CJ-7 Moly Chassis

 We Can Build you just about any kind of chassis you could want. Our specialty is building a chassis to fit your application, the chassis we build is for your car, they are not a mass produced chassis which is generic in design we build it to fit the suspension you want and your body. When we build a chassis we need the body, rear end and tires that is going to be used along with the ride height. Because each chassis is built to the customers wants, with in reason.

  We have built every thing from a front clip for a 1957 Chevy using Mustang spindles to a Complete 1934 Willys AA/GS race car with a custom torsion bar double A-Arm front suspension.

  The cost for a Custom Chassis depends on how much of the suspension we have to build from scratch, the major cost in a custom chassis is suspension. We can build from a complete custom suspension to adapting most any suspension out there to your chassis. Please remember there are limitations to what will fit and work properly. We can design a front suspension if you want something different or there is nothing that will fit inside the body of your car.

 We have used the Mustang II front suspension design, we have even modified Mustang II suspension designs where we had to alter the width to fit in early Ford Model A's and a 1929 Essex Coupe which we built a chassis for, ever try to find a chassis from Fat Man for a 1929 Essex 3 window coupe. We have used Camaro and Nova front clips and even late model Corvette front and rear suspensions. Where a custom suspension is wanted or required we use two different computer programs to design special front suspensions. To allow for a desired caster and camber change, a desired roll center and anti squat or anti dive. We take care of "Bump Steer" (wheels change direction as suspension moves up and down) a problem many adapted suspensions have. By using our computer programs to analyze the suspension and make the necessary changes we make sure every thing works right.

 The basic cost for a rolling chassis with OEM suspension components and brakes start at $12,000 and this would be a chassis ready to accept your body and drive train. This does not include any Electrical, Fuel Lines, fuel tank and tires and wheels .

 If you would like to view some of the Custom Chassis we have built over the last 17 years just click on the Chassis Photos below. But please remember each chassis is built to that customers car. We do not build a generic chassis or a kit we do not belive in "one size fits all"!!!!!!!!!
