SPL Parts 90-96 Nissan 300ZX (Z32 w/HICAS) Rear Knuckle Monoball Bushings

If you're working on the rear suspension of your 1990-1996 Nissan 300ZX Twinturbo with HICAS, these rear knuckle monoball bushings from SPL Parts are a serious upgrade over the factory rubber. The stock bushings can get soft and flexy over time, which hurts suspension geometry and makes the car feel vague. These replace that rubber with high-precision spherical bearings, keeping your suspension aligned and responsive, even under hard cornering.

SPL uses FK Racing Bearings that feature a self-cleaning Teflon liner, designed for long life and smooth operation. The bearing shells are CNC machined from 6061-T6 billet aluminum to incredibly tight tolerances, ensuring a perfect fit in your knuckle. This setup eliminates the flex and friction found in rubber bushings, which translates to much sharper handling and better feedback from the road. They're made in the USA and sold as a complete kit for one car.

This kit is specifically for the Twinturbo models and does not replace the HICAS balljoint itself. If you're rebuilding the rear end of your Z32 and want to maximize suspension performance, these monoball bushings are a solid choice.
