SPL Parts Rear Mid Links for 2007-2025 Nissan Z, 370Z & Infiniti G35/G37/Q40 (SPL RML Z34)

Fits select 2007-2025 Nissan Z (RZ34), 370Z (Z34), and Infiniti G35, G37, and Q40 models.

SPL Rear Mid Links (RML) replace the factory spring bucket arms, converting the rear suspension to a setup that offers total control over rear toe, spring rate, and corner weighting. The integrated threaded spring perch is designed to accept common 60mm ID springs, allowing for precise ride height adjustments. To ensure proper geometry, the upper spring perch features a linear adjustment range to maintain alignment with the spring location and minimize binding.

For maximum alignment stability, it is highly recommended to pair these mid links with the SPL eccentric lockout kit (ELT Z34). This replaces the factory eccentric bolt, which is prone to slipping under high lateral loads, with a fixed bolt to lock in your alignment settings and prevent accelerated tire wear. These links are engineered for high-performance use, utilizing PTFE-lined FK rod ends for maintenance-free operation and reduced bushing deflection.
