Yokomo YS-1560L Pro Shock Spring (Long, Orange) for Scale RC Setup  [YOKYS1560L]

High-travel shock spring for precision setup

The Yokomo YS-1560L is a long, orange-coded pro shock spring produced as an accessory for RC-scale suspension tuning and setup. It fits as a replacement when extended travel or a shifted preload range is required within a damper unit, and is supplied as an individual part rather than a full vehicle component.

Practical role: fitting a longer shock spring changes preload and the static ride height, and works together with damper oil and piston selection to define transient response and corner support. Expect measurable changes to ride height and a need to retune damping to retain predictable handling on varied surfaces.

Installation notes: measure the shock's internal travel and spring seat dimensions before purchase, remove the shock from the chassis, decompress and swap springs while confirming correct seating on the retainer and shaft, then reassemble. After fitting, carry out low-speed checks to ensure free movement and to set preload and damping.

Tuning tips: alter chassis balance and roll stiffness gradually, pair spring swaps with damping and anti-roll bar changes, and document ride-height and steering outcomes with measured data rather than visual estimates.
