Traxxas XX-Long Progressive Springs Rear +20% Blue (2)

Traxxas XX-Long Progressive Springs add a progressive-rate setup to the rear suspension so small impacts are handled smoothly while the springs stiffen up for hard landings. These springs suit builders and tuners who want clearer handling feedback and improved bottoming resistance on long shock builds.

Key Features

• Custom-wound XX-long design for improved wheel control over small bumps.
• Progressive-rate profile that becomes stiffer under heavier compression to absorb hard landings.
• Offered at a +20% rate with a blue stripe for easy identification during setup changes.
• Rate selection helps tune suspension balance for lighter or heavier vehicle configurations.
• Rates are expressed relative to stock springs, letting you fine-tune handling without guesswork.
• Designed to fit long Ultra Shocks and Big Bore shocks that use 3768 spring retainers.
• Not compatible with GTR shocks.

Why Choose These Springs

These rear springs are a straightforward upgrade when you need firmer mid-to-bottom travel control without losing compliance over small terrain. They work well for trail driving, bashing, or any build where long shocks are used and you want a clearer, more predictable feel from the suspension.
