The RACEOPT Linear Dynamic Spring T3.1 in white is a compact upgrade for enthusiasts aiming to improve rear shock performance. The set contains four springs built with a 1.4mm line thickness to help deliver steadier rear damping.
When matched with progressive springs at the front, these linear rear springs help reduce traction fade during extended running. The T3.1 rate supports consistent handling so the car stays controllable across different track sections.
RACEOPT T3.1 springs fit into many rear shock setups and are quick to install. As always, confirm spring length and travel clearance for your specific chassis to ensure correct operation.
