Serpent 500905 Front Coil Spring 13mm (3.3lbs, Orange)  [SER500905]

The Serpent 500905 is supplied as a 13mm front coil spring in orange, rated at 3.3lbs. It is designed to increase front stiffness as part of suspension tuning, giving a straightforward method to influence handling and balance.

Fits are generic to front shock assemblies accepting a 13mm coil profile; always check spring perch dimensions and clearance with the shock cap and shaft before installation. This product is a replacement/upgrading spring and not a complete shock unit.

Installation involves removing the shock, opening the cap or retainer, swapping the spring, then reassembling while verifying preload and free length. After fitment, confirm the shaft travels smoothly and that the spring seats properly under full compression and rebound.

Tuning impact: a 3.3lbs front spring offers a firmer feel relative to softer springs and will affect braking dive, roll behavior, and turn-in. Match the spring change with damping and ride-height tweaks to preserve predictable handling.
