Yokomo 13mm big bore rear shocks for SO/MO chassis

Specifically tuned for the rear of SO/MO models, the Yokomo S4-S1L13 X30 13mm Shock Set combines big bore oil capacity with a stout 3.0mm shaft to deliver steady damping and improved resilience. The design helps keep the rear end predictable when you are pushing lap times or refining handling balance.

Notable Features of the S4-S1L13 Shock Set

  • Big Bore Design: Thirteen millimetres of bore allows greater oil volume for smoother travel and reduced fade.
  • Durable Construction: A 3.0mm shaft improves resistance to bending and enhances longevity under heavy use.
  • Perfect Fit: Tailored to fit the rear of SO/MO chassis, including SOR-020 and SOR-020D models.
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.
Yes, these replace standard rear shocks on compatible SO/MO cars and are intended as an upgrade for improved damping control.
Begin with your usual spring rate and a mid-range oil to compare performance, then move to heavier or lighter oil based on rebound speed and track grip.
Regularly check for leaks, keep shafts clean, and replace oil and seals as part of routine maintenance to preserve damping performance.
