Avanti Technical Specifications

Technical Specifications–Hog Troughs

Better know as "hog troughs", the torque boxes were designed to mate the Avanti fibreglass body to its Lark frame. They are called "hog troughs" because that's what they resemble when separated from the frame. These formed steel channels are riveted and bonded to the outer underside of the Avanti body extending from the rear of the front wheelwell to the front of the rear wheelwell. They bond the wider Avanti body to the narrower Lark frame to prevent damage to the fiberglass body.

They are not "hollow." The top is open, the steel forming a three-sided box. Studebaker engineers wanted to increase strength and rigidity with the "hog troughs" to resist the forces of torque without increasing the weight of the 3,400 lb. Avanti any more than necessary.
