Rear spring matched to B-MAX rear shocks

The BM-S12100 is a rear shock spring designed for RC damping on B-MAX series rear shocks. It serves as a direct replacement option to influence compression and rebound characteristics when fitted into compatible rear shock assemblies.

Fitment follows standard RC damper procedure: remove the shock cap and spring retainer, transfer the spring onto the shock shaft, reseat the retainer and refit the cap. When tuning, alter spring rate or preload in small increments and evaluate handling on the track rather than relying solely on numeric settings.

Compatibility

  • B-MAX2MR2
  • B-MAX2MR3
  • B-MAX2RS
  • B-MAX43G
  • B-MAX43GF
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which B-MAX rear models will accept this spring?

The spring is specified for use with B-MAX2MR2, B-MAX2MR3, B-MAX2RS, B-MAX43G and B-MAX43GF rear shock assemblies.

Is it acceptable to fit this spring to front shocks?

This part is intended for rear shock applications; fitting to the front requires verifying the spring free length and rate against the front damper assembly to ensure proper behavior.

What handling effects should I expect after swapping springs?

A stiffer spring typically reduces roll and limits squat under acceleration, while a softer spring increases compliance. Make small preload and rate changes and test on track to dial in balance.
