These RACEOPT Progressive Dynamic Springs provide a practical way to refine your RC car's suspension. With a progressive tension range from T2.5 to T3, they alter stiffness as they compress to support controlled handling across varying track conditions.
The red and black RACEOPT springs are designed to progressively stiffen, offering a softer initial response for small bumps and stronger support during heavy compressions, aiding stability and predictable cornering.
Suited to many common shock designs, these springs fit without complex modification. Installation is simple, making them a practical upgrade for competitive and casual drivers alike.
