What is the main benefit of using monoball bushings over stock rubber ones?

Monoball bushings replace the flexible rubber with a low-friction spherical bearing. This eliminates bushing flex and bind, which helps maintain suspension geometry under load. The result is more precise handling and better feedback from the road.

What type of bearings are used in this kit, and how do they last long?

This kit features FK Racing Bearings, which are known for their performance and durability. They include a self-lubricating Teflon liner that helps reduce wear and friction, contributing to a long service life.

What material are the bearing shells made from, and how precise are they?

The bearing shells are CNC machined from 6061-T6 billet aluminum. They are machined to very tight tolerances, specified at 1/1000th of an inch, ensuring an accurate and secure fit within the knuckle.

Product Details

SPL Parts is known for making well-built suspension components that help racers and enthusiasts get the most out of their vehicles. If you're looking to dial in the rear suspension on your 1990-1996 Nissan 300ZX (Z32) without HICAS, these Rear Knuckle Monoball Bushings are a serious upgrade over the stock rubber. The factory bushings can flex and bind, which hurts handling and makes the car feel vague. These replace that mushy rubber with low-friction spherical bearings.

By eliminating that flex and friction, these bushings help maintain your suspension geometry exactly where it should be, even under heavy load. This translates to more precise handling and better feedback from the road, so you know exactly what the car is doing. SPL uses FK Racing Bearings, which have a self-lubricating Teflon liner for long life and consistent performance. The bearing shells are CNC machined from 6061-T6 billet aluminum to incredibly tight tolerances, ensuring a precise fit. This kit is sold as a complete set for one car and is proudly made in the USA.

When you're rebuilding the rear suspension on your Z32, especially if you're aiming for improved track performance or just a more connected feel on the street, these monoball bushings are a key component. They are designed to work with the factory knuckle and suspension setup, but will significantly change the feel of the rear end for the better. Refer to the manufacturer's installation instructions for details on fitting these to your vehicle.
