Our Front Coilover Conversion for the Z31 300ZX includes shortened OE strut casings and spindles rebuilt with KYB AGX Short Stroke shocks. AGX's are adjustable, allowing you to take the car from sport to race heights. They come with your choice of HyperCo Spring or you can upgrade to Swift Springs!

Your front spindles will be required as cores to complete this coilover build. 

These are built on a custom-order basis with nearly any custom spring rate you want available.

We offer store credit for your old strut casings as well! They must be in unmodified and in good useable condition to recieve full credit.

You can send them to us at 4211 Business Drive Suite A, Shingle Springs, CA 95826. Please include a piece of paper in the box that has your name, phone, number, email, and billing address on it. 

Depending on current demand, fabrication time may be 4-8 weeks
