The Serpent 500906 is a front shock spring with a 13mm diameter and a 3.4lbs rate finished in red, offered as a replacement or tuning coil for front shock assemblies suited to 13mm springs. It supplies a defined spring rate useful when adjusting chassis balance.
Installation uses common shock service steps: open the damper, remove the old coil, place the 13mm spring onto the shaft, set the spring seat and preload, and reassemble. Confirm the spring sits flush on the retainer and that the shock cycles without binding.
As a tuning part, the 3.4lbs rating gives firmer front support and alters response; fit it to reduce front compliance or to shift handling feel forward. Use consistent damper oil and preload during testing to isolate the spring's effect.
Intended solely as an RC accessory, this spring is for precise setup and maintenance of front suspension on compatible 13mm shock assemblies.
