Overview and fitment notes

This Serpent 500907 component is a 13mm diameter, 3.6lbs-rate coil spring finished in pink, intended for general R/C suspension applications. Use it as a spare or upgrade in setups that take 13mm springs.

Installation notes: slide the spring onto the shock shaft and locate it against the spring retainer per your shock's design, ensure the spring is aligned and not rubbing any ports, and set preload carefully to dial in the correct ride height.

Tuning role: moving to a 3.6lbs rate increases stiffness, which helps control pitch and roll; pair changes with shock oil and rebound adjustments and validate performance through controlled test runs.

Will these fit shocks built for 13mm springs?

Yes, these springs are manufactured to the 13mm coil diameter standard and are compatible with shock assemblies designed to accept 13mm springs, provided retainers match.

Do I need different shock oil with a 3.6lbs spring?

Not always, but a firmer spring often pairs well with slightly heavier oil to maintain damping balance; adjust oil and piston choice as part of a tuning session.

How should I set initial preload with these springs?

Start with a moderate preload, drive to observe squat and roll, then add or remove a few turns to reach the intended ride height and handling response.
