Refresh your RB7.5 setup with the Kyosho W5313-21 suspension springs to achieve steadier handling and improved corner traction. Crafted to support precise suspension tuning, they are well suited to both practice sessions and race conditions within the Legendary Series.

Key Advantages of the W5313-21 Springs

  • Compatibility: Specifically designed for the Kyosho RB7.5 to guarantee correct fit and intended shock performance.
  • Durability: Engineered from materials that resist wear under frequent track use.
  • Performance: Promotes reduced body roll and steadier mid-corner balance for consistent lap times.
Remark :
Due to limited stock availability, please notice that some Kyosho 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.

Do these springs pair well with stiffer anti-roll bars?

Yes, combining these springs with a firmer anti-roll bar can reduce body roll further, but balance both front and rear changes to keep predictable handling.

Are replacements readily available?

Kyosho parts like the W5313-21 are commonly stocked by hobby retailers; keep spare springs on hand if you run frequently to avoid downtime.

How should I test spring changes at the track?

Make one change at a time, record lap times and driver feel, and adjust damping or preload to dial in the behaviour across different sections of the circuit.

Can I mix these springs with aftermarket shocks?

You can, provided the shocks accommodate 1.2mm wire springs and 61mm length; confirm spring seat fit and travel to prevent binding or bottoming out.
