Designed for YZ-2, YZ-2T and YZ-4 platforms, the Yokomo RP-089PUA Purple Ultra Rear Spring offers a hard spring option for carpet and artificial turf racing. It helps reduce unsettling rear movement during aggressive driving and quick direction changes.
The spring is compatible with various YZ-2 and YZ-4 chassis types such as B-YZ4SF, B-YZ2, B-YZ2CA, B-YZ2DT and similar models, and also fits YZ-2T truck series. That makes it a flexible upgrade across the YZ line.
With a tuned spring rate and solid construction, the RP-089PUA improves handling precision and component longevity on carpet and turf surfaces. It is a practical choice for racers seeking firmer rear control without complex setup changes.
