Twisting in the engine block causes bore distortion resulting in catastrophic cylinder wall friction. Do not let this happen to you! You can lose your connecting rods, pistons, crankshaft or even your whole engine block.
The Valley Girdle Pro stabilizes and strengthens your engine block to prevent block twisting and cylinder bore distortion. It will add significant strength and rigidity to your engine! You will also find a gain in horsepower! Valley Girdle Pro's are made in the U.S.A.
