This kit is typically used when fabricating a drag car rear suspension. A complete frame rework will be needed in order to use these brackets.

Fitment Do you sell a 4 link with a radios or is there enough material to cut this to fit an arched frame on my 1980 corvette

Sorry we do not offer frame brackets with a radius cut in the back side for welding to an arched frame rail. These could be cut slightly to help fit to an arched frame rail but it will certainly require some material to be added if you want it to fit the arch the entire way up.

I am looking to use this kit with adjustable ridetech air shocks. Will this four bar setup work with dropping the air bags 4-6" when parked? The air bags will only be lowered all the way when parked and running at normal height when driving. If the four bar is set up parallel when at operating height will it have enough downward swing to allow the suspension to drop 4-6"?

6" of downward travel shouldn't be a problem with this kit.

Speedway part number 91649069. This heavy duty rear 4 bar kit is a universal kit, that will fit a variety of different applications. It should work fine on a 52 Chevy with a Camaro 10 bolt. The rear brackets will fit 3" diameter axle tubes out of the box, which is what the Camaro rear should have.

with this kit do you have to weld the brackets on the diff or do you need to use a birdcage to mouinbt on the diff also does this kit come with directions as to where to weld the mount on your car

This kit has to be welded, you need to locate your rear end In the car first and then that will allow you to out the brackets in the car correctly.

This is a heavy duty four bar kit for HIGH horsepower applications. It does not have a specific application and is universal for many rod and drag vehicles. It is designed for a 3” axle housing tube but could be modified for other O.D. tubes if needed. It will require the use of a panhard bar for side to side stability. From Willys gassers to blown Tri-5’s to Hot rod pickups, this will handle the horsepower.

has anyone got install info on this product as in which way the brakets mount to the diff housing etc?????

If you look at the brackets the ones that mount to the rear end housing are notched to fit against the rear end the your other brackets you will mount to the frame of the car with the flat side to the frame. Any other questions feel free to call and speak with our Street Rod Tech department.
