Serpent 500910 Shock Spring 13mm Front Green 4lbs  [SER500910]

13mm front shock spring, 4lbs

This Serpent 500910 is an R/C-scale shock spring designed for front shock use, identified by its 13mm active length and a 4lbs spring rate in a green finish. It is intended as a direct spring option where short 13mm springs are required to change front-end feel or to tune weight transfer on small-scale models.

Installation is straightforward for hobbyists familiar with common shock assemblies: remove the shock cap and shaft, slide the spring over the shock shaft onto the spring retainer, then reassemble ensuring preload and travel clearance are correct. Confirm inner-diameter and retainer compatibility before fitting to avoid binding.

In tuning, a 4lbs front spring typically increases initial resistance compared with softer springs, affecting ride height and roll stiffness; use it when seeking firmer front support or to rebalance a setup after changes to other suspension components. Combine with appropriate damping and ride-height adjustments rather than changing springs alone for best results.
