Traxxas Rear Progressive -10% Rate Green RC Spring (2) - 6866

The Traxxas TRX6866 rear springs are progressive-rate suspension springs offering a -10% softer rate, finished in green to distinguish them from standard-rate springs. Designed as a direct-fit spare or suspension tuning option for compatible Traxxas models, these RC suspension springs allow you to soften the rear end compared to the stock setup — useful when dialling in handling on smoother surfaces or lighter builds. Sold as a pair, they're a straightforward swap using standard Traxxas shock hardware.

Key Features

• Progressive spring rate softens gradually under compression, providing a more compliant initial stroke before firming up

• 10% rate compared to standard Traxxas rear springs, offering a noticeably softer rear suspension feel
• Direct-fit Traxxas replacement springs — no modification required for compatible models
