PROGRESSIVE SUSPENSION Shock Springs - 12-Series - Black - 105-150 lb/in 03-1368B

If your suspension feels inconsistent on the track or trail, your shocks are likely fading under sustained load—a common problem that Progressive's 12-Series shocks eliminate entirely. Gas-charged damping and six-stage automatic valving keep your bike planted and responsive through every corner, lap, and condition, while the heavy-duty spring option ensures you're properly sprung for your actual riding weight and passenger habits. Order the correct spring rate now and avoid the performance penalty of under- or over-sprung suspension.
