The Yokomo RP-081 Racing Performer Ultra is a 3.2 linear shock spring designed for 1/10 on-road touring cars. Its equal-pitch coil fosters predictable damper movement and stable response across the travel. The component is finished in black and the hardness is laser-engraved on the end to simplify spring selection during setup changes.
Product notes indicate the spring has been used with BD8 configurations, confirming fitment with those chassis types. This item is supplied as an RC spare part for touring-car shock assemblies only.
Fitting is standard for coil damper springs: place the spring onto the shock shaft between the spring retainer and top mount, set preload to suit ride height, and verify free travel. Use the RP-081 as a reference linear option when consistent mid-stroke support is required without top-end ramping.
