This rear shock spring is designed for rear damper use on compatible Yokomo B-MAX43 chassis. Identified by BM-S12110 and listed under SSS 12110, it is supplied as a single replacement spring for rear shock assemblies.
Replace the spring during damper maintenance or when changing baseline spring rates; the BM-S12110 works with the existing damper internals and alters how spring force contributes in the assembly, changing rear support and rebound behavior.
Fitting involves a standard rear spring swap: remove the shock, decompress and remove the old spring, install the BM-S12110, then reassemble and check ride height and damper travel. Fine adjustments to preload and damping will help dial in handling for different track surfaces.
