Direct-Fit Bolt-In Mid Plates

Recommended for moderate- to high-horsepower applications, mid plates easily bolt to g-Machine-subframe-equipped 1967-69 Camaro/Firebirds and 1968-72 Novas, with optional brackets, and stock or g-Machine-equipped 1962-67 Chevy II/Novas.

By directly coupling the rear block face to the chassis, acceleration response and torque capacity are greatly increased without overstressing the sidewalls of the engine block. When used with our optional motor plate, the mid plate also improves chassis rigidity by utilizing the engine block as a stress member. Mid plates are CNC-laser-cut, .134"-thick, zinc-plated steel with no trimming or notching required for installation.

Note: Chevy II mid plates mount to inner holes of factory main subframe joint. Kits include frame-adapter brackets, enabling the mid plate to be removed and reinstalled without disrupting the main subframe joint.

Note: Camaro g-Machine subframe installation requires selection of optional mid plate brackets at time of subframe purchase.
