For cars that are 50" to 54" wide at the B-post and have a wheel base of 96" to 103". For best fit, assemble the main cage and rear frame rails inside the body. Use with our Battle Cruiser 4-link and tubular A-arm front suspension. Ground clearance is 4" at the 4-link crossmember and 3" at the firewall. Frame rails are made of 2x3x.120" mandrel bent tubing. These mandrel bent frame rails do not have the ugly wrinkles under the bends like other manufactures. The front and rear frame rails join at the main hoop crossmember allowing you to make the rear rails narrower, as little as 20" outside width, for bigger tires. The roll cage assembly consists of 1-5/8x.134" wall and 1-1/4x.120" wall ERW tubing. The kit includes a pair of front frame rails; a pair of rear frame rails; 2x3"main hoop crossmember; upper and lower A-arm mounts; tubular Pinto rack-and-pinion crossmember and mounts; complete roll cage assembly; rear coil-over upper shock mount with tabs and hardware; one engine mount loop; CAD drawing; and instructions. Due to sanctioning body rule changes, the purchaser takes all responsibility for assembling the chassis to meet the specific class you are running. We do not guarantee these parts to meet any specific class requirements. Funny car cage is optionally available.
