Serpent 500906 front shock spring 13mm red 3.4lbs  [SER500906]

Front 13mm Shock Spring

This Serpent 500906 is an RC-scale front shock spring specified at 13mm with a 3.4lbs spring rate and red finish. It is supplied as a replacement or tuning option for front shock assemblies where a 13mm spring fits, offering a defined spring rate for chassis setup work.

Installation is straightforward for familiar shock service routines: disassemble the shock, remove the old spring, fit the 13mm spring onto the shock shaft and reassemble with correct spring seat and preload. Check that the spring seats flush on the retainer and that the shock compresses freely through its travel after reassembly.

As a tuning component, the 3.4lbs rating affects front-end stiffness and response; use it when you need firmer front support or to alter balance during setup. Combine with consistent damper oil and preload adjustments to evaluate handling changes methodically.

Designed strictly as an RC accessory, this spring is intended for controlled setup and maintenance of front suspension on compatible 13mm shock assemblies.
