6868 Springs, rear,+20%

Traxxas 6868 rear springs (+20% rate) are a pair of high‑rate coil springs designed to be 20 % stiffer than stock for the rear shocks on Traxxas 4×4 models like Slash 4×4, Stampede 4×4, Rustler 4×4, and Rally; these springs increase support under load for improved handling during high‑speed cornering, jumps, and heavy‑vehicle use, helping maintain ride height and reduce bottoming compared to standard springs.
