The Yokomo YS-1480 HSS Long Shock Spring is an aftermarket replacement designed to sit inside typical shock assemblies and alter the effective spring rate and feel. The orange finish marks this HSS line and the item is targeted at tuners rather than original equipment repair.
As a purely mechanical component, the spring changes how the shock compresses and rebounds by fitting over the shock shaft within the body. It is an efficient way to adjust mid-stroke support and overall stiffness without immediately changing pistons or damper fluid.
Basic installation is simple for anyone comfortable with threaded shock parts: disassemble, remove the stock spring, place the YS-1480 and reassemble. Afterward, set preload and check ride height before undertaking longer test runs.
Tuning pointers: expect modest shifts in cornering balance and mid-stroke support when swapping spring rates or lengths. Use spring changes alongside oil and collar adjustments for a more controlled setup.
