Racing-grade steering linkage with the 3Racing Sanwa 3.0mm V2

The 3Racing Sanwa Single Arm 3.0mm V2 is engineered to maintain accurate servo-to-linkage geometry during aggressive inputs. The critical 20mm hole-to-ball spacing matches many Sanwa servo layouts, helping preserve steering ratios and predictability in tuned chassis setups.

Technical benefits for tuning

  • Durable Construction: Designed to withstand frequent adjustments and the demands of track use without compromising control precision.
  • Precise Fit: The 20mm hole spacing ensures repeatable geometry for setup consistency and easier corner-to-corner tuning.
  • Enhanced Input Fidelity: Minimises mechanical play to improve driver feedback and allow finer servo endpoint and rate adjustments.

What is the hole-to-hole measurement and why does it matter?

The arm uses a 20mm servo gear hole to ball end spacing, which is important for matching steering geometry and preserving intended steering ratios on tuned cars.

How does this arm affect setup adjustments?

A consistent arm geometry simplifies dialing in end points and dual rates, since linkage lengths and angles remain predictable under load.

Is this arm suitable for fine tuning competitive handling?

Yes, its consistent fit and stiff behaviour make it appropriate for competitors who need repeatable steering response while refining setup parameters.
