Description
Elevate your 2023+ Nissan Z’s handling with the STILLEN Adjustable Front & Rear Sway Bar Kit (304345), designed to reduce body roll, improve cornering, and dramatically enhance stability. This high-performance sway bar kit is ideal whether it’s the first step in a suspension upgrade or the finishing touch to a fully upgraded coilover and control arm setup.
STILLEN’s sway bars are engineered to maintain the factory outer diameter, allowing the reuse of OEM bushings for a quieter, maintenance-free experience. Using high-strength aircraft-grade steel with thicker walls, these bars are stiffer than stock to keep your Nissan Z planted and responsive through tight corners, spirited drives, or track days.
The kit includes a 5-way adjustable front bar (21–48% stiffer than stock) and a 3-way adjustable rear bar (37–70% stiffer), giving you the freedom to fine-tune your car’s handling characteristics to your driving style. Factory-style bushing collars prevent the bars from walking or shifting under high-load cornering, maintaining precise control and predictable handling.
Finished with a durable red powder coat, these bars resist corrosion while offering a striking visual upgrade under your Nissan Z. Designed and manufactured in-house at STILLEN in Costa Mesa, California, each sway bar is meticulously inspected to ensure quality and performance.
Whether driving on the track, winding roads, or city streets, the STILLEN 304345 Nissan Z Sway Bar Kit delivers improved balance, sharper turn-in, and a more connected driving experience.
