led to the creation of our iconic SuperSlide Springs—a solution born from real-world experience and a drive to do things better. That same spirit still fuels everything we do. Today, POSIES SuperSlide Springs, Packaged Suspension Kits, and a wide array of hot rod parts continue to lead the industry in performance, reliability, and American-made quality.

All of our springs are crafted in Central Pennsylvania using high-grade American steel, ensuring unmatched strength and durability. While imitations may exist, they can’t match the ride quality or proven legacy of POSIES products. We also offer the largest selection of leaf springs for Street Rods, Customs, and Trucks in the market.

Every part we design is engineered to work together as a system, taking the guesswork out of building. POSIES is proud to work with fellow pioneers in the industry, including Pete & Jakes, Super Bell, IDIDIT, Vintage Air, Borgeson, and Lokar—names we trust and use ourselves.

Whether you need a full turn-key build or just a few custom touches—like louvers or a top chop—our full-service shop is here to help bring your vision to life.

At POSIES, you’re not just buying parts—you’re investing in a legacy of innovation, integrity, and family craftsmanship that spans generations.
