B-MAX rear damper spring description

The BM-S12100 is a rear coil spring intended for RC rear damping systems fitted to B-MAX series shocks. It functions as an aftermarket replacement to adjust how the rear end responds to compression and rebound events when installed correctly.

Assembly uses common RC damper steps: remove the cap and spring retainer, swap the spring onto the shaft, reseat the retainer and reinstall the cap. For setup, change spring preload or rate in modest steps and evaluate handling on-course to reach the desired balance.

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.

Are these springs robust enough for regular track sessions?

The springs are built for RC damping use and will tolerate routine track running; inspect periodically for coil deformation or wear and replace if signs of fatigue appear.

Can I swap this spring between different B-MAX rear models?

The listed B-MAX models share compatible rear shock assemblies so the BM-S12100 can be interchanged, but always confirm fit and clearance on each chassis before running.

How should I adjust preload to improve cornering?

Increase preload gradually to reduce body roll and sharpen turn-in; small steps and track testing will reveal the best setting for your setup and driving style.
