Tesla Model 3 / Y Mountain Pass Performance Rear Traction Arms

Mountain Pass Performance Rear Cyber Traction Arms For The Tesla Model 3 & Model Y. Gain Sharper Acceleration and Improved Suspension Response.

The Mountain Pass Performance Cyber Rear Traction Arms offer a serious performance upgrade over the soft, stamped factory arms on the Model 3 and Model Y. By replacing the OEM rubber bushings with solid, sealed spherical bearings, these traction arms eliminate unwanted deflection, allowing your suspension to perform with precision and predictability.

Ideal for high-performance street setups or track-focused builds, these arms play a key role in controlling rear wheel movement under load — especially during acceleration and cornering. The enhanced rigidity results in improved feedback, better response, and increased confidence behind the wheel.

Developed as part of MPP’s Cyber suspension series, these arms feature laser-cut stainless steel construction, TIG welding, and a durable black powder-coated finish. They’re designed to be a bolt-on upgrade and come pre-set to OEM length for hassle-free installation and fine-tuning.
