Sprindex Adjustable Trail / Enduro Coil Shock Spring - 490-560 lbs (65mm Stroke)

Sprindex allows for tool-free, easy adjustment of your coil's spring rate. Adjusting your shock's spring rate can profoundly improve your bike's handling and suspension performance. Depending on trail conditions, you can increase your spring rate for long, efficient climbs and decrease it for plush, controlled descents—or fine-tune your setup for different trails entirely.

No expense was spared on materials or manufacturing. The coil itself is made of super high tensile spring steel—similar to lightweight racing springs to reduce mass and withstand the extreme stresses of higher adjustment settings. The adjustment assembly is built from glass-reinforced polymer, and the included adapters are molded from slippery, low-friction Delrin.

Why Sprindex?

• Tool-Free Adjustability: Twist the dial to change the number of active coils, altering your spring rate on the fly. The currently selected rate is displayed clearly through a window in the dial.


• Progressive Support: Engineered with a linear feel from 0-80% stroke for unmatched small-bump sensitivity and traction, transitioning to a progressive rate for the final 20% of stroke to provide big-hit bottom-out support.


• Weight & Performance: Lighter than ordinary fixed-rate coils, giving you the plush, stiction-free performance of a coil shock with the tuning flexibility you need.


• Low-Friction Adapters: Includes 5 Delrin performance adapters that improve shock fitment, eliminate binding, allow the spring to twist naturally during deflection, and prevent the preload ring from self-adjusting due to coil windup. *(Note: RockShox shocks do not require an adapter, though the performance washer is recommended).*
