Details

MSD is excited to announce the next generation of 6-series ignition controls the 6AL-2. The all new ignition control combines a new housing, new digital controls and more power in a sleek package. Inside the new cast aluminum housing you'll find an advanced micro-controller that manages the timing and RPM of the ignition. The spark output of the new box has been turned up to 535 V of primary voltage with spark energy reaching up to 135millijoules. The multiple sparks of the 6AL-2 burn in the cylinder for 20 degrees of crankshaft rotation to ensure complete combustion. Two more great features are the rev limits.

There are two rev limiters; one for high end overrev protection and another you can activate off a clutch or trans brake to set a launch limit. This feature will help your car blast off the starting line. Adjustments are made via four rotary dials for 100 RPM increment control.

Package Dimensions: 10.9 x 9.8 x 2.7 inches

Part Number: MSD-6421

  • Using multiple warehouse located through different states enables us to find a location nearest to you.

FREIGHT SHIPPING

  • Order containing items over 150 pounds or oversized required to be shipped via freight shipping. What this means for you is your items will be shipped via semi-truck to your address and will require a signature upon delivery.

SHIPPING TO INSTALLATION PROCESSIONALS

  • It could be advantageous to ship directly to a professional installer instead of your home address. Just keep in mind, a signature is required for delivery, freight companies cannot promise delivery within business hours, and shipping damages should be reported upon delivery. If you're okay taking on the risks associated, we can happily send it to the address of your choice. If you go this route, please tell us if the delivery address will have a loading dock; otherwise a liftgate will be provided.
