These lower shock plates work great when mini-tubbing the rear of your car for larger rear tires. Because they do not have the same bolt pattern as the stock spring plates on most axle housings, use our lower shock plates with our adjustable leaf spring pads and U-bolts. The shock plates are stronger than stock and use 1/2" U-bolts and a 1/2" bolt for the lower shock mount. They come in an electroplate finish and are available for either staggered inboard, staggered outboard, or shocks on the same side of the rear axle.Electroplated stock lower shock plates are designed to work on a stock rear suspension vehicle that has not been mini-tubbed. These plates are stronger than stock and use the stock U-bolts and the stock shock mount positions.
