Xtreme-Grip™ Vintage Front Suspension System “Builder Kit Radial X”

This system is designed for a custom car builder for many vehicles.

Some of the components are left unwelded so that you can customize the fitment to suit your chassis.

Vehicles: Used on Ford Falcon, Mercury Comet, Ford Fairlane, Vintage Ford Trucks (+others)

Vintage Fords have lightweight flimsy unibody chassis that can compromise handling.  CorteX engineered our suspension system “builder kit” to increase chassis strength and stiffness for superior response.

Complete Redesign with Modern Geometry

Xtreme-Grip Vintage Front Suspension System Builder Kit is suited for today’s performance tires.

The geometry optimizes the roll center height, lateral roll center migration, and minimizes bumpsteer all the while allowing the build to adjust ride height as much as 2.5 inches to achieve the optimal stance both at the track and on the street.

The Xtreme-Grip Suspension “Builder Kit” Transforms Handling

If you’ve ever driven a vintage mustang and shared the road with modern cars you understand that it can be a white-knuckle ride. Even with standard aftermarket improvements that are readily available, the steering is sloppy, vague, and unresponsive to driver inputs. With the investment required to buy and maintain a vintage mustang these days, we feel it makes sense to spend a small percentage of the total vehicle value toward excellent handling.

There are numerous front suspension systems on the market that are based on the OEM Ford geometry and they just do not measure up to CorteX’s standards.  That is why we went through the trouble of re-engineering everything on both the front and rear suspension to offer customers a complete system that is capable of supercar levels of handling and control.


Due to the custom nature of these kits, we encourage you to call to order. We will work with you to determine the proper shocks, brake system, and steering rack system for your setup.
