The Traxxas 6823R Bulkhead Tie Bars are precision CNC-machined from durable 6061-T6 aluminum and feature an anodized finish for long-lasting strength and corrosion resistance. Designed as a direct bolt-on upgrade, these tie bars increase chassis rigidity and reduce flex during hard acceleration, jumps, and rough terrain driving. They are compatible with the Traxxas Slash 4X4, Stampede 4X4, Rustler 4X4, and Rally 4X4 models, making them an ideal upgrade for improving durability and overall handling performance.
