About GP Suspension

At GP Suspension, we engineer suspension systems that transform your ride by blending race-proven technology with everyday performance. Rooted in decades of roadracing experience, our Ventura, California-based team crafts fully adjustable, American-made suspension components tailored to your unique riding style and needs.

Race-Bred Innovation for the Road

Our journey began on the racetrack, where we developed advanced suspension solutions for AMA and club-level competitors. This hands-on experience in high-stakes environments has been instrumental in designing products like our 25mm Cartridge Kit for Harley-Davidson baggers. This kit features a three-valve system—including a base valve for enhanced fluid control—that offers a smoother, more controlled ride, maintaining better traction and stability across various conditions .

Precision Engineering, Personalized for You

Every suspension kit we produce is custom-built to match your weight, riding style, and bike specifications. We understand that setup is key to good suspension, and we take pride in delivering a kit that is tailored for you.
