Yokomo YOKBMS1275 - SS1275 Front Suspension Spring for Tuning Applications  [YOKBMS1275]

Spring Role in Front Suspension

This front shock spring serves as a direct replacement for R/C front shock assemblies and is listed as Yokomo model YOKBMS1275 with the SS1275 marking. It restores suspension travel control and enables riders to tune preload and match springs with different dampers to affect handling traits.

Install notes: slide the spring onto the shock shaft and locate it against the retainer and spring cup per your shock design, check that the piston moves freely and that the spring is concentric on the shaft, and confirm correct preload and travel before operation. No special tools are normally required beyond typical shock assembly tools and a hex driver.

Tuning role: the SS1275 changes front spring rate and preload, which alters front-end grip and balance when used alongside damper valving, ride height adjustments, and sway bar settings. Fit springs in matched pairs to keep a consistent feel across the front axle.
