3Racing 3RAC-BP128/BU Race Rear-End Stiffener Blue  [3RAC-BP128/BU]

Race-Focused Rear Stiffening with 3Racing 3RAC-BP128/BU

For a more controlled rear end, the 3Racing ball end rear-end stiffener provides targeted reinforcement to the rear link area. It is aimed at racers who tune suspension geometry and need a predictable rear response across different track surfaces.

Ball End Interface for Stable Link Geometry

The ball end connection preserves consistent pivot alignment and reduces variable compliance in the rear links. That stability supports repeatable handling and can make setup adjustments more effective when dialing in rear roll and traction.

Fitment and On-Track Tuning Notes

The stiffener fits a range of rear link designs and is installed with standard hardware. From a tuning perspective, expect a firmer rear platform that may allow you to adjust other parameters, such as shock rate or toe, to recover desired balance.
