Traxxas 5858P Pink XX-Long Progressive Rate Springs for Ultra Shocks (2)

The Traxxas® 5858P Pink XX-Long Progressive Rate Springs are a pair of custom-wound replacement springs designed for XX-long Ultra Shocks™. Progressive-rate winding means the spring starts soft for small bump compliance and progressively stiffens as travel increases — giving you responsive control over rough terrain while still absorbing hard impacts without bottoming out. The pink color adds a bold, distinctive look to your suspension setup. Sold as a pair.
