Z31 Suspension Spring Differences[edit]

Looking to upgrade the handling or stance of your Z31? If your rear is sagging or you want a firmer ride, this guide covers everything you need to know about Z31 (1984-1989 300ZX) springs—stock, aftermarket, and interchangeable options.

Pro Tip:All Z31 springs are interchangeable across all years and models—2-seater, 2+2, Turbo, and Non-Turbo. No fitment issues!

Swapping Factory Springs[edit]

Spring swaps between years/models:Any Z31 spring fits any Z31. You may see minor changes in ride height or stiffness depending on which model's springs you use.Factory Performance:1987–1989 Turbo models have stiffer springs than Non-Turbo models.Stiffest Stock Option:The 1988 Shiro Special Edition springs are the firmest you can get from the factory.

Aftermarket Spring Options[edit]

Popular brands:Eibach, Tokico, and more are available for the Z31.Progressive Rate (Variable) Springs:Eibach springs, for example, are variable rate. They offer a smooth ride in normal driving and stiffen up during hard cornering for better handling.How to identify:Progressive springs have one end with tighter coils—these compress first for comfort, while the rest engage for performance as you push harder.

Note:All factory Z31 springs are color-coded for easy identification based on their application.

WARNING - Do this modification at your own risk. We Are not responsable for any issues of your own doing.

Spring Lookup Tool[edit]

Use the charts below to identify the model and specs of your Z31 springs. Clean your spring and look for the color code—it will be two dots painted on the spring coils. The color combination identifies the spring model, and you can check the rates listed in the tool below.
