Baron Heavy‑Duty Rear Shock Spring – 800 lb Rate – Fits Yamaha V‑Star 1100 (1999‑2009) – Red – ba8543vs – Made in USA

OVERVIEW

The Baron Heavy‑Duty Rear Shock Spring is engineered to restore firmness and precise handling characteristics to the Yamaha V‑Star 1100. Constructed with an 800 lb/in linear spring rate and finished in durable red coating, this component replaces worn factory units to improve suspension responsiveness. Designed exclusively for the Yamaha V‑Star 1100 lineage, this upgrade eliminates sag and delivers immediate feedback for street riding applications.

ENGINEERING & PERFORMANCE

Featuring a dedicated 800 lb/in linear spring rate, this upgrade ensures the rear shock mechanism functions closer to optimal calibration even when supporting additional weight or passenger load. The increased tension significantly reduces rear-end bounce and enhances damping control, particularly during cornering maneuvers and travel over uneven pavement. As a single linear rate unit, the spring provides a consistent resistance profile throughout its stroke. The component fits effectively within both stock-height frames and motorcycles utilizing existing lowering kits.

WHY RIDERS CHOOSE THIS

Riders choose this replacement spring to correct suspension bottoms-out, excessive sag, and unpredictable handling caused by age, weight, or poor previous maintenance. The stringent 800 lb/in linear rate offers a reliable reinforcement that stabilizes the chassis without necessitating a full shock cartridge replacement. This design accommodates cruisers modified for a lower stance while still providing high-load support for daily commuting or weekend rides. By returning damping authority to the suspension assembly, it extends the functional life of the rear shock and improves overall crash-free stability.
