Features That Matter on the Track

  • Compatibility: Intended for SOR-020 and SOR-020D chassis platforms.
  • Precision Design: Twin 1.8mm holes for consistent damping characteristics.
  • Durability: Manufactured to stand up to repeated testing.
  • Easy Installation: Supplied in pairs for quick replacement and comparison runs.
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.

Should I change spring rates when fitting these pistons?

You may need to tweak spring rates slightly to match the altered damping profile; small changes often restore desired balance without major overhaul.

How many pistons are included and what size are they?

The package includes two 13mm pistons designed to work with compatible shock assemblies so you can change both shocks or test one side at a time.

Is there a recommended service interval for these pistons?

Check piston and shock condition during regular maintenance or after heavy runs; clean oil and inspect for wear to keep consistent damping.
