Front spring RP-103BRA overview for YZ-2T/4

The Yokomo RP-103BRA front spring is made for RC race use, with a 1mm increase in free length compared to the standard RP line to change preload and the initial portion of suspension travel.

This hard-type brown spring is tuned to provide a firmer initial rate that sharpens turn-in and gives steadier feedback on carpeted courses for buggy and truck categories. Fit it when you want to limit dive and preserve steering precision through the middle of a corner.

Installation mirrors standard coil-over procedures: replace the front springs with the RP-103BRA, set an initial preload matching your baseline, and adjust shock oil or mounting points as required to re-establish ride height and balance. Make measured tweaks and test on your usual carpet layout to see how the extra millimeter affects vehicle dynamics.

Remark :

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.

Does RP-103BRA fit all listed YZ variants without modification?

The RP-103BRA is intended for the platforms shown; however, ensure the additional 1mm free length clears your shock collars and that the spring seats properly on your shock retainer before finalising fitment.

Are any shock body or cap changes needed for some models?

Most stock shock bodies accept the RP-103BRA directly. If you run nonstandard caps or extended shafts, verify free length and preload window to avoid binding or excessive compression at full travel.

How does the extra millimetre change ride height and what should I measure?

The 1mm increase affects preload and may raise ride height slightly; measure sprung ride height and static droop after installation and adjust collars or mounting positions to maintain your preferred chassis attitude.
