Serpent 500915 Rear 13mm Shock Spring 2.2lbs Blue  [SER500915]

13mm Rear Coil Spring Overview

This Serpent 500915 rear shock spring is a replacement coil intended for rear shock assemblies that accept a 13mm spring diameter. The item designation lists the main features: 13mm size, rear application, 2.2lbs spring rate and blue finish.

Installation is straightforward: compress the spring as needed and slide it onto the shock shaft over the spring cup or retainer fitted to your shock body. After fitting, verify the spring seats correctly and set ride height, then compare with the original spring to ensure proper placement before the first run.

For setup, a 2.2lbs spring rate increases stiffness versus softer springs and will influence body roll, corner bite and rebound control. Combine this spring with suitable shock oil and adjust preload in small steps to refine handling and get clearer feedback during test runs.
