    Leave it to MSD to build an all-out performance distributor to replace the OEM GM LT1 Optispark!

    MSD's precise housing, new pickup assembly and distributor cap, and trick timing adjustment mechanism all add up to this reliable MSD LT1 Pro-Billet Distributor. Different from OEM, MSD's pickup is an advanced optical encoder, which is stable during extreme RPM. The rotor is bolted to a drive assembly that is indexed to the shaft and steadied by a large ball bearing assembly. The distributor is also equipped with a fresh-air vent and extra thick mounting surface to eliminate leaks. This MSD LT1 distributor includes a heavy-duty cap, rotor, and necessary components required for installation.

    Once installed, you can adjust the ignition timing +/-6° with just the turn of a screw--an industry first!
