Motorcycle Shock Springs

Frequently Asked Questions

• How do I choose between straight-rate and progressive shock springs?

  Straight-rate springs deliver consistent stiffness for stable handling on smoother surfaces, while progressive-rate springs start softer and stiffen with increasing travel for varied terrain and impacts; pick the type that matches your riding style and check the manufacturer’s rate curve and intended use.
• Which physical dimensions and specs should I match to my suspension?

  Match free length, travel capacity (to avoid coil bind), wire diameter, coil spacing and overall diameter to your fork or shock design and hardware so the spring allows full stroke plus preload without interference.
• How should rider weight, gear and luggage affect spring selection and setup?

  Select a spring rate and preload range that account for total load so sag and travel remain correct under riding conditions; remember too much preload can make small bumps harsh, while too little leads to frequent bottoming.
• What spring traits suit different ride types like dirtbikes, adventure bikes, ATVs, and street bikes?

  Dirtbikes benefit from progressive, long-travel springs for impact absorption; adventure bikes favor adjustable-preload/progressive springs for mixed loads; ATVs need heavy-duty, anti-bow designs for rough terrain; street bikes typically use straight or mild progressive springs tuned for comfort and stability.
• What durability, maintenance, and installation factors should I consider for aftermarket shock springs?

  Choose springs with quality wire, proper coil spacing and fatigue treatments (like shot peening) and corrosion-resistant finishes, inspect regularly for coil set or corrosion, and install with correct alignment, clearance and spring seats; if you add heavier luggage or larger tires, plan on re-evaluating spring rate and valving.
