Our 300zx Z31 Solid Differential mount has absolutely zero no slop. The mount is a steel weldment which has no flex, keeping your differential mounted as solid as possible. However, with this mount being solid, you will get vibration and noise through the chassis. If you are looking for a less race only version, check out our bushing version also for sale!

This is an okay product. Installing it was a big pain. What I thought would take me half hour took me close to hour and a half. The design of the new bracket makes it hard to tighten the top bolts to the chassis. I also thought it would make the clunking less loud, but it made more noticeable and loud. Sounds like my differentials going to explode when I shift gears. Definitely going to have to go with the differential mount with bushings.
The Apex Engineered Z31 (300ZX) Solid Differential Mount is compatible with all Nissan 300ZX models produced between 1983 and 1989. This mount is specifically engineered for the Z31 chassis to provide a rigid connection for the drivetrain during high-performance driving.
Installing the Apex Engineered Z31 (300ZX) Solid Differential Mount is more difficult than a standard bushing because the steel weldment has absolutely zero flex. For a successful installation on your Z31 300ZX, precise alignment is required to secure the differential as solidly as possible to the chassis.
The Apex Engineered Z31 (300ZX) Solid Differential Mount eliminates the slop found in factory rubber bushings by using a rigid steel weldment. This upgrade ensures your Z31 300ZX differential remains stationary under load, though it will increase vibration and noise compared to the OEM setup.
Each Apex Engineered Z31 (300ZX) Solid Differential Mount kit includes a lightweight steel weldment finished in a tough powder coat. You can customize your Z31 300ZX build with various color options including Hammered Black, Red, Gray, or several gloss finishes to match your suspension.
If you find the Apex Engineered Z31 (300ZX) Solid Differential Mount too aggressive for street use, Apex Engineered also offers a Bushing Differential Mount for the Z31 300ZX. Both mounts can be paired with our Z31 Front and Rear Suspension Kits to complete your Track Attack setup.
