Serpent 500911 13mm Front Shock Spring Yellow 4.1lbs  [SER500911]

Precision front spring for setup

This Serpent 500911 component is a front shock coil spring sized at 13mm with a 4.1lbs rate and a yellow finish, aimed at fine-tuning front suspension behaviour on scale RC vehicles.

As a direct spring element it affects ride frequency and initial compliance of the front suspension assembly. Apply it when adjusting roll resistance, improving turn-in or setting ride height through spring preload on compatible shock bodies.

Installation notes and setup tips:

• Confirm the spring seats evenly on the lower retainer and clear the shock shaft fully to avoid any binding.
• Alter preload in small steps and perform controlled runs to assess changes to front grip and steering response.
• Combine spring swaps with shock oil and piston adjustments to fine tune handling rather than expecting springs alone to solve major balance issues.
