Traxxas GTR Rear Progressive (Natural Finish) RC Shock Spring - 8445

The Traxxas TRX8445 rear shock springs are GTR-specification progressive rate springs for Traxxas models, designed as a direct-fit spare or setup option for vehicles running GTR shock absorbers. Sold in pairs with a natural finish, these springs carry a progressive rate of 1.042 and are listed under Traxxas part number 85086-4, making them straightforward to cross-reference when ordering replacements.

Key Features

• Progressive spring rate of 1.042 provides a suspension response that firms up as compression increases, rather than delivering a flat linear feel throughout the stroke.
• Natural finish steel construction — no coating that could mask cracking or fatigue, making wear easy to spot during maintenance checks.
• GTR shock specification ensures these springs seat and compress correctly within Traxxas GTR shock bodies without modification.
• Sold as a pair, so both rear corners are covered in a single purchase.

What's Included

• 2 x Traxxas GTR rear shock springs (natural finish, progressive 1.042 rate)

What You Need

• Traxxas GTR rear shock absorber assemblies (if not already fitted to your vehicle)
