For cars that are 57" to 61" wide at the B-post and have a wheel base of 110" to 118". For best fit, assemble the main cage and rear frame rails inside the body. Use with our Eliminator II 4-link and tubular A-arm front suspension. Ground clearance is 3-1/2" at the 4-link crossmember and 3" at the firewall. The front and rear frame rails join at the main hoop crossmember allowing you to make the rear rails narrower, as little as 18" outside 4-link bracket width, for bigger tires. The 4-link support tubes mount off the main hoop to the 4-link in correct relationship to the rear axle centerline, on long wheel base cars. The roll cage assembly consists of 1-5/8x.134" wall and 1-1/4x.120" wall ERW tubing. Double frame rails in the center of the chassis increase rigidity for higher horse power applications. The kit includes a pair of front frame rails; a pair of rear frame rails; 1-5/8" round main hoop crossmember; two 4-link support tubes; 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.
