SPL Parts Dogbone Rear Traction Arms - 03-08 Nissan 350Z / 03-07 Infiniti G35

SPL Parts Dogbone Rear Traction Arms - 03-08 Nissan 350Z / 03-07 Infiniti G35 is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 03-08 Nissan 350Z / 03-07 Infiniti G35. SPL Parts develops American-made suspension solutions for drivers who need more alignment range, less unwanted compliance, and more consistent chassis behavior than factory hardware typically provides.

This adjustable longitudinal suspension link replaces a compliance-heavy factory connection and provides a more direct way to control wheel motion under acceleration and braking. Depending on the chassis geometry, link-length changes can also be used to influence anti-squat characteristics and wheelbase position. Reducing deflection helps the rear suspension react more consistently to throttle inputs, improving mechanical grip, transient response, and confidence when loading the tire on corner exit.

Why it matters: On this application, the goal is to keep the tire and upright closer to the intended alignment as loads rise, giving the driver a more repeatable platform for braking, turn-in, mid-corner balance, and power application. Adjustment is most valuable on lowered or competition cars where the factory geometry has moved away from its intended operating window.

When combined with quality dampers and tires, precise suspension links help make chassis tuning changes easier to feel, measure, and reproduce.
