The new APS™ Alternator features a CNC machined billet aluminum housing that delivers great looks with precision and strength. The power producing components are just as impressive!
After selecting an alternator for your engine, simply pick the right bracket kit for your application. Kits are available for many GM, Ford and Chrysler applications with more being added.
The Slide Loc mounts allow you to position the alternator in the best location for your application. The billet aluminum brackets produce a strong installation.

Advanced Power System™
Alternator
The performance of your race car's ignition relies on the charging system. Since these systems go hand-in-hand, it was only time before MSD designed and offered a high output alternator. Our new line of Advanced Power System™ Alternators will be available just in time for the 2004 racing and cruising season!
Don't let the billet housing fool you as there's much more beneath this great looking housing. MSD engineers have spent thousands of hours testing different internal components, materials and windings. A special rectifier with 50 amp diodes improves control and reliability while a new surface mount regulator isolates and protects from high voltage spikes. Even the bearings were hand picked to withstand heavy axial loads and high rpm.
Not only does the precision machined housing provide cool looks and great strength, but it also delivers a new universal mounting design called Slide-Loc. This technology allows one unit to be mounted to a variety of engines by selecting a bracket kit. (For speedshops, this feature means that you only need to stock one alternator!) The bracket installation kits are available separately for a growing number of different applications.
Two models will be available in three outputs; a 105 amp, 130 amp and 160 amp version in either a direct plug-in installation or a one wire model.
Slide-Loc Mounting
Patent PendingMSD's revolutionary Slide-Loc assembly provides nearly universal mounting! Simply install the slide mounts into place then install the bracket kit for your application. More mounting kits will be available soon!

MSD Alternator VS Engine RPM and Alternator Drive Ratio
APS Pulleys
Each Pulley is cut from a billet of aluminum and is supplied with a great looking MSD cap to cover the mounting nut. The Pulleys are designed to give you an approximate 3:1 ratio with a standard crankshaft pulley.

APS Alternator Pulleys and Brackets

Our APS Alternators are becoming more and more popular and our mechanical engineers are trying to keep up with new bracket kits and pulleys. The new Pro-Billet Pulleys are smaller in diameter for engines that see a lot of low rpm operation, such as street rods. This is especially important on cars that have the AC set on freeze, with the radio cranking and while the electric fuel and water pumps are humming along.
