This GPM aluminium front adjustable spring damper set is machined to provide durable, low friction suspension for the TEAM LOSI ROCK REY. The shock shaft is strengthened from 3.0mm to 4.0mm to improve resistance to bending under load while retaining the original spring wire diameter of 1.4mm. The damper midpoint distance of 122mm keeps the intended suspension geometry for predictable responses during technical driving.
