The LA CHOPPERS Heavy Duty Shock Spring is a rear‑mount shock spring engineered for street‑oriented motorcycles built between 2000 and 2017, including the FXST and FLST models. Delivered as a matching pair, each spring features a distinctive red finish that not only adds visual flair but also signals the component’s heavy‑duty construction. Designed specifically for the suspension and frame system, the spring provides the stiffness and durability required for aggressive street riding while maintaining the precise response expected from a performance‑focused shock.
This product is cataloged under the “Big Shock Springs” series and is identified in the OEM lineup as SPRINGS SHOCK RED 89‑07. Although the series also offers blue and gray options, the Heavy Duty Shock Spring supplied here is the red variant, ensuring compatibility with the original equipment specifications for the designated model years. The pair‑pack format simplifies installation and guarantees balanced performance on both sides of the rear suspension.
