This is the Traxxas 5859 Rear Springs White

Traxxas progressive-rate springs are custom-wound to provide responsive control for small bumps, with a progressively stiffer rate to absorb harder impacts. Spring rates are identical to stock Slash springs and are ideal for all nitro and electric Rustler and Stampede applications, as well as Bandit and Nitro Sport. Two spring lengths are offered for front and rear applications.

Compatibility:

• Traxxas Drag Slash
• Traxxas Nitro Slash
• Traxxas Slash 2wd
