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

Compatibility Notes for Rear Shocks

The Serpent 500915 rear shock spring is provided as an RC replacement coil for rear shock assemblies that accept a 13mm spring diameter. Its description highlights the key attributes: 13mm diameter, rear application, a 2.2lbs spring rate and a blue finish.

Fitting is simple: compress the coil and place it over the shock shaft onto the spring cup or retainer supplied with your shock. After installation, ensure the spring seats evenly and verify the ride height, comparing to the original spring to confirm correct fit and orientation before extended running.

In setup work, a 2.2lbs rate will firm up the rear end compared with softer springs, affecting roll, cornering grip and rebound characteristics. Use incremental preload changes and pair the spring with appropriate shock oil to fine tune handling without overcompensating for a single change.
