Yokomo YS-1560L Pro Long Shock Spring - Orange, RC Tuning Accessory  [YOKYS1560L]

Extended shock spring for setup changes

The Yokomo YS-1560L is supplied as a longer orange-coded pro shock spring intended for RC-scale suspension tuning and setup adjustments. It works as a drop-in option when additional travel or shifted preload range is required inside a damper assembly, and it is presented as an accessory part for models rather than a vehicle component.

Practical role: a longer spring shifts the preload window and changes the effective static ride height, interacting with damper oil and piston selection to influence transient reactions and corner support. Expect ride-height changes and the need to retune damping after installation to keep handling predictable.

Installation notes: confirm internal shock length and spring seat dimensions before installing, take the shock off the model, decompress and swap springs while checking proper seating on the retainer and shaft, then reassemble. Perform a few controlled runs to verify smooth travel and to dial in preload and damping.

Tuning tips: make incremental adjustments to chassis balance and roll stiffness, pair spring changes with damping and anti-roll bar settings, and track the effects using measured ride-height and lap-time feedback rather than visual guesses.
