These components are suspension elements designed to enhance the performance of off-road vehicles, specifically those utilizing a progressive or multi-spring rate suspension system. They are typically shorter, lighter springs positioned to engage early in the suspension travel, providing a softer initial ride. A practical application is found in UTVs and ATVs where the initial compliance contributes to improved comfort and traction over small bumps and uneven terrain.
Their strategic placement offers several advantages. They contribute to a smoother ride quality, reducing driver fatigue and improving overall vehicle control. Historically, addressing harsh ride characteristics in off-road vehicles involved complex and costly suspension modifications. These spring elements provide a more accessible and tunable solution, offering increased articulation and minimizing body roll during aggressive maneuvers. The overall effect is enhanced vehicle stability and predictability.
