B-MAX rear shock spring overview

The BM-S12100 is a rear shock spring intended for use with B-MAX series rear dampers on RC cars. It offers a replacement spring to influence rear compression and rebound response when fitted to the compatible shock units listed below.

To install, follow standard damper maintenance: remove the shock cap and spring retainer, fit the spring onto the shaft, seat the retainer and refit the cap. When tuning, pair rate and preload adjustments with oil and damping changes, and test progressively to refine handling.

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.

What tuning benefits does the BM-S12100 deliver?

Changing to this spring can alter roll resistance and rear squat characteristics; combine spring changes with damping and preload adjustments to achieve the intended handling response.

How should I care for rear shock springs?

Keep springs free of debris and check for worn or compressed coils; replace if any deformation or loss of tension is observed to maintain consistent performance.

Does the spring influence rebound or compression more?

The spring affects both compression and rebound dynamics, but the final balance depends on damper oil, piston selection and damping settings; adjust these elements together for best results.
