More info
Traxxas Long Progressive Springs are a pair of long, progressive-rate springs tuned to smooth out small bumps while firming up progressively on hard landings. These custom-wound springs help you tune suspension feel without changing shock length or internal parts, making them a straightforward upgrade for shaft-heavy tracks or rough terrain.
Key Features
- Custom-wound long springs for consistent coil spacing and predictable compression behavior.
- Progressive-rate design gives responsive control over small bumps and becomes stiffer on heavy impacts.
- Helps absorb hard landings while keeping low-speed compliance for traction and steering feel.
- Available in multiple rates so you can tune suspension stiffness to match driving style or terrain.
- Fits long Ultra Shocks and Big Bore shocks that use the 3768 spring retainers.
- Not compatible with GTR shocks.
What's Included
- Long Progressive Springs (2)
Why Choose These Springs
These Traxxas Long Progressive Springs are a simple, effective way to tune shock performance without major shock surgery. They work well for drivers who want improved small-bump compliance but firmer support on big hits—useful for off-road bashing, trail runs, and coarse-track setups.
