Orange Long Pro Shock Spring Yokomo YS-1560L for RC Suspension Tuning  [YOKYS1560L]

Orange long shock spring — tuning use

The Yokomo YS-1560L is a long, orange-coded pro shock spring offered as an RC suspension accessory to help with model setup and handling tweaks. It serves as a replacement spring when greater travel or a different preload range is needed in a shock unit, and it is supplied as a single part for scale models rather than as a vehicle assembly.

Practical role: extended springs alter preload and static ride height and work in concert with damper oil grades and pistons to affect transient response and cornering support. Installing a longer spring normally alters static ride height and requires damping updates to keep the car stable over bumps and through turns.

Installation notes: verify your shock's internal travel and the spring seat dimensions first, remove the shock, decompress and swap springs while ensuring the spring seats correctly on both the retainer and shaft, then reassemble. Afterwards, do a few slow runs to check for binding and to set preload and damping.

Tuning tips: change chassis roll stiffness and balance incrementally, combine spring swaps with damping and anti-roll adjustments, and note ride-height and steering changes with measured checks rather than guessing.
