Rear Sub-Frame Align and Lock Bushing Kit

The Whiteline KCA349 Rear Sub-Frame Align & Lock Bushing Kit is engineered to address body flex experienced under moderate acceleration, braking, and cornering loads. By minimizing bushing compliance and modifying rear sub-frame inclination, this kit significantly reduces chassis flex, ensuring that critical alignment angles and spring rates are maintained. This allows every component within the suspension system to perform as intended, leading to improved handling and stability. The kit is particularly beneficial for vehicles equipped with upgraded springs, shocks, or sway bars, and is considered essential for serious performance applications. This kit features a unique design that places rings in distinct planes to achieve its alignment and locking functions. The installation process typically takes approximately 2 hours. The Whiteline KCA349 kit is compatible with a range of Nissan vehicles, including the 300ZX (Z32) from 1990-1996, the 180SX, the 200SX, and various Skyline models. Specific fitment includes the 2-Seater and 4-Seater (2+2) variants of the 300ZX, with both VG30DE (Non-Turbo) and VG30DETT (Twin Turbo) engines covered for applicable model years.
