Serpent 500907 Shock 13mm spring fr pink 3.6lbs  [SER500907]

Shock spring details

This Serpent 500907 spring is an RC-scale shock spring specified as 13mm with a 3.6lbs rate and pink finish, intended for use in R/C general suspension setups. It is designed to function as a replacement or spare for compatible shock assemblies that accept 13mm coil springs.

Installation notes: fit the spring onto the shock shaft and seat it on the spring retainer as your shock design requires, verify free travel and spring alignment before final assembly, and check preload to achieve the target ride height and balance.

Tuning role: the 3.6lbs rate increases spring stiffness compared with lower-rate options, affecting body roll, pitch control and response over jumps; use incremental changes and drive testing to find the preferred balance between grip and responsiveness.
