Wilson Manifolds shear plates are designed to maximize the performance of engines using tunnel ram-style manifolds. Designed to help improve the signal to the carburetor and flatten the fuel curve, these plates are precision-machined from billet aluminum and are anodized for durability and corrosion resistance.

They also feature a specifically sized anti-reversion groove machined into the bottom of the plates to help turn back reversion pulses. The extended portions of the plates also block reverse flow and help to atomize fuel for reduced puddling in the manifold. These 1/2 in. thick shear plates are available for 4150, 4500, and split Dominator carburetors.
