Traxxas Long Progressive Springs +20% Blue (2)

Traxxas Long Progressive Springs are long, custom-wound progressive-rate springs that improve small-bump control and get progressively stiffer to absorb hard landings. These springs carry a +20% rate and are identified by the blue stripe for quick recognition at the bench.

Key Features

• Custom-wound long springs provide more responsive control over small bumps for smoother tracking.
• Progressive-rate design increases stiffness on heavier impacts to help absorb hard landings without harshness on light bumps.
• +20% rate compared to stock springs lets you add preload and support for heavier setups or extra accessories.
• Blue stripe marks the +20% rate so you can identify rates quickly when tuning or swapping springs.
• Use these springs to tune suspension balance for lighter or heavier vehicle configurations.
• Designed to fit long Ultra Shocks™ or Big Bore shocks that use 3768 spring retainers.
• Not compatible with GTR shocks — use only on the specified shock types.
• Sold as a pair: (2) long progressive springs for front or rear installation as needed.
