One of the most important features of the MSD Pro-Billet Distributors is the adjustable mechanical advance assembly. The mechanical advance, sometimes referred to as centrifugal advance, allows you to accurately and easily modify the advance curve to match your specific application. MSD engineers have spent many hours at the dyno controls and in our labs perfecting this great distributor feature. A variety of timing curves can be achieved simply by changing the advance springs and stop bushing. The stop bushing determines the amount of mechanical advance that can be achieved. Each distributor comes with two heavy silver springs installed which give the curve the slowest advance rate. These MSD distributors introduced the first aftermarket distributor crafted from a billet of 6061-T6 aluminum. These Pro-Billet custom truck parts Distributors are now available for most popular domestic V8s and several other popular engines.
