Serpent 500906 Red 13mm Front Spring 3.4lbs  [SER500906]

Specs and Purpose of the 13mm Front Spring

The Serpent 500906 is a red 13mm front shock spring rated at 3.4lbs, offered for front suspension tuning or replacement where a 13mm coil is required. It delivers a defined spring rate to aid chassis balancing and setup adjustments.

Installation is carried out using standard shock maintenance steps: open the shock, remove the old coil, fit the new 13mm spring onto the shaft, position the spring seat and preload, then close the shock. Make sure the spring sits square on the retainer and that the damper operates smoothly through its range.

When used for tuning, the 3.4lbs specification stiffens front response and reduces dive under load; employ it when a firmer front end is desired or to fine tune handling. Combine changes with consistent damper oil and preload so you can accurately compare results.

This accessory is intended for RC front suspension setup and routine servicing on compatible 13mm shock assemblies.
