Yokomo YOKBMS1275 - Front Shock Spring SS1275 for front suspension tuning  [YOKBMS1275]

Front shock spring overview

This is a front shock spring intended as a direct replacement or spare for R/C car front shock assemblies, identified by Yokomo model YOKBMS1275 and labeled SS1275. It serves the basic role of restoring and controlling suspension movement, allowing hobbyists to adjust preload and pairing with different dampers to tune handling characteristics.

Install notes: slide the spring over the shock shaft and seat it against the retainer and spring cup as per your shock design, confirm free movement of the piston and that the spring is concentric on the shaft, and check for correct preload and travel before running. No special tools are required beyond standard shock assembly tools and a hex driver for associated hardware.

Tuning role: the SS1275 spring influences front-end feel by changing effective spring rate and preload; use it to balance understeer/oversteer tendencies when combined with damper valving, ride height, and sway bar choices. Replace springs in matched sets to keep symmetrical response across the front axle.
